Layers of the Earth
This layer of the Earth is the densest and found in the center.
What is the inner core?
The plate boundary that two plates slide past each other
What is transform boundary?
List the Geologic Lengths of time in order from largest to smallest.
What is Eon, Era, Period, Epoch?
This type of rock forms after sediments go through deposition, compaction, and cementation.
What are sedimentary rocks?
What is less than?
This sphere is made up of the bottom part of the crust and top part of the mantle.
What is the lithosphere?
The plate boundary that collides into each other
What is Convergent boundary?
The Earth is this many years old
What is 4.6 BILLION years old?
No matter the rock type once it is uplifted it goes through this process to become sediments
What is weathering and erosion?
This property of a mineral is determined by rubbing the mineral across a plate to see what color is left
What is streak?
All living things are part of this sphere of Earth.
What is Biosphere?
Because of this movement happening in the mantle, we have plate movement
What are convection currents?
Fish, Reptiles, and Amphibians first evolved in this era
What is the Paleozoic Era?
Igneous rocks that are cooled on the Earth's surface are this type of Igneous
What is Extrusive?
This property of a mineral is determined by a scale from 1-10 and tests to see which items can scratch it
What is Moh's Hardness Scale?
Because of Earth's magnetic field we can use which tool for travel.
What is a compass?
The theory that helps to prove we started as the supercontinent Pangea and then the plates moved
What is Continental Drift?
The dinosaurs only lived during this era
What is the Mesozoic Era?
Extreme Heat and Pressure create Metamorphic Rocks. The Metamorphic Rocks that have layers are called.
What are Foliated Metamorphic Rocks
1-Talc, 2-Gypsum, 3-Calcite, 4-Flourite, 5-Apatite, 6-Feldspar, 7-Quartz, 8-Topaz, 9-Corundum, 10-Diamond
Steel (6.5) can scratch me, but Apatite (5) cannot. I am this mineral
What is Feldspar?
This layer of Earth is between the crust and the outer core.
What is the Mantle?
This is a slow change that happens at Divergent boundaries underwater
What is Sea-Floor Spreading?
This law states that the oldest rocks are deeper in the Earth and the newest rocks are closest to the surface.
What is the Law of Superposition?
Sedimentary Rocks have three types. This type is made from the crystallization of evaporated water
What are Chemical Sedimentary Rocks?
1-Talc, 2-Gypsum, 3-Calcite, 4-Flourite, 5-Apatite, 6-Feldspar, 7-Quartz, 8-Topaz, 9-Corundum, 10-Diamond
Fluorite can scratch which of these minerals.
What are Talc, Gypsum, and Calcite?
