and volcanoes
An underground hot spring that periodically erupts, shooting hot water and steam into the air.
Pg. 122, 40
Rocks are created, destroyed, and recreated in a continuous cycle.
Chapter 6
What is the rock cycle?
Earths crust and part of the mantle are broken into sections that slowly move.
Chapter 2
What is the theory of plate tectonics?
The process of breaking down rock into smaller pieces through wind, water, and sun.
What is weathering?
An underwater volcano that forms wherever magma is erupting through oceanic crust.
Chapter 9
What is a seamount?
A naturally flowing source of hot water.
Pg. 122, 40
What are hot springs?
A rock that forms when magma cools and solidifies.
Chapter 6
What is an igneous rock?
These can move apart, collide, and slide sideways past one another.
Chapter 2
What are tectonic plates?
The movement of sediments to new locations.
What is erosion?
An underwater mountain. This occurs when magma erupts through huge cracks in Earth’s crust as lava.
Chapter 9
What is a mid-ocean ridge?
A type of volcano that is considered active but hasn't erupted in a very long time.
Pg. 35
What is a dormant volcano?
A rock that is made of sediments that have been naturally compacted and cemented together.
Chapter 6
What is sedimentary rock?
A crack in Earths crust.
Pg. 121
What is a fault?
The process that breaks rocks into smaller rocks without changing the minerals they contain.
Chapter 7
What is physical weathering?
A narrow, extremely deep valley. This occurs when the seafloor dips down as one tectonic plate slides under another.
Chapter 9
What is an ocean trench?
A type of volcano that has not erupted for at least 10,000 years and is not likely to erupt again.
Pg. 35
What is an extinct volcano?
A rock that forms when minerals are altered due to extreme heat and pressure.
Chapter 6
What is metamorphic rock?
This person came up with the continental drift hypothesis.
Chapter 1
Who is Alfred Wegener?
The process that breaks rocks into smaller rocks by changing the minerals they contain.
Chapter 7
What is chemical weathering?
These mountains form when gigantic blocks of rocks move up and down along faults.
What is a fault block mountain?
All of these form along plate boundaries and above hot spots.
Chapter 4
What are geysers, volcanoes, and hot springs?
A naturally occurring non-living solid made of minerals.
What is a rock?
The same rocks and fossils were found on opposite sides of the world, concluding that all continents were once joined as Pangea.
Chapter 2
What is the continental drift hypothesis?
The Colorado River shaped the Grand Canyon by this process.
What is weathering and erosion?
These mountains generally form when magma pushes upward into Earth’s crust from the mantle and cools into igneous rock underground, causing the crust above it to bulge. These usually occur as isolated mountains on otherwise flat plains.
What are dome mountains?
