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.

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 …

Minerals will form from magma and lava as the lava cools; the rate of cooling will determine the crystal size in the mineral formed. t or f?

The given statement is True. Minerals will form from lava as the lava cools down. The rate by the lava will cool down determines the crystal size in the minerals. If the sticky magma cools quickly, then it forms small crystals. If the magma is trapped for a longer time …

“Ocean currents result from two processes: the wind on the surface of the water and variation in water temperature and density. These ocean currents are convection currents. Under the tropical sun, water at the equator warms up. At the frigid poles, seawater cools down and sinks. Convection cells are set up with warm water moving along the surface to the poles and deep cold water flowing toward the equator. Changes in the density of ocean waters, caused by changes in salinity re also important in the formation of ocean currents. Ice formation near the poles leaves salt behind in the remaining water. This denser, more saline water sinks, creating its own density-driven currents. Surface winds also set surface currents into motion.” Can you pick the statements that accurately describe oceans currents? Check all the statements that are true. ‘Both the wind and solar energy influence ocean currents.’ ‘Warm water flows away from the equator toward the poles.’ ‘As the salinity of ocean water increases, density decreases.’ ‘Cold water sinks, warm water rises, creating a convection current.’

Answer: The rainfall increases the mineral content of ocean water. Explanation: The minerals in the oceanic water are added by the rainfall through surface runoff. It is a phenomena in which the large volume free flowing water flows over the surface of the soil. This water is not absorbed by …
