15 degrees C

- How far down is 2km into the earth? (what part?)
- How far down is 10km into the earth? (what part?)
- What is a scientific theory?
A substantiated explanation of natural phenomena based off of repeatable, testable experiments.
- How do scientific theories change?
Only in the face of evidence, collected by new experiments
- What is leeward?
Drier side of the mountain, with wind moving away from the mountain.
- What is windward?
Wetter side of the mountain, with wind moving toward the mountain.
- How can we get air to cool and rain?
Lift it to it's LCL, allowing it to cool to its dew point.
- What can s-waves travel through?
Everything but liquid
- What can p-waves travel through?
- A seismic station is 5000km away from an epicenter. The P wave arrives at 1:30pm. What time did the S wave arrive?
- A P wave arrives at 1:45am. An S wave arrives 7 minutes later. How far away is the station from the earthquake?
- What is an igneous rock?
A crystalline solid formed from the cooling and hardening of magma and made up of more than one mineral
- What are vesicles?
- What is a sedimentary rock?
Sediments that have been cemented together
- What is a metamorphic rock?
Rock that has been made through intense pressure and heat
- What is rock gypsum?
A chemically precipitated sedimentary rock
- How old is the universe?
- How old is the solar system?
- What does mafic mean?
Denser, hotter, extrusive, darker rock properties
- What does felsic mean?
Less dense, cooler, intrusive, lighter rock properties
- What time of the year would the insolation be the highest in Vermont?
During the summer
- Why is the north pole cold?
Low angle of insolation
- How can climate change slowly?
Through differences in precision and the movement of plates
- What is the temperature of the Earth’s core?
- What is the temperature of the Earth’s mantle? (give a range)
- What is fracture?
Uneven, rough breakage
- What is cleavage?
Even, flat breaks in planes
- What is streak?
The color of the mineral that is left behind on a plate after it has been ground
- What is hardness?
Whether a mineral gets scratched or does the scratching
- Which wave has the shortest wave length in the visible spectrum?
- Which wave has the longest wave length in the visible spectrum?
- Is Betelgeuse a main sequence star?
- Is Betelgeuse a blue giant?
- Does Betelgeuse have a high luminosity?
- What is a redshift?
When light waves are moving away from you
- What is a blueshift?
When light waves are moving towards you
- What does wave length have to do with redshifts and blueshifts?
Wave lengths get longer with a redshift and get shorter with a blueshift
- What features can we find at divergent plate boundaries?
Mid ocean ridges
- What features can we find at convergenc plate boundaries?
Subduction zones and trenches
- How do we calssify rocks?
Through texture, rock formation, particle size, chemical make up
- If I have 50 gams of C-14, how many years ago did it have 100 grams of C-14?
- What is an unconformity?
A gap in age in a particular rock formation
- What is the principle of horizontaility?
Layers of rock are layed down, normally, horizontally
- What is the principle of superposition?
Older rock layers are on the bottom, younger on the top
- Which are higher, stratus clouds, altocumulus clouds, stratocumulus clouds, or cirrus clouds?
- What happens to the pressure when you go up a mountain?
- What happens to the pressure when you go down a mountain?
- How can you use patterns to help classify and organize things like rocks and minerals?
By seeing how patterns form, you can classify rocks based on their physical properties. This enables scientists to study them better since they are grouped according to those properties
- Why would studying events and their causes help scientists?
It allows scientists to predict future events and how to better prepare the public. It also allows them to recognize things that are unusual.
- Why should I worry about scaling things down so I can understand them?
It allows us to better study things that are either normally to small to see or too large to comprehend.
- Give an example of how nature likes to keep itself in balance
The mid ocean ridge introduces new rock while the subduction zones recycle old ocean floor. The cycle continues, keeping the age of the ocean crust fairly young when compared to the continent.
- Think about density in space. Are they related? How?
Density is related to mass and volume. The more dense an object is, the more gravitational pull it has, because of the ratio of mass to volume.
