The process by which earth’s surface is broken down into smaller pieces.

After pieces of the Earth are broken down through weathering, those pieces are moved through erosion. It’s the process of moving things from one place to another.

After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.

A slowly moving mass of ice formed by the buildup of snow. They are usually found on mountains or near the poles of the Earth where it is cold. Movement of glaciers can cause weathering and erosion.

A five-thousand-foot-deep canyon located in Arizona. It was carved by the Colorado River over millions of years and is one of the best examples of weathering and erosion.

Naturally occurring rocks that look like a mushroom. They can be formed when sand gets carried by wind and hits the rock. This weathers the bottom of the rock more than the top.

A large amount of mud mixed with water that slides down a mountain due to gravity. It usually causes damage and destruction.

The outermost, rocky layer of the Earth.

Thickest part of Earth's crust located under the land / continents.

Thin part of Earth's crust located under the oceans.

The layer underneath the crust. It is the thickest layer. Plate movement happens in this layer.

The layer between the mantle and inner core. This is the only layer that is liquid - made up mostly of molten iron and nickel.

The innermost layer of the Earth made of solid iron and nickel.

The idea that the world's land masses are slowly moving over time.

The super-continent made of all continents that existed millions of years ago.

Researcher who is known for his theory of Continental Drift.

Evidence of Continental Drift (Wegener)

1. Geometric 2. Mountain/ Rock 3. Fossil 4. Climate

Using sound waves to map the ocean floor, and the size of objects on the ocean floor.

A geologist and officer in the Navy, important in discovering the theory of plate tectonics.

The theory stating that new areas of Oceanic crust are created by the upwelling of magma at midocean ridges causing constant movement on either side.

Evidence of Seafloor Spreading

1. Age of ocean rocks 2. Pattern of positive and negative magnetic charges.

The geological theory that pieces of Earth's crust are in constant, slow motion. This theory explains the formation of mountains, earthquakes, and volcanoes.

Earth's Surface

Weathering, Erosion, Layers in Earth

Term	Definition
Weathering	The process by which earth’s surface is broken down into smaller pieces.
Erosion	After pieces of the Earth are broken down through weathering, those pieces are moved through erosion. It’s the process of moving things from one place to another.
Deposition	After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.
Glacier	A slowly moving mass of ice formed by the buildup of snow. They are usually found on mountains or near the poles of the Earth where it is cold. Movement of glaciers can cause weathering and erosion.
Grand Canyon	A five-thousand-foot-deep canyon located in Arizona. It was carved by the Colorado River over millions of years and is one of the best examples of weathering and erosion.
Mushroom Rocks	Naturally occurring rocks that look like a mushroom. They can be formed when sand gets carried by wind and hits the rock. This weathers the bottom of the rock more than the top.
Mudslides	A large amount of mud mixed with water that slides down a mountain due to gravity. It usually causes damage and destruction.
Crust	The outermost, rocky layer of the Earth.
Continental Crust	Thickest part of Earth's crust located under the land / continents.
Oceanic Crust	Thin part of Earth's crust located under the oceans.
Mantle	The layer underneath the crust. It is the thickest layer. Plate movement happens in this layer.
Outer Core	The layer between the mantle and inner core. This is the only layer that is liquid - made up mostly of molten iron and nickel.
Inner Core	The innermost layer of the Earth made of solid iron and nickel.
Continental Drift	The idea that the world's land masses are slowly moving over time.
Pangea	The super-continent made of all continents that existed millions of years ago.
Alfred Wegener	Researcher who is known for his theory of Continental Drift.
Evidence of Continental Drift (Wegener)	1. Geometric 2. Mountain/ Rock 3. Fossil 4. Climate
Sonar	Using sound waves to map the ocean floor, and the size of objects on the ocean floor.
Harry Hammond Hess	A geologist and officer in the Navy, important in discovering the theory of plate tectonics.
Seafloor Spreading	The theory stating that new areas of Oceanic crust are created by the upwelling of magma at midocean ridges causing constant movement on either side.
Evidence of Seafloor Spreading	1. Age of ocean rocks 2. Pattern of positive and negative magnetic charges.
Plate Tectonics	The geological theory that pieces of Earth's crust are in constant, slow motion. This theory explains the formation of mountains, earthquakes, and volcanoes.
