What is the greenhouse effect?
Bad gasses (CO2 and others) are trapped in the atmosphere
True or False: tectonic plates are the same as fault lines
False
What are 3 reasons storms are good (100 points for each answer)
1. Cools off the earth when cooler rain falls (through convection)
2. Cleanses the air of dust, pollen and dirt (these particles help with condensation)
3. Transports water from lakes/seas (evaporation) to dry land (through precipitation)
What is the difference between magma and lava?
Magma is below the earths surface. Lava is when the magma is coming out of the earth's surface
conduction
What tool measures atmospheric pressure?
Barometer
What layer of the earth is involved in Earthquakes?
The crust
Why do so many hurricanes form off the coast of Africa?
There is a large warm air mass
Where is the vent in a volcano?
the opening at the surface of the earth
What is the place called where the earth quakes start?
Focus- the area below the surface of the earth
Epicenter- the area directly above the focus
Explain how convection works
Warm air rises, Cold air falls
a seismometer
what type of cloud does a thunderstorm come from?
Cumulonimbus
Layers of magma and ash building layers. It takes many eruptions to build up the volcano.
How do sinkholes form?
water eats away at limestone bedrock or water washes away areas of dirt and small rocks causing there to be an empty pocket that collapses.
If you are swimming and the sun goes down, would the water get cold quickly or slowly?
Slowly. The land cools down quicker
Where 95% of earthquakes come from?
Movement along fault lines
(partial credit for talking about Tectonic plates)
What is the coreolis effect
Air and wind curving due to the rotation of the earth
describe viscosity
The tendency to resist flow. The slower the flow, the greater the viscosity.
What are 2 things that effects the viscosity of lava?
The temperature
The amount of silica within it
What are the 3 ways heat transfers (with explanation of all)
1. Radiation- heating through air
2. Conduction- heating with direct touch
3. Convection- warm air rising, cold air falling
Tell me things about P & S waves (more points for more information)
P- Primary: compression waves, push and pull, travels fast
S- secondary: transverse waves, side to side waves, travels slower than P waves
How do air masses make an unstable atmosphere?
The warm air mass and the cold air mass meet. Convection on a large scale occurs.
Describe a convergent plate boundary
one piece of land goes under another piece of land.
Volcanoes form at these boundaries
If an earthquake has a magnitude of a 8.7, does that mean it has a high intensity? Why?
