3.1
True
What makes up the geosphere?
3.1
soil, rock, and metal that are broken down to smaller particles.
Naturally occurring, inorganic solids that have crystal structures and definite chemical compositions is called ____.
3.1
Minerals
To be considered as a mineral it needs 5 characteristics which are______.
3.1
color, streak, hardness, luster, and crystal shape
Solid composed of minerals and sometimes other materials such as organic matter is what?
3.1
rock
How do scientists classify rocks?
3.1
how they are formed
What are the 3 main types of rock?
3.1
igneous, sedimentary, and metamorphic
This rock is formed by molten material or magma.
3.1
igneous rock
This rock is formed when forces such as water, wind, and ice break down rocks into smaller pieces.
3.1
sedimentary
This rock is formed when extreme temperatures are pressure within the Earth’s change existing rock to new rocks. (They change structure.)
3.1
metamorphic rock
The 3 layers that make up the geosphere are ____
3.1
crust, mantle, and core
This is the brittle layer outer layer of the geosphere.
3.1
Crust
The middle and largest layer of the geosphere. Made out of rock and is hotter and denser causing the rocks to flow.
3.1
Mantle
