The pieces that make up Earth's surface are called…?
Jigsaw puzzle
Pattern
Plate boundary
Tectonic Plates
Earthquakes are caused by plate motion. The plates are constantly moving, and this sometimes causes sudden shaking at the surface.
True
False
What best describes Earth's mantle?
Liquid, melted rock below the outer layer.
The hard, solid rock beneath the plates.
Liquid, melted rock on which the plates move.
The soft, solid rock on which the plates move.
Which sentence about earth's outer layer is true?
When the plates of the outer layer move, there are places were the mantle is exposed to the air and water at the surface.
Although the plates of the outer layer move, the mantle is always above the outer layer and is closer to the air and water at the surface.
The outer layer is always made up of hard solid rock. The mantle is always below the outer layer, and is not exposed to the surface.
The outer layer is sometimes made of hard solid rock, and sometimes made of soft solid rock. It depends on how much magma is rising up from the mantle.

Which of the following best explains the process of seafloor spreading?
The ocean floor is expanding due to volcanic activity at mid-ocean ridges.
The ocean floor is shrinking as tectonic plates converge.
The ocean floor remains static and unchanged.
The ocean floor is being recycled at transform boundaries.
