What is C. They are built up when plates push together.
100
A wall across a river that controls the flow of river water.

What is B. plain
200
A wall along a river or other body of water that serves to prevent flooding by keeping water behind it.

What is B. canyon
300
Cracks in the Earth's surface along which movement takes place
What is a fault?
300
A way to stop beach erosion is to build a tall wall along the rear edge of a beach. When waves come, they hit the ball and lose much of their energy. They cannot carry away as much sand.
What is a sea wall?

It is made up of many cells and absorbs food from its surroundings. C. It is made up of one cell and makes its own food. D. It is made up of many cells and makes its own food.
What is A. It is made up of many cells and feeds on other living or once living things.
400
The remains of living things building up a coral reef.
What is Constructive?
400
How does a hotspot form a chain of volcanoes? A. Volcanoes form above a hot spot. The volcanic mountains move as the plate moves. B. The hot spot allows magma to ooze from a vent. C. The hot spot allows magma to explode from a vent. D. The hot spot forms alternating layers of lava and ash.
What is A. Volcanoes form above a hot spot. The volcanic mountains move as the plate moves.
400
A violent shaking of earth's crust as built-up energy is released.
What is an earthquake?
