Plate Techtonics
Outer Techtonics
Mantle Theorem
Layered Theorem
Plate Techtonics
Plate Techtonics states that the Earth's outer shell is divided into several plates that glide over the mantle.
Example Question #2 : 7th Grade Science
Select the outer most layer of the Earth.
Outer Core
Crust
Inner Core
Mantle

Example Question #3 : 7th Grade Science
What type of rock could be made out of sand and shells?
Igneous
Sedimentary
Igneous and Sedimentary
Metamorphic
Sedimentary
Both sand and shells are small materials. A sedimentary rock is formed from small materials, such as sand and shells; thus, sedimentary is the correct answer.
Example Question #4 : 7th Grade Science
Select the main difference between the three types of rocks: sedimentary, metamorphic, and igneous.
The age of the rocks
The texture of the rocks
Where the rocks can be found
How the rocks are formed
How the rocks are formed
The main difference between the types of rocks is how the rocks are formed.
Sedimentary rocks are formed from small particles of materials, such as sand or pebbles.
Metamorphic rocks are formed from changes in heat and pressure under the earth's surface.
Igneous rocks are formed from magna cooling and hardening.
