Cryosphere/volcanoes

Question 1

artic

Answer 1

artic ocean surrounded by land

Question 2

antartic

Answer 2

land surrounded by ocean

Question 3

causes of ice sheet growth

Answer 3

weak seasons so less sun in summer, low tilt, high eccentricity, aphelion in N hem summer, amount of insolation at 65N tells if there will be ice sheets in winter

Question 4

how volcanoes affect climate

Answer 4

violent eruptions erupt to stratosphere and wind takes ash across hemisphere it is in, ash absorbs sunlight and area below is cooler

Question 5

tropical volcanoes

Answer 5

more severe as can go in both hemispheres and cuts off more sun at equator

Question 6

high latitude volcanoes

Answer 6

not as severe as dont cut off as much sun

Question 7

criteria for volcanoes to change climate

Answer 7

violent eruption at equator and needs to reach both hemisphere

Question 8

orogeny

Answer 8

increases upland area which increases snow and more radiation reflected and area cools

Question 9

continental drift

Answer 9

dictates land to ocean ratio/where land and ocean is

Question 10

main driver of radiative forcing

Answer 10

anthropogenic

Question 11

dvi

Answer 11

dust veil index

Question 12

why are sunspots hard to quantify

Answer 12

cycles irregular, hard to measure. surrounded by hot faculae
