2.1 natural processes affecting climate chg

Question 1

Natural processes affecting climate change

Answer 1

1) earths orbit
-travelling from circular to elliptical shape
2) earth tilt
3) sunspot occurrences
4) large-scaled volcanic eruptions

Question 2

What is Sunspot occurrences.
What happens around it
How does it affect earth temp

Answer 2

• Places of lower temp;
• Places are sunspots radiate more solar radiation to earth
• HIGHER EARTH TEMPERATURE

Question 3

Large scaled volcanoes
What happens to earth temp

Answer 3

-release ashes (CO2, H2O, DUST)
-ashes spread ard lower atm area
-ashes reflect and absorb solar radiation
- prevent S.R. from hitting surface
- lower earth temperature

Question 4

Earths tilt (what’s the specific angle?)
What happens to earth temp
Effect on weather? Summer, winter, ice sheet

Answer 4

-varies from 21.4 ° to 24.5 °
- tilt decrease
- hemisphere leans AWAY from sun
- LESS SOLAR RADIATION TO EARTH
-lower earth temperature
- enable formation of large ice sheets
- warmer winter cooler summer

Question 5

Earths orbit (how frequent?)
What happens to earth temp

Answer 5

• every 100,000 years
  -travels from circular to elliptical (more oval shape)
• most elliptical= MORE SOLAR RADIATION
• higher earth temp
