the source of energy is gravity. |
|
|
What causes the Coriolis effect? |
the result of Earth's rotation on weather patterns and ocean currents |
|
|
How does the Coriolis effect change the patterns of wind and water? |
it makes storms swirl clockwise is the southern and counterclockwise in the northern |
|
|
What is the difference between weather and climate? |
the difference between them is the measure of time, the weather is the conditions of the atmosphere over a period of time. climate is how the atmospheres behavior over a long period of time. |
|
|
What factor(s) change the density of water? |
salinity and decreasing temperatures. |
|
|
What do increases levels of GHG in the atmosphere result in? |
carbon dioxide, methane, nitrous oxide, and water vapor gases all help trap heat in earth's atmosphere that increase GHG |
|
|
What is a sink for Carbon Dioxide? |
ocean, plants, and soil |
|
|
What is a sink for Methane? |
soil |
|
|
What is a source of water vapor? |
can be produced from the evaporation or boiling of liquid water or sublimation of ice. |
|
|
What is the luster of a mineral? |
luster refers to how the light is reflected from the surface of a mineralmetallic and nonmetallic are two main types of luster |
|
|
The ratio of a minerals mass to its volume is known as what? |
density |
|
|
What is the difference between a rock and a mineral? |
a mineral is naturally occurring. a rock is one or more minerals. |
|
|
What type of rocks are fossils generally found in? |
sedimentary |
|
|
What is the difference between convergent, divergent and transform tectonic plate boundaries? |
convergent is coming together, divergent is separating, transform is when two plates slide past each other. |
|
|
What direction do heated materials travel? |
no particular direction |
|
|
What is a hot spot? What do they form? |
small area or region with a hot temperature in comparison to the surrounding. they form volcanic hot spots in an area in the mantle from which heat rising as a thermal plume from deep in the earth |
|
|
What causes Earthquakes? Where are they most common? |
a shift in the tectonic plates. most common around fault zones. |
|
|
What is the difference between an epicenter and a focus? |
an epicenter is directly above the focus on earth. the focus is where seismic waves originate below earth's surface. |
|
|
What characteristic of lava determines the violence of the eruption? |
the Viscosity. |
|
|
What is the difference between lava and magma? |
lava is what comes out the volcano. magma is what is still inside the volcano. |
|
|
How do we determine the hardness of minerals? |
measured by the resistance of a hard object |
|
|
What two properties are unique to water in it’s natural state? |
has a high specific heat capacity. has a strong surface tension. |
|
|
How do jetties and breakwater systems change local currents? |
they alter the effects of ocean waves, currents and sand movement. |
