Earth Changes Over Time

What is happening when soil, rocks, sand, or mud (weathered materials) are moved over time.

• Weathering

• Erosion

• Landslide

• Volcanic Eruption

The sudden shifts between parts of Earth's crust that

cause the ground to vibrate in all directions . These vibrations can cause cracks in the Earth’s surface

• Landslide

• Volcanic Eruption

• Earthquake

• Erosion

An opening in Earth’s crust through which hot, melted rock is forced up by pressure inside the Earth.

• Landslide

• Volcanic Eruption

• Earthquake

• Erosion

The downhill movements of rocks and earth. The loose

surface of the land slides down a slope.

• Landslide

• Volcanic Eruption

• Earthquake

• Erosion

This carries land away by rainfall and rivers, then redeposits it in the form of pebbles, sand, silt, and mud.

• Weathering

• Wind Erosion

• Water Erosion

• Landslides

Wind causes erosion by moving soil or sand from one place to another.

• Decayed plants and animals, pressure, & erosion

• Decayed plants and animals, oil, & millions of years

• Heat, pressure, & millions of years
