2
The process by which tectonic plates move apart at mid-ocean ridges is called ____.
isostatic rebound
sea-floor spreading
reverse faulting
subduction
3
Which of the following is part of a transform plate boundary?
the Marianas Trench
the Mid-Atlantic Ridge
the San Andreas Fault

4
What is chemical weathering?
movement of rock, soil and sand to a different location.
the breaking down of rock by wind and rain
changes to rocks that are caused by chemical reactions
5
What is physical weathering?
The movement of small rock pieces to different locations.
When rock is broken into smaller pieces
The erosion of rock caused by chemical reactions
something rubs/hits rock to break it into smaller pieces
6
How does a glacier change the surface of the land?
It breaks off into smaller glaciers as it melts.
It drags dirt and rock, changing the way the land looks.
Land does not change from its original state
It creates floods as it moves along.
7

tidal wave
mountains
volcanoes
earthquake
8

Transform
Strike-Slip
Convergent
Divergent
9

a sinkhole
a syncline
an anticline
a fault
10
Which is not a cause of physical weathering?
pollution
roots from a tree
wind and water
people or animals
11
True or False: Most earthquakes and volcanoes occur in the centers of continents.
True
False
12
Why do convergent boundaries create large mountains on Earth's surface?
the plates move away from each other
the plates move past each other
they create volcanoes not mountains
both plates are forced up

What is Pangaea?
name of the scientist who first discovered plate tectonics
a type of thick, sticky lava
the process by which tectonic plates move around the Earth
name of the ancient supercontinent
14

inactive
convergent
transform
divergent
15
Convergent plate boundaries ________.
collide
do not move
pull apart
slide past each other
16

chemical weathering
physical weathering
aquifer
mechanical weathering
18

False
True
