If an object that enters the Earth’s atmosphere does not completely disintegrate, its remains can impact the Earth. True or False?

[ad_1]

Answer: True

Explanation:

The meteorites or other objects entering from the earth atmosphere from the solar system. Some of these small sized objects are subjected to ablation in the earth atmosphere. They get destroyed in the atmosphere. But objects which are larger in size they remain unaffected and hit the surface of earth with explosion. These objects appear as shooting stars.

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

[ad_1]

Answer:

The correct sequence according to the question is steps- 4→1→3→5→6→2→7.

Explanation:

The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as the rock cycle.

The steps of the rock cycle in sequence according to the question are:

1.  Breakdown of rock by weathering into regolith- step 4

2.  Dumping and deposition of regolith in a reservoir- step  1

3.  Erosion and transportation of regolith by rain or wind- step  3

4. Cementing of the deposited layer to form sedimentary rock- step  5

5. Conversion of sedimentary rock to a metamorphic rock due to intense heat and pressure- step 6

6. Conversion of  metamorphic rocks to magma due to the melting of metamorphic rocks-
step 2

7. Conversion of magma to igneous rocks due to volcanic activities and cooling of magma-  step 7

Therefore sequence according to the question is steps- 4→1→3→5→6→2→7 is correct.

What role does thermal convection play in earths structure?

[ad_1]

Answered by answersmine AT 22/10/2019 – 04:28 AM

Heat transfer by natural convection plays a role in the structure of Earth’s atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be seen as clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics.

Natural Forces Affecting the Driver:

1. While the car stops, the person continues moving the way that the car were moving and then hits the obstacle in the car or the person can be thrown out of the vehicle. If the person wears belt, he will stop moving with the vehicle and won’t hit the obstacle.

2. We count approximate kinetic energy using the formula K = v^2. So the vehicle which is moving at 30 mph will have four times less kinetic energy than vehicle which is moving at 60 mph. If they have the same road conditions, the breaking distance will be four times as great for the car moving twice as fast.

3. Kinetic energy depends on object’s mass and velocity and it has direct relationship with the stopping distance. The lesser mass of the vehicle = the lesser kinetic energy and lesser stopping distance. => If both vehicles have the same velocity, then small vehicle has lesser kinetic energy than large vehicle.

4. We know that kinetic energy has this relationship with velocity K = v^2. So the best way to prepare to enter sharp curves in the roadway is to lower the speed. The most appropriate speed is 20-30 mph, but it depends on road conditions and car’s breaks condition.

5. Car crashes can happen with everyone so the best way is to be prepared. First the driver should wear a seatbelt while he’s driving. He should check his tires and breaks condition regularly. And also it’s important to slow down the vehicle while entering sharp curves. Without following these rules, the driver can get catastrophic injuries in a car crash.

Signs, Signals, and Pavement Markings: 

1. It doesn’t matter where you go. All you need is to learn highway code. It’s very different to know the meanings of every road sign. Also, it’s necessary to check your car’s conditions and you should take some spare parts for your car in case of accidents. So wherever you go, it’s important to be prepared.

2. You should stop before crossing and take few minutes to make sure there is no train approaching. If there is no train approaching, you can pass a railroad crossing. If you see approaching train, you should wait until it will pass a railroad crossing.

3. You should stop before the lights and wait to check the traffic movement and signs. Make sure that everything is safe and pass the intersection. Don’t move fast to avoid accidents.

4. Flashing yellow light means that it’s not necessary to stop but you should to pay attention on the traffic movement. So it would be better to yield before the lights and make sure if it’s safe to move. After that you can cross the intersection.

5. The line change means that the lane changes and you can’t cross solid lines. Pay more attention on road marking because it shows how you should behave on the road or highway.

6. As you approach the next exit and  your passengers need to use the restroom and get some food, you should look for green signs which indicate food and rest stops. You should to slow down if you don’t want to skip the sign.

7. When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway which indicates that there is oncoming traffic and this is a two-way highway.

The stratospheric chemical that prevents much of the solar ultraviolet radiation from penetrating to earth’s surface is:

[ad_1]

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

Answer: The population of the burrowing owl may increase in its new surroundings.

Ecological niche is the role or function an organism performs in the ecosystem in order to survive. It describes how an organism obtain it’s food, type of habitat chosen for survival, season used and duration of mating, how it interacts with the other organisms and others.

In the given situation, the population of the burrowing owl may increase in its new surroundings is the least likely outcome of the habitat changes that are described. This is because of the fact that as with the construction of more cities the burrowing owl habitat will be destroyed. These owls will loose their habitat and their ecological niche will be drastically affected. All these consequences will result in the decline in the population of burrowing owl instead of increase in the new surroundings.

The answer is plate tectonics theory.

The idea that earth’s lithosphere is divided into large, moving sections is called the Plate Tectonics Theory.

The Plate Tectonics Theory is not attributed to any single person or geologist. In fact, it developed over a number of years due to scientific exploration and the research of the Earth’s crust.

The theory explains how the Earth is divided into large sections of plates, that are always moving, leadint to changing shape of the landmass on Earth. The movement of these plates is what casues earthquakes.

It is based on the theory of continental drift and was widely accepted in the scientific community by the 1950s.

What do scientists use to learn about earth’s core A earthquake waves B mines C temperature measurements D wells

[ad_1]

1)

Definitely, the heat that drives the convection cells located in Earth originates in the inner core. I consider this option to be correct as inner core is the Earth’s innermost part and its temperature could be approximately 5400 °C, so I bet this is the most suitable option.

2)
According to the fact that magma plume ejected magma through a moving crust, this is a great example of a mid-ocean ridge, because this phenomenon consist of an underwater mountain system that were formed due to the plate tectonics. 
3)
 When an earthquake occurs, the actual point of earth movement is called crust and the point on the surface right above this is called the mantle. From the definitions of these two points you can see that their meaning cleanly coincides with the task.
4)
As far as I remember, in order to prevent a mass erosion event, such as the 1930s Dust Bowl, farmers should keep the land irrigated. They say that it is very important to overflaw dry area in order to keep it in satisfying condition.
5)
Some scientists take s
eafloor spreading  as a basis and claim that in neares future, slabs lithosphere will split apart from each other again due to tectonic activities. Also, they assume that there is a big possibility that soon  tectonic plates will crash into each other and won’t spread. 
6) 
 The soil is the most essential point of the groving basis, its purpose is to make plants and trees grow, therefore we can make a conclusion that we can’t imagine our life without it.
7) You can include such information as description of the motion of mantle material near the outer edge of it and show the model that clearly shows all the point you describe. Then you should tell about how things that you have seen can impact Earth.

I do hope it will be helpful!
