31
Q

Describe the heating and cooling of bodies of water?

A

The oceans heat up and cool down much slower than land, so coastal locations and land have opposing climates

32
Q

What is sea breeze?

A

It is when the ocean is cold while the land is hot during the day

33
Q

What is land breeze?

A

It is when the sea is hot while the land is cold during the night

34
Q

Which countries experience the ENSO Cycle?

A

Countries in the pacific region

35
Q

What is the ENSO Cycle?

A

Naturally occurring phenomenon that involves fluctuating ocean temperatures in the equatorial Pacific, giving us El Niño and La Niña

36
Q

Describe El Niño?

A

Droughts every summer due to increase of temperature in the oceans

37
Q

Describe La Niña?

A

Typhoons due to decrease of temperature in the oceans

38
Q

What is topography?

A

The array of natural and artificial physical features of an area

39
Q

Identify if cooler or warmer air is experienced in the following areas:

  1. Near ocean
  2. Near mountain ranges
  3. Near mountain top
  4. Leeward side of mountain
A
  1. Cooler air
  2. Warmer air
  3. Cooler air
  4. Warmer air
40
Q

Why is it cooler in higher areas?

A

Because atmosphere becomes thin and light, resulting to vapor and rain

41
Q

Describe altitude?

A

Land elevation above sea level

42
Q

What does higher altitude signify?

A

Cooler climate

43
Q

Describe vegetation?

A

Collective term for plants in an area that affect temperature and amount of precipitation experienced

44
Q

What does areas with rich vegetation signify?

A

Fresh air resulting to cooler air

45
Q

Who created the Koppen Climate Classification System?

A

Wladimir Peter Koppen

46
Q

Describe the Koppen Climate Classification System?

A

It uses colors to differentiate the 5 climate zones of the world

47
Q

What are the 5 climate zones and its color code?

A

Zone A: Tropical/Equitorial Zone (blue)

Zone B: Dry/Arid Zone (red, pink, orange)

Zone C: Warm/Mild Zone (green)

Zone D: Snow/Continental Zone (purple and light blue)

Zone E: Polar Zone (grey)

75
Q

What are the 4 natural causes of climate change?

A

Earth’s motion: affects length of season and amount of solar radiation

Tectonic plate movements: earthquakes and volcanic eruptions affects weather and climate

Volcanic eruption: gases affects temperature drop
