1. Changes in the Earth’s Surface

2. Erosion Sediments Ridge Trench Weathering
The process in which rocks are broken down into pieces.
Erosion
The process in sediments are carried away by moving water, wind, or ice.
Sediments
Very small pieces of rock like sand.
Continental drift
The movement of continents due to shifting plates.
Ridge
a long, narrow elevation of land; a chain of hills or mountains.
Trench
a long, steep-sided, narrow depression in the ocean floor

3. Fault Crust Mantle Lithosphere Plate Tectonic
a break in the continuity of a body of rock or of a vein, with dislocation along the plane of the fracture
Fault
Plate Tectonic
lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past adjacent plates.
Crust
The uppermost layer of the Earth
Mantle
The thick layer of Earth that is between the crust and the outer core
Lithosphere
Where the solid upper mantel and crust combine.

4. Magma Lava Glacier Volcano Earthquake
Molten material beneath or with in the earth’s crust where igneous rocks are made.
Magma
Lava
The molten or fluid rock that comes from a volcano
Glacier
A large chunk of ice that is moving very slowly creating mountains or valleys in its path.
A vent within the Earth’s crust that spews lava, steam, or ash
Volcano
Earthquake
A vibration from the Earth caused by shifting plates

5. Tsunami Deposition Chemical Weathering
A large sea wave created by an earthquake or volcanic eruption.
Deposition
Sediment that is being left behind during erosion
Mechanical Weathering
The breaking down on larger rock into smaller rock, called sediment.
Chemical Weathering
Changing rock into other materials or dissolving rock.
