Smaller pieces of rock

The planting of crops on level sections

Occurs when water collects or flows over land that is usually dry.

A violent shaking of the Earth's crust.

The thickest layer of the Earth.

The point on the surface right above the focus.

The mantle and crust form to create...

Two plates that move toward each other. One may move under the other.

Sliding boundaries, plates that slide past each other.

Thin, narrow walls built from the shoreline into the ocean.

The dropping or releasing of sediment that has been moved from one place to another.

A wall across a river.

The remains or traces of a plant or animal that lived long ago.

Cracks in the Earth's crust where movement has taken place.

Deepening or widening of a river or harbor.

Plowing in curved rows that follow the shape of the land.

What does a topographical map show?

A destructive force that breaks down rocks into smaller pieces.

Pipes that carry away storm water.

Boiling fountains of water!

Two plates move away from each other. Melted rock rises to fill the space.

This is made up of minerals, and small rocks, waters, gases, and organic matter.

As the crust shakes, it sends out shock waves of energy.

Where is most of the Earth's fresh water?

The thin, rocky outer layer of the Earth.

A wall along a river or other body of water.

Caused by mechanical erosion, it is formed primarily by the waves from the sea.

When water is collected in an artificial lake. The amount of water stored can be controlled.

The point right under the fault.

This happens suddenly and is formed when weathered rock sinks into a hole.

Caused by erosion, and is a large movement of land that tumbles down a hill.

To help stop erosion, a tall wall can be built along the rear edge of a beach.

Land formed over many years by the build up of sand and dirt just offshore.

Opening in Earth's surface through which melting rock, hot gases, rock pieces, and ash erupt.

The surface layer of soil or the layer we walk on.

The Earth's innermost structure.

What is formed when water and sediment carve away rocky land that juts out into the water?

Melted rock below Earth's surface.

Destructive force in which pieces of rock are moved by water, wind, or moving ice.
