Divergent boundary
Transform boundary


Convergent boundary

Continental riftA.East African RiftB.Himalaya Mountains along the Indian PlateC.San Andreas fault in CAD.Mid-Atlantic Ridge

Question 3

1. Wegener’s Continental drift hypothesis paved the way towards our understanding of how the Earth’s surface is moving and changing!  Which of the follow is NOT evidence that Wegener and his supporters gathered to substantiate (“prove”) the continental drift hypothesis?

Fossils match across the seas
Mountain ranges and rock types match on different continents
Ancient climates match, as seen in glacial desposts across several continents
The continents appear to fit together like a jigsaw puzzle
The mechanism for the movement of the continents was proven, explaining exactly how the plates drifted

Question 7

1. Think About It:  If other planets in our Solar System are not displaying signs of Plate Tectonic motions, what can be inferred about the state of the interior of these planets? (What does this tell us about the state of the interior of other planets in our Solar System)

Question 8

1. When a rock is heated, when pressure increases, or when hot water alters its chemistry, both its minerals and its textures change in a process called _____________.

chemical lithification

Question 9

1. When a sedimentary rock is created it forever remains a sedimentary rock, never changing.

1.          Which of the following statements apply to the asthenosphere, but not the lithosphere?

A.             Zone in the upper mantle that deforms by plastic flowage
B.            Cool, ridge layer of crust and upper mantle that forms the tectonic plates
C.           Deforms mainly by brittle fracturing and faulting
D.                Hard surface which floats on top of molten material

Question 11

Question 14

1. Use the Plate Tectonic Boundary Map on pages 202-203 in your textbook to answer the following questions:

Describe the tectonic motion taking place between then African Plate and the Eurasian plate.  What major geological feature exists there and why?

Divergent Boundary.  Alps Mountain range, formed from plates pusing together and compressing, building up the mountain range.
Convergent Boundary.  Alps Mountain range, formed from plates pusing together and compressing, building up the mountain range.
Divergent Boundary.  Alps Mountain range, formed from plates pulling apart and decompressing, building up the mountain range.
Transform Boundary.  Alps Mountain range, formed from plates sliding past one another therfore building up the mountain range.

Question 15

1. There are two main types of igneous rocks.  Blank 1 igneous rocks are formed from magma that cooled very quickly and are fine-grained.  These can also be called Blank 2 igneous rocks.  The second type of igneous rock is Blank 3 igneous rocks which are coarse-grained because the magma from which they formed cooled slowly.  These can also be called Blank 4 igneous rocks.

A.Biosphere; Atmosphere
B.Hydrosphere; Biosphere
C.Atmosphere; Hydrosphere
D.Biosphere; Hydrosphere

Question 20

1. Sedimentary Rocks are broadly divided into four categories.  For the definitions given, match the correct type of sedimentary rock.

Sedimentary rock derived from plant and animal remains.  And example is Coal, which is formed from partially decayed plants called peat.
Halite is a good example of this type of sedimentary rock.  Halite is an evaporate because the salt precipitates from the seawater
Derived from the weathering of pre-existing rocks.  Sandstone is an example of this type of sedimentary rock

swirling movements of the molten iron particles in the outer core
gravitational attractive forces of the Sun and Moon
electrical and magnetic fields localized in the inner core
