They all provide evidence for plate tectonics

Which one of the following statements is TRUE?

old crust is destroyed and new crust is formed over time

A seashell on top of a hill MOST LIKELY means that

the hill was once under the sea

Which of these statements about the Earth's crust is true?
It's a system of plates that slowly move together or apart
It's a changing, moving surface with the same thickness
It's a layer of solid rock that stays the same all the time
It includes the continents, but not the ocean floor
2
This picture shows what type of plate boundary?
divergent boundary
none of the above
transform boundary
convergent boundary
3
Plate tectonics refers to the theory that
Earth's surface is made of large plates that do not move
the continents float on the oceans like plates
each of the continents on Earth is also called a plate
Earth's surface is made of plates that move over time
4
What landform can be created when two continental plates collide?
mountain range
ocean basin
volcano
canyon
5
The lithosphere is:
broken up into plates
solid outer layers of Earth (crust + upper part of mantle)
the top layer of the atmosphere
6
Which of the following statements provides evidence for plate tectonics?
Same unusual rock layers are found on different continents
They all provide evidence for plate tectonics
The same unusual fossils are found on different continents
Earth's continents move at a rate of centimeters per year
7
Which one of the following statements is TRUE?
old crust falls into the oceans and is destroyed over time
Earth's crust moves, but is never destroyed
new crust is always forming on top of large mountains
old crust is destroyed and new crust is formed over time
8
A seashell on top of a hill MOST LIKELY means that
the hill was once under the sea
all hills were once under water
sea animals once lived on the land
seashells were not parts of living things
9
As the distance increases from a mid-ocean ridge, the rocks
do not change in age
become liquid
grow older
grow younger
10
Lithospheric plates move at a rate of
kilometers per year
meters per year
lithospheric plates do not move
centimeters per year
11
The lithospheric plates of Earth move due to being dragged along with
convection currents in the mantle
the rotation of Earth on its axis
the high tides of the ocean
prevailing winds in the jet stream
