Earth's Interior
This is the thinnest layer of Earth's interior.
The Mohs Hardness Scale is a range of what numbers?
1-10
Igneous, Sedimentary, Metamorphic
This is a series of processes that slowly change rocks from one kind to another.
The Rock Cycle
Geology....
Rocks
This part of Earth's interior has two distinct parts.
The core
Metallic, glassy, earthy, and pearly describe a minerals what?
Luster
What process acts on Earth's surface to break rocks into pieces?
Weathering and Erosion
How do rocks become magma?
Melting
The oceanic crust is primarily composed of this rock.
Basalt
This layer of Earth's interior is liquid.
Outer Core
The color of its powder describes a minerals what?
Streak
Metamorphic rocks form through changes of what?
Heat and Pressure
Sediment
The continental crust is primarily composed of this rock.
Granite
Rock samples are a form of what kind of evidence?
Direct Evidence
Why do diamonds only form in certain parts of the mantle?
Diamonds require intense pressure and temperature to form.
Igneous rocks form through the cooling of what?
Magma and lava
How does a rock turn into sediment?
Weathering and Erosion
The lithosphere and asthenosphere are located in this layer of the Earth
Upper Mantle
What occurs when earthquakes happen?
Seismic Waves
To be classified as a mineral, an object has to these five characteristics
Naturally Occurring
Solid
Formed by Inorganic Processes
Crystal Structure
Chemical Composition
This is the final stage of sedimentary rocks forming
Cementation
These slowly move over Earth's surface and helps drive the Rock Cycle
Plate Tectonics
Heat in the core and the mantle cause these to form which help cycle material on Earth.
Convection Currents
