1
Q

What are the factors controlling temperature and climate change?

A

plastic asthenosphere, the sun, liquid water, and biotic evolution

2
Q

ocean basins opening and closing due continental masses colliding amd roftomg apart; multidirectional process

A

supercontinent cycle (wilson cycle)

3
Q

the interlinkage of the physical and biological

A

the earth system

4
Q

how to describe changes

A

rate, type, frequency , agency

5
Q

non reversible changes

A

creation of earth

6
Q

`unidirectional changes

A

formation of the moon, evolution of atmosphere and oceans, evolution of life

7
Q

chemical fluxes between living and non living invovle storage and transfer between reservoirs

A

biogeochemical cycles

8
Q

types of biogeochemical cycles

A

hyrdologic cycle, carbon cycle

9
Q

water moves between biological and physical reservoirs

A

hydrologic cycle

10
Q

Plants and humans inverse relationship that cycles through breathing process and absorption techniques

A

the carbon cycle

11
Q

how is carbon stored?

A

through forests, limestones, and fossil fuels

12
Q

how is carbon returned to the atmosphere?

A

Buring fossil fuels, cutting down trees, humane breathing

13
Q

methods to study climate?

A

Paleoclimates and computer simulations

14
Q

investigation of past climate variation interpreted by datable earth materials that are climate sensitive

A

paleoclimates

15
Q

aspects of paleoclimates

A

stratigraphic record, fossil record, oxygen isotopes, growth rings on trees

16
Q

where is global warming occuring and why?

A

places where volcanic gases can trap heat, rifting and expanding mid ocean ridges, increased volcanic activity, burning fossil fuels, and population growth

17
Q

sudden addition or remval of greenhouse gases can alter the climate

A

greenhouse effect

18
Q

List the types of short term climate changes

A

large volcanic eruptions, variable ocean currents, variable green house gas concentration

19
Q

largest catestrophic event in history

A

KT Cretaceous-Tertiary Boundary Event

20
Q

How does plate tectonic tie in with Climate?

A

Change in position of the continents, volcanic gases trapping heat, Mountain building leads to increased weathering

21
Q

List Anthropogenic Changes

A

Increased population, deforestation (carbon based), Pollution, acidification, radioactive, global warming

22
Q

Why is population increase not necessarily good?

A

Humans used more resources than they need which burns more carbon and makes the world warmer, promoting global warming

23
Q

Name ways that humans pollute the environment?

A

smog, fuel and oil, acid rain

24
Q

How is global warming increasing?

A

Human green house gases, industrial revolution used carbon, more cars

25
Q

3 evident of global warming

A

glacial retreat, more intense hurricanes, rising sea levels
