Layers of the Earth
Name the four main layers of the Earth.
Crust, Mantle, Outer Core, Inner Core
The Grand Canyon is the result of which process?
Constant water erosion by the Colorado River.
Natural features on the Earth's surface are called
landforms
The Earth is comprised of what?
Continents and Oceans
When new land is formed, shaped, or change the results are
landforms
Which layer is composed of mostly liquid iron and nickel?
The Outer Core
What are the four main causes of erosion?
The four main causes of erosion are water, ice, wind, or gravity.
The three main types of this landform are shield, composite, cinder. What is its name?
Volcano
What is a large body of salt water called?
Ocean
Name three natural disasters.
Earthquakes, volcanic eruptions, blizzards, floods, tsunami, tornadoes, hurricanes, famine, windstorms, tidal waves, droughts, hailstorms, avalanches, etc.
Which layer is a rocky layer made up of both solid and liquid?
The Mantle
What is deposition?
the dropping of sediment by wind, water, ice, or gravity.
What landform is created by by volcanic activity, or when rock layers are pushed together.
What is a continent?
A large solid area of land.
Name two things that are caused by tectonic plate movement.
Earthquakes, volcanic eruptions, tsunamis
This layer is made up of rocks and soil, and forms the land.
The Crust
Explain how water could cause weathering.
In the video we watched on landforms, they talked about 15 different landforms. Name 5 of these landforms.
mountains, hills, island, estuary, river, lake, valley, peninsula, isthmus, bay, coral reef, lagoon, pond, plain, and plateau
From the video we watched, name the five oceans.
Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean, Southern Ocean
What are some factors that causes changes on the Earth's surface?
Natural disasters, weathering, erosion, and deposition, plate movement, etc.
Is the inner core solid or liquid, and what is it made of?
It is solid and made up of mostly iron and nickel.
Explain how weathering, erosion, and deposition work together to change our landscape.
Rocks get broken down by weathering, moved through erosion, and deposited, or dropped, somewhere else through deposition.
What is a peninsula?
A peninsula is an area of land surrounded on three sides by water.
What are the names of the seven continents?
Africa, Antarctica, Asia, Australia, Europe, North America, South America.
What are some different ways that landforms are created? Try to think of two different ways
Flooding rivers leaving sediment (deltas), Moving water (canyons, valleys), blocks of rock pushed up along cracks in the Earth's crust (mountains), water flowing slowly enough to fill up an area (lakes), volcanic eruption and cooling (volcanoes, mountains), volcanic eruption and cooling in the water (islands), wind erosion and deposition (sand dunes), tectonic plate movement pushing up the earth (mountains, hills), etc.
