What lunar phase is it when the right side of the moon is exactly half full?
What is a first quarter moon?
The greenhouse gas that humans have emitted that is causing climate change
What is carbon dioxide (CO2)
Why aren't earths mineral and fossil fuel resources spread evenly around the planet?
What is billions of years of geology and plate tectonics
How do relative and absolute dating differ?
Relative is an approximate age of a rock or fossil based on its location in the crust, while absolute dating is finding the exact age using technology (also called radioactive dating and carbon dating).
The moon phase during a Solar Eclipse?
What is a new moon?
What happens when a cold front meets a warm front?
What is warm air that is less dense rises up and possibly causes precipitation?
About how many galaxies are in the observable universe?
200,000,000,000 - two hundred billion!
Explain the difference between a comet, asteroid, meteoroid, meteor and meteorite.
What is:
1. Comet - ball of dust and ice with a tail melting behind it
2. Asteroid - big space rock
3. Meteoroid - small space rock
4. meteor - entering Earth's atmosphere and burning up (think shooting star)
5. meteorite - a meteor that is big enough to land on Earth's surface.
What is weathering breaks rocks into smaller pieces, while erosion carries them away?
Explain two pieces of evidence that scientists use to show that tectonic plates have moved long distances over time.
What could be:
1. Continents fit together like puzzle pieces...
2. Fossils line up...
3. Rock types match up...
4. Glacial striations line up...
5. Mountain ranges line up...
6. Coal (made in tropical locations) found in Antarctica...
7. Age of sea-floor at mid ocean ridge
Which weather front causes large thunderstorms?
What is a cold front?
Explain the difference between mechanical and chemical weathering?
What is:
mechanical weathering breaks rocks into smaller pieces, but they remain the same kind of rock
chemical weathering rearranges the atoms and creates a new type of rock or substance
How do scientists "predict" geologic events like Earthquakes and Volcanoes?
What is using patterns from the past to predict the events in the future?
***IMPORTANT NOTE - Scientists can NEVER predict exactly when these events will occur - just use past data to predict future ones.
What type of weather could you expect when atmospheric pressure is high?
What is sunny and blue skies?
What will happen when oceanic crust converges with land crust?
What is a subduction zone?
