This is the difference between weathering and erosion.
What is weathering breaks rocks down and erosion washes them away?
100
This is how a volcano forms at a plate boundary
What is an oceanic and a continental plate are converging?
100
This type of volcano has alternating quiet and violent eruptions.
What is a composite volcano?
100
These are the two types of lithosphere (crust) on the earth.
What are oceanic and continental?
100
These are two main characteristics of sedimentary rocks.
What are layers and fossils?
200
This is the process changes magma into igneous rock.
What is cooling?
200
This is how a mid ocean ridge forms.
What is when two oceanic plates diverge?
200
This is where ash and material comes out of a volcano.
What is the vent?
200
This is the type of crust that is denser and thinner.
What is oceanic crust?
200
This is what your are testing when you scratch a rock across a porcelain tile.
What is the streak or color of the powder?
300
This is how sedimentary rocks are formed.
What is weathering, deposition (forming layers), and cementation?
300
This is what causes mountains to grow.
What is two continental plates converge?
300
This is the process that occurs in the mantle to move the plates.
What is convection?
300
This is the best unit of measurement when talking about plate movement.
What is centimeters (inches for us Americans)?
300
This size of rock crystals form when magma cools slowly.
What are large crystals?
400
This is how igneous rocks are formed.
What is rock is completely melted?
400
This is how two plates move at a mid ocean ridge.
What is they are moving apart or diverging?
400
This is what has formed the Hawaiian Islands.
What is a hot spot in the middle of a tectonic plate?
400
This is how the outer and inner core are different.
What is the outer core is liquid and the inner core is solid?
400
This size of rock crystals form when lava cools quickly.
What are small crystals form?
500
If Rock B scratches Rock A, this is the rock that is harder.
What is Rock B is harder?
500
This is what happens when subduction occurs.
What is an oceanic plate dives under a continental plate?
500
This is the difference between lava and magma.
What is lava is magma that has come to the Earth's surface?
500
This is what we call the crust and the upper part of the mantle.
What is the lithosphere?
500
These are the two things that cause metamorphic rocks to form.
What are heat and pressure?
