A
solar, lunar, internal, thermal/energy
2
Q
- Match the heat transfer process with the analogy: A. Conduction 1. Bucket line from river to Granny’s house. B. Convection 2. Each helper carries their own bucket. C. Radiation 3. Hose pumped at the river.
A
A. conduction-bucket line from river to grannys house
B. convection-each helper carries their own bucket
C. Radiation-Hose pumped at the river
3
Q
- How does most of the heat from a campfire reach you?
A
Radiation
4
Q
- What are the 4 geologic processes shaping the surface?
A
erosion, plate techtonics, volcanoes, impact craters and even humans
5
Q
- About how many times bigger is the crater than the impactor?
A
8 times or 10 times greater
6
Q
- Why is there so little erosion on other terrestrial planets?
A
no liquid water
7
Q
- What are the 3 kinds of rocks?
A
igneous. metamorphic and sedmentary
8
Q
- Who first proposed continental drift?
A
Aford wagner
9
Q
- Why wasn’t continental drift accepted more quickly by
geologists?
A
He was a weather man
10
Q
- Give a geographical example (a specific place) on Earth of A) a zone of convergence: B) a zone of divergence: C) a transform fault: D) a hot spot:
A
A. a zone of convergance-rocky mountains
B. a zone of Divergance-grand canyon
C. a transform fault- San andreas
a hotspot-hawaii or yellowstone
11
Q
- The Earth’s continental crust is mostly made of what kind of igneous rock? How about the Earth’s oceanic crust?
A
Granitic
12
Q
- What was the original atmosphere of Earth? The secondary atmosphere (from outgassing)
A
- methane, water and nmaonia
2. carbon dioxcide, water and nitrogen
13
Q
- Where did the oxygen in Earth’s atmosphere come from?
A
plants/photosynthesis
14
Q
- Noting that Venus has 100× Earth’s atmosphere, which has more atmospheric N (Earth or Venus)? More atmospheric H2O?
A
venus, earth
15
Q
- Firing a long range artillery shell south towards the equator which way should you point? (Hint: your target is moving faster eastward than you are).
A
east
16
Q
- Which kind of interior seismic wave (S or P) DOES propagate through fluids and is faster?
A
p is faster and S is slower
17
Q
- Why do surface seismic waves cause the most property damage?
A
because the property is on the surface
18
Q
- Why does Earth’s air temp gradient have an extra zig-zag?
A
ozone layer
19
Q
- What’s the expected consequence of the loss of the ozone layer? Of increased greenhouse effect gases?
A
- more uv radiation
2. warmer tempature
20
Q
- Since Jupiter spins faster than Earth would you expect more or less convection cells than Earth?
A
more convection
