physical caudes climate change

Question 1

sunspots

Answer 1

the more sunspots there are the higher the temperatures

Question 2

solar variation

Answer 2

the amount of solar energy released by the sun is fairly stable, but increases and decreases at certain times.

overtime solar activity can increase or decrease global temperatures.

Question 3

volcanic eruptions

Answer 3

When a volcano erupts, it
releases a large amount of
ash and gases into the
atmosphere.

This shields the Earth from
incoming energy, lowering
temperatures.

For example, Mount Pinatubo
erupted in 1991 -global
sunlight fell by 10% meaning
temperatures decreased by
0.5% globally

Question 4

milankovich cycles

Answer 4

Milankovitch cycles are changes in
the Earth’s orbit and tilt that alter
the amount of energy Earth
receives.
More energy means higher
temperatures.

A greater tilt towards the sun means warmer summers
and colder winters, a lower tilt has the opposite effect.

Question 5

ocean currents

Answer 5

Some ocean currents transfer warm water to cooler
areas, others transfer cool water to warmer areas.
Changes in ocean currents can impact global temperature.
such as the periodic warming (El Niño) and cooling (La
Niña) of the Pacific Ocean.

Question 6

ocean currents, warming of temperatures

Answer 6

Uk winters are 5⁰C warmer due to atlantic drift
