Plate tectonics
The three types of plate boundaries.
What are Convergent, Divergent, Transform
This type of mineral is one that contains a metal in extractable concentrations. Ex. Hematite is a ______ mineral of iron.
What is Ore
The main hazard associated with shield volcanoes is ________.
What are Lava flows
Occurs when wind, water or ice loose energy.
What is sediment deposition?
The four inner planets in our solar system are made of these types of materials, which melt at very high temperatures.
What are refractory materials?
A mid-ocean ridge would be found along this type of plate boundary.
What is Divergent?
These two fossil fuels form from alteration of kerogen at different temperatures and pressures within the earth.
What are petroleum and natural gas?
3 things that are required for LIQUEFACTION to occur.
What are Earthquakes, loose ground material, pores saturated with water
This shape of valley is carved by movement of a glacier, as opposed the the V shaped valleys carved by rivers.
What is a U shaped valley?
These layers are formed when a rock containing platey minerals is metamorphosed under directed pressure.
What is foliation?
The type of plate boundary where stratovolcanoes are found
What is Convergent
The largest supply of liquid fresh water is found as this.
What is Groundwater?
A type of mudflow and also a volcanic hazard caused by melting ice mixing with ash during a volcanic eruption.
What is a lahar?
Conglomerates are formed where sediment is deposited by this type of stream.
What is a braided stream?
These types of volcanoes aren't dangerous, as long as you get out of the way of their main hazard, lava flows.
What are shield volcanoes?
The Himalayas are forming where these two types of crust are converging.
What is Continental and Continental
The food you eat depends on this natural resource, which can be altered by desertification, overgrazing, and poor crop management.
What is soil?
A tsunami typically forms along this type of plate boundary, when seawater is displaced by movement of the subducting and overriding plates.
What is a convergent plate boundary?
This type of continental margin is wide and flat, and characterized by coasts with barrier islands, beaches, and spits.
What is a passive margin?
This rock forms when tiny marine microorganisms die and their calcite shells build up on the sea floor. (Be specific!)
What is chalk?
This type of plate boundary is NOT associated with volcanism.
What is Transform
These sedimentary rocks are valuable for making drywall and table salt, and their name sounds a lot like how they form.
What are evaporite minerals?
Floods of this size have a 1% chance of occurring in a given year.
What is a 100-year flood?
This rock is named for being out of place, due to deposition miles from its source rock by a glacier.
What is a glacial erratic?
This geologic feature can be formed along a normal fault or at a landslide called a slump, where one side moves down relative to the other, leaving a step.
What is a scarp?
