Why do we experience seasons on Earth?
-Earth's tilt
-Earth's Revolution
100
When did Earth and our solar system form?
4.6 Billion years ago
100
What lunar phase is it when the right side of the moon is exactly half full? 
What is a quarter moon?
100
The greenhouse gas that humans have emitted that is causing climate change
What is carbon dioxide (CO2)
100
The theory that explains that the continents have moved over millions of years
What is plate tectonics
200
A star's lifespan and life cycle is dependent on what factor?
A star's mass
200
What evidence supports continental drift?
-Matching coastlines, fossils, climate evidence, rock formations
200
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).
200
The moon phase during a Solar Eclipse?
What is a new moon?
200
What happens when a cold front meets a warm front?
What is warm air that is less dense rises up and possibly causes precipitation?
300
This occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth in what we see as a New Moon.
What is a solar eclipse?
300
A sample contains 25% of its original radioactive parent isotope. How many half-lives have occured?
Two
300
About how many galaxies are in the observable universe?
200,000,000,000 - two hundred billion!
300
What are two factors affecting the amount of gravity?
What are distance and mass?
300
Explain the difference between weathering and erosion
What is weathering breaks rocks into smaller pieces, while erosion carries them away?
400
Why do we see the same side of the moon from earth?
The moons period of rotation is equal to its period of revolution.
400
What principle states that younger rock layers are usually found above older layers?
Law of Superposition
400
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
400
Which weather front causes large thunderstorms?
What is a cold front?
400
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
500
What evidence supports the Big Bang Theory?
-Redshift of galaxies
-Cosmic microwave background radiation
-Abundance of hydrogen and helium
500
What can the study of meteorites tell us about the early solar system?
The study of meteorites can tell us about the early solar system by revealing the composition and structure of the materials that formed the planets.
500
Type of boundary that causes earthquakes
What is transform?
500
What type of weather could you expect when atmospheric pressure is high?
What is sunny and blue skies?
500
What will happen when oceanic crust converges with land crust?
What is a subduction zone?
