Spheres of Earth
This part of earth's system includes all the rain, lakes, oceans, and streams on earth.
What is the hydrosphere?
The movement of rock, mud, or debris down a slope during heavy rain is this natural disaster.
What is a landslide?
The earth has _____ layers.
4 Layers
This is the movement of bits of land from one place to another by nature.
What is erosion?
These are the piece of land that interlock like a puzzle, covering the core of the Earth.
Tectonic Plates
Animals and plants are part of this sphere on Earth.
What is the biosphere?
This large ocean wave usually is caused by an underwater earthquake or volcanic eruption.
What is a tsunami?
The outermost layer of the earth.
What is the crust?
This happens in a river, when soil is carried downstream and then drops into a new position.
What is deposition?
This geologist theorized that the Earth's land was once one connected piece.
Who is Alfred Wagener
Any landforms that exist on the crust of the earth belong to this sphere.
What is the geosphere?
This is a mountain that opens downward to a pool of molten rock below the earth's surface. Gases, rock, and lava shoot out.
What is a volcano?
Magma is found in this layer of earth.
What is the mantle?
The rubbing action that results in smaller pieces being broken off of a land mass is called this.
What is abrasion?
This plate movement happens when two plates rub against each other, causing earthquakes.
What is a transform movement?
This sphere includes all gases that surround the earth.
What is the atmosphere?
This is a violent rotating column of air that funnels to the ground.
What is a tornado?
Tectonic plates of land are found in this layer of earth.
What is the crust?
The Grand Canyon was caused by this type of erosion.
What is water erosion?
This plate movement occurs when plates push into each other, or collide.
What are convergent plates?
If this sphere did not exist, nothing would survive on Earth.
What are the atmosphere, biosphere, geosphere, and hydrosphere?
This is a rise of water results from fast-falling, heavy rain, carrying homes away.
What is a flood?
The hottest layer of the earth is its center, called this.
A glacier moves down a mountain, dragging rock and soil with it. This kind of erosion is called...
Ice erosion.
Valleys and canyons can be caused by the pulling apart of tectonic plates called this.
What are divergent plates.
