Rocks
How are rocks clasified?
Formation
What are streak and luster?
The color a mineral in powder form and how a mineral interacts with light.
What is weathering
The breaking down of rocks by chemical and/or physical means
convection currents?
What are the 2 types of natural resources?
How are igneous rocks formed?
The cooling and solidification of magma or lava
What scale measures mineral hardness
Moe's Hardness Scale
What is erosion
The movement or transportation of sediment and/or rocks from water, wind, gravity, and ice
What makes convection currents possible?
What is a downside of burning fossil fuels?
Carbon Dioxide Emissions
The deposition, compaction, and cementation of sediment. (D.C.C.)
What is the hardest mineral?
Diamond
What is deposition
The deposition of sediment
What are convergent plate boundaries
When 2 plates collide towards each other
Is nuclear fuels considered renewable or non-renewable?
Non-Renewable
Why is color an unreliable way to determine minerals?
There are many minerals that look alike like gold and pyrite.
How are deltas formed
Deposition
What are divergent boundaries
What global warming?
The higher average trend of global temperatures as a result of the greenhouse effect.
What is the difference between intrusive and extrusive igneous rocks?
Intrusive rocks are formed inside the earth by magma while extrusive rocks are formed on the surface by lava. Intrusive rocks have larger crystals inside them since they cooled slowly. Extrusive rocks sometimes have air pockets since they cooled quickly.
What are the classifications for minerals?
Inorganic, solid, naturally occurring, definite chemical composition, and crystalline structure
What is abrasion
The grinding or wearing away of rocks
What is a transform boundary?
When 2 plates move parallel from each other, often resulting in earthquakes and fault lines.
What are the downsides of global warming?
