Q

Example of alpine glaciers

A

Mer de Glace, France

17
Q

Accumulation

cryospheric

A

During the winter months in mountainous regions glaciers will in size. When it snows, the snow accumulates on the glaciers and forms new ice.

18
Q

Ablation

and cause

A

During the summer months, glaciers will melt (ablation) causing the cryosphere to decrease in size

19
Q

Steady-state equilibrium

in terms of ice

A

Balance between accumulation and ablation over time.

20
Q

Anthropogenic

A

Caused by humans

21
Q

Seasonal changes

A

Accumulation
Ablation
Steady-state equilibrium

22
Q

Long term changes

2

A

plate movements

milankovitch cycles

23
Q

Milankovitch cycles

A

Orbital cycles

24
Q

How many milankovitch cycles

A

3

25
Q

Plate movement

A

tectonic

26
Q

Epoch

A

time period

27
Q

Paleocene and Eocene

A

geological epochs

28
Q

Monsoon

A

Rapid transfer of rainfall causing the wet season in India, Sri Lanka, Pakistan and part of Bangladesh

29
Q

When is the monsoon

A

May, June, July

30
Q

Condensed overview of monsoon cause

A

land hotter than sea
water evaporates
condenses over mountains

31
Q

How much rainfall in Monsoon

A

2/3rds of a years rainfall

32
Q

El nino

A

A climate cycle that occurs every 5-7 years between South America, Australia and South-east Asia

33
Q

La nina

A

Stronger winds than a normal year

34
Q

Temporal change

A

seasonal, temporary change

35
Q

Arid

A

conditions means a severe lack of water, usually defined as annual rainfall totalling less than 200-250mm.

36
Q

Example of place with increasing aridity

A

Sahel region
