100
This process that happens in the asthenosphere that causes crustal plates to move around.
What is convection?
100
These two processes break down rock to turn it into sediment.
What are weathering and erosion?
100
This igneous rock is black and glassy.
What is obsidian?
100
Sedimentary rocks form in these low areas that are shaped like sinks.
What are basins?
100
Igneous rock can be changed into a sedimentary rock through these four processes.
What are weathering, erosion, deposition and cementation?
200
Plates coming together often results in this type of landform.
What is a mountain?
200
Sedimentary rocks are the only kind of rocks which can contain these remains of ancient life.
What are fossils?
200
This igneous environment forms larger crystals from magma.
What is intrusive?
200
Rock layers that form at low elevations can be pushed to high elevations through this process.
What is uplift?
200
Sedimentary rock can be changed into a metamorphic rock through these two processes.
What are heat and pressure?
300
This Principle states that all rock layers were deposited horizontally.
What is the Principle of Original Horizontality?
300
A rock that fizzes and contains fossils indicates that its sediments were deposited in this kind of environment:
What is an oceanic environment?
300
This igneous environment forms small crystals from lava.
What is extrusive?
300
This type of fossil can be used to help a geologist tell the relative ages of the layers of sedimentary rocks.
What is an index fossil?
300
Igneous rock can be changed into a metamorphic rock through these two processes.
What are heat and pressure?
400
Explain how tropical ocean fossils can exist in the Kaibab layer (at the top) of the Grand Canyon (3 part explanation)
What are deposition, cementation, uplift?
400
This Principle states that the oldest rock layers were deposited first (on the bottom) and the youngest layers were deposited last (on the top).
What is Superposition?
400
This type of igneous rock is intrusive and is the source rock for gneiss.
What is granite?
400
A rock layer can be pushed deep into the upper mantle by this process.
What is subduction?
400
Metamorphic rock can be changed into a sedimentary rock through these four processes.
What are weathering, erosion, deposition and cementation?
500
The size order in which sediments will be deposited as a stream flows towards a basin
What is largest first, medium, then smallest?
500
Soil is formed by these 3 processes:
What are weathering, deposition and decomposition?
500
This type of weathering explains why the igneous rock of a dome mountain is left behind when the softer sedimentary rock is eroded away.
What is differential weathering?
500
In the picture shown, which part of the rock is younger?
Explain.
What is the pink granite?
500
Sedimentary rock can be changed into an igneous rock through these two processes.
What are melting and recrystallization?
