The Crust
When two plates that make up the crust drift away from each other.
What is a divergent plate boundary?
When an undersea volcano grows so tall that it breaches the ocean's surface, thereby forming new land.
What is an island?
When the Earth's crust moves and causes seismic waves and shaking?
What is an earthquake?
Underground liquid rock.
What is magma?
Ancient, gigantic masses of ice that cause erosion and deposition.
What are glaciers?
The plate boundary type found in the Bay Area.
What is transformation boundary?
The most common type of volcano.
Melted rock above ground.
What is lava?
When landforms are worn away and sediment is moved to new places.
What is erosion?
The supercontinent that contained all current continents.
What is Pangaea?
Composite volcanoes are common above which plate boundary?
What is convergent plate boundary?
The volcano with the fastest moving lava.
What is a shield volcano?
A giant wave caused by an earthquake that destroys coastline.
What is a tsunami?
The layer of the Earth whose currents cause the crust to move.
What is the mantle?
A rupture in the crust of a planetary body that causes substances such as gases, ash, and molten rock to erupt to the surface through a vent.
What is a volcano?
The scientific theory that the crust is made up of several plates that are moving due to the movement of the mantel.
What is Plate Tectonic Theory?
The ring that wraps around the Pacific Ocean, moving along South East and East Asian, above the Pacific, and along the West Coast of the United States.
What is the Ring of Fire?
When a volcano spews gas, lava, and volcanic bombs.
What is an eruption?
The name for the type of matter deposited in the process of deposition.
What is sediment?
Oceans, rivers, streams, lakes, and ponds in the water cycle.
What are collection?
The process that is undergone by the denser plate at a convergent plate boundary.
What is subduction?
The space where magma builds up and is stored before it travels up the channel and out the vent of a volcano.
What is a magma chamber?
Roots or ice can cause a rock to quickly split or fracture in this process.
What is weathering?
Water flows in recognizable patterns. This can impact climate, weather, and the placement of sediment.
What are water currents?
The phase of the water cycle that causes erosion by water traveling downhill.
What is runoff?
