Question 1

Layers of the atmosphere

Answer 1

trophosphere, stratosphere, mesosphere, thermosphere, exosphere

Question 2

features of the trophosphere

Answer 2

lowest layer, temp decreases at a constant rate as altitude increases.

Question 3

features of stratosphere

Answer 3

layer of atmosphere that is above the trophosphere where temp increases as alt increases

Question 4

features of mesophere

Answer 4

the strong lower part of the mantle between the asthenosphere and the outer core. also the layer of the atmosphere between strato and thermo and in which temp decreases as alt increases

Question 5

thermosphere features

Answer 5

the uppermost layer of the atmosphere, in which temperature increases as altitude increases

Question 6

exosphere features

Answer 6

particles are incredibly spread out, no air to breathe, cold.

Question 7

how eccentricity and obliquity contirbute to the Milankovitch Effect.

Answer 7

promote more extreme variation in irradiation of the northern hemisphere and less extreme variation in the south.

Question 8

how specific heat affects wind + pressure

Answer 8

heating (or cooling) of a column of air leads to horizontal differences in pressure, generating a pressure gradient force which causes the air to move and a circulation to develop.

Question 9

low pressure

Answer 9

cloudy

Question 10

ocean current and how it is formed

Answer 10

a

Question 11

how do seismotologists figure out the epicenter of an earthquake

Answer 11

s-p time method. seismograms of same earthquake from different locations. time-distance graph. distance by reading horizontal axis. then locate epicenter.

Question 12

wegners four pieces of evidence

Answer 12

fossils, mountain comp, oil in non tropical areas, puzzle pieces

Question 13

200 million year old rocks

Answer 13

none because they get recycled through subduction

Question 14

how there is magentic evidence contained in rocks showing how Earth’s magnetic poles have flipped throughout time.

Answer 14

lava lines up with north pole.

Question 15

relative speed of waves

Answer 15

p, s, l

Question 16

lithosphere

Answer 16

crust + uppermost mantle

Question 17

asthenosphere

Answer 17

upper layer of mantle, below litho.

Question 18

outer core

Answer 18

liquid. mostly iron and nickel

Question 19

inner core

Answer 19

solid ball, mostly iron and nickel.

Question 20

Despite there being plenty of evidence supporting Wegener’s theory, he couldn’t correctly explain how the continents were moving. His ideas didn’t match many widely spread ideas, like the idea that animals used stepping stone islands, land bridges, or floated across the ocean on a log to get from place to place.

Answer 20

yeah

Question 21

shadow zone

Answer 21

The shadow zone is an area that does not receive any P-waves because S-waves are stopped by the liquid outer core, as they can not travel through liquids, and P-waves are bend around it.
