Question 8

interglacial period

Answer 8

the time in-between glacial periods

Question 9

ice cores

Answer 9

tubes of ice which are drilled out of the ground and show the different levels of carbon dioxide in the air as they air is frozen into the ice

Question 10

fossil records

Answer 10

looking at rocks to see the different features that flora and fauna had adapted to cope with the conditions

Question 11

orbital change

Answer 11

the adaption in the worlds orbit, which can influence the climate of the earth

Question 12

milankovich cycles

Answer 12

cyclical movements related to the earths orbit, there are three: eccentricity, axial tilt and precession

Question 13

sun spots

Answer 13

darker cooler areas of the sun that you can use to map the output of the sun

Question 14

greenhouse effect

Answer 14

this is the natural layer of gases such as CO2, Methane etc which help keep in some of the earths warmth so that species can inhabit the planet

Question 15

enhanced greenhouse effect

Answer 15

this is a much thicker layer of greenhouse gases which have built up due to humans releasing them and are warming the earth by not letting as much heat out and bouncing more of it back to the earth

Question 16

methane

Answer 16

a greenhouse gas released when cows fart or rice rots

Question 17

nitrous oxide

Answer 17

another greenhouse gas released in industries

Question 18

carbon dioxide

Answer 18

greenhouse gas released by cars and burning

Question 19

mitigation

Answer 19

trying to REDUCE the severity of the situation

Question 20

adaption

Answer 20

CHANGING to fit the new circumstances better

Question 21

carbon capture

Answer 21

capturing the carbon released in industries and cars and storing it in permeable rocks such as sandstone or underground to stop it from rising to the atmosphere and blanketing the earth

Question 22

afforestation

Answer 22

planting more trees to help combat the amount of co2 in the atmosphere as trees can remove it through photosynthesis

Question 23

kyoto protocol

Answer 23

enforced in 2005 by 192 countries to try to reduce the greenhouse gas emissions
