100
The layer of the earth above the core.
What is the mantle?
100
The top layer of the earth, above the mantle.
What is the crust?
100
The center part of the earth made of nickel and iron.
What is the core?
100
The rigid outer shell of the earth.
What is the lithosphere?
100
The water part of the earth's surface.
What is the hydrosphere?
200
The moving of weathered rock and soil
What is erosion?
200
A natural, nonliving solid with a definite chemical structure.
What is a mineral?
200
The process that breaks down and changes rocks.
What is weathering?
200
The layer of gases that surrounds the earth and contains the clouds.
What is the atmosphere?
200
Large sections of the earth's surface made of the crust and the rigid top part of the mantle.
What is a plate?
300
The dropping of materials moved by erosion.
What is deposition?
300
This theory explains how continents move.
What is plate tectonics?
300
The rock formed from melted rock that comes from deep within the earth.
What is igneous rock?
300
Rock formed when sediments are pressed or cemented together.
What is sedimentary rock?
300
The way that rocks change from one form to another.
What is the rock cycle?
400
Rock formed when igneous or sedimentary rock is changed by heat or pressure.
What is metamorphic rock?
400
Weathered igneous rock
What is sand?
400
These are classified by the way they are formed.
What are rocks?
400
These cause earthquakes, volcanic eruptions, and mountain formations.
What are plate movements?
400
The remains of any dead organisms.
What are fossils?
500
This is a continuous process.
What is the rock cycle?
500
People build homes, cities, and farms on this.
What is the lithosphere?
500
This breaks the rocks apart, but it doesn't change what they are made of.
What is physical weathering?
500
This changes the sbustance that makes up rocks.
What is chemical weathering?
500
This lead scientists to hypothesize that the continents have moved.
What is shape evidence, fossil evidence, glacier evidence, coal evidence, and mountain evidence?
