Sudden Changes to Earth
Weathering and Erosion
Main Idea & Details
Critical Thinking
100
large bodies of salt water
What are Oceans?
100
A sudden movement of the rocks that make up Earth's crust
What is an earthquake?
100
The breaking down of rocks into smaller pieces
What is weathering?
100
How is the ocean floor like the land of the continents?
The land below the ocean's surface has features similar to those above the water.
100
Found on the abyssal plain
What are rocks, remains of dead plants and animals that drift to the bottom?
200
Great areas of land on Earth
What are continents?
200
a mountain that builds up around an opening in Earth's crust
What is a volcano?
200
The movement of weathered rock
What is erosion?
200
When huge slabs of rock in Earth's crust move
What is an earthquake?
200
You drop a pebble in water. How is what happens to the water similar to what happens to the crust during an earthquake?
The water moves in waves in all directions like vibrations from an Earthquake do.
300
The center of the Earth that is the deepest and hottest layer.
What is the core?
300
Melted rock located in the mantle and crust
What is magma?
300
a mass of ice that moves slowly across the land
What is a glacier?
300
The ocean floor feature that begins at the coast
What is the continental shelf?
300
When water flowing over the surface slows down, what happens to the rocks carried by the water?
The rocks are dropped or deposited
400
The Earth's thinnest and coolest layer.
What is the crust?
400
Melted rock that flows onto land
What is lava?
400
the dropping off of weathered rock
What is deposition?
400
Three things a volcano can erupt
What is gas, lava, or ash?
400
How can plants and animals cause weathering?
The roots of plants split rocks apart. Animals can uncover rocks while digging in the ground. Once uncovered, the rocks begin to weather.
500
The layer below the crust
What is the mantle?
500
The rapid movement of rocks and soil down a hill
What is a landslide?
500
Any four causes of weathering
What is running water, wind, rain, or temperature changes?
500
Forces that can move rocks on Earth's surface
What is moving water, wind, ice, or gravity?
500
What happens to an object that is left outside, exposed to rain, snow, sunlight, and freezing temperatures?
It could become worn, rusted, or faded, depending on what it is made of.
