Earthquakes create these. They cause the ground to shake, travel through the earth, and can be detected by seismometers.
What are seismic waves?
In areas with effusive eruptions, this type of volcano forms.
What is a shield volcano?
The part of the world we live on.
What is the crust? (which is also part of the lithosphere)
This is the transport of broken down materials to another location.
What is erosion?
Locations of the two largest ice sheets on earth.
What is Antarctica and Greenland?
The average time between earthquakes at a location.
What is the recurrence interval?
Near shield volcanoes you may see some of these small volcano shaped structures.
What are cinder cones?
These are the 3 types of rocks.
What is sedimentary, metamorphic, and igneous?
These are mineral deposits made inside caves or caverns.
What are speleothems? (Also accept dripstones, stalactites, stalagmites).
Snow that falls on a glacier will turn into this before it changes to ice.
What is firn?
The 3 types of sedimentary rocks.
What are clastic, chemical and biogenic?
The difference between lava and magma.
What is magma is molten rock inside the earth, lava is molten rock on the surface?
Underwater mountain chains that develop at diverging plate boundaries.
What are mid ocean ridges?
This is a physical weathering process where layers of the rock will peel off in sheets.
What is exfoliation?
As glaciers retreat from valleys, sea water can move in.
What is a fjord?
This is a ocean inlet or narrow sea or ocean channel between two bodies of land.
What is a sound?
In this deadly volcanic hazard, hot ash and gas flow down the side of the volcano. Lava bombs are also a threat.
What is pyroclastic flow?
When loose sediment (such as sand) turns into a rock (such as sandstone)
What is lithification?
These environments speed up the chemical weathering process.
What are wetter, warmer environments?
Eroded debris that is dropped at the glaciers farthest extent.
What is a terminal moraine?
The percentage of dissolved solids in the ocean.
What is salinity?
This type of lava has a high viscosity, erupts explosively from continental hot spots.
What is rholitic?
The type of convergent boundary that does not produce a subduction zone.
What is the convergence of a continental plate with a continental plate?
Name two types of chemical weathering processes
What are oxidation, hydrolosis, carbonation
In areas between an annual average temperature of 19 degrees and 30.5 degrees, ground that does not uniformly freeze is called:
What is discontinuous permafrost?
