Questions and Answers

How does proximity to the sea most significantly influence regional climates?

  • It decreases rainfall due to the absorption of moisture by the ocean.
  • It regulates temperatures, leading to milder winters and cooler summers. (correct)
  • It leads to increased occurrences of monsoons, altering wind patterns.
  • It results in more extreme temperature ranges due to increased humidity.

Which characteristic is least likely to contribute to the formation of a desert climate?

  • High atmospheric pressure causing descending air masses.
  • Close proximity to a large body of water. (correct)
  • Latitude within the subtropical high-pressure belt.
  • Location in the rain shadow of a mountain range.

What best describes the effect of elevation on climate?

  • Temperature rises and precipitation increases.
  • Temperature decreases and precipitation decreases.
  • Temperature decreases and precipitation increases. (correct)
  • Temperature rises and precipitation decreases.

Equatorial Climate

The sun's rays hit regions along the Equator more directly, leading to hot temperatures all year round and regular, abundant rainfall due to low pressure and humid trade winds.

Tropical Climates

These climates have bigger temperature ranges and distinct wet and dry seasons, differentiating them from the consistent conditions of equatorial climates.

Hot Desert Climate

Characterized by hot or warm average temperatures, very little rainfall (less than 200 mm), and large temperature ranges, even between day and night.

Mediterranean Climate

High temperatures in summer (more than 20ºC) due to warm, dry air masses. Mild winters (more than 6ºC) because of the sea. Moderate (300 - 800mm), irregular rainfall.

Study Notes

  • Earth's orbit and tilted axis cause seasons and climate zones.
  • Latitude, proximity to the sea, and elevation influence weather and climate, creating different climate types within the main climate zones.

Impact Factors

  • Latitude: Affects the angle at which the sun's rays hit the Earth, influencing temperature.
  • Proximity to Sea: Regulates temperature and affects the amount and regularity of rainfall.
  • Elevation: Temperature decreases with elevation; precipitation increases, often as snow.

Hot Zone Climates

  • Equatorial, tropical, and desert climates.

Equatorial Climate

  • Found along the Equator
  • Hot temperatures year-round with hardly any annual temperature range.
  • Regular and abundant rainfall due to low pressure and humid trade winds.

Tropical Climates

  • Larger temperature ranges and distinct wet and dry seasons, differentiating from equatorial climate.
  • Includes humid and dry variations.

Hot Desert Climate

  • Very little rainfall (below 200 mm).
  • Large temperature ranges, even between day and night.

Temperate Zone Climates

  • Mediterranean, oceanic, continental, and steppe climates.

Mediterranean Climate

  • High summer temperatures (above 20ºC) due to warm, dry air masses from subtropical regions.
  • Mild winters (above 6ºC) because of the sea.
  • Moderate (300-800 mm per year) and irregular rainfall.
  • Examples: Mediterranean Basin, coastal regions of California and Chile, southwest Australia, and South Africa.

Oceanic Climate

  • Regulated temperatures and abundant regular rainfall due to proximity to the sea.
  • Found on the western coasts of Europe and North America, some South American coastal regions, New Zealand, and parts of Australia and Africa.

Continental Climate

  • Inland regions experience bigger temperature ranges (hot summers, cold winters).
  • Moderate rainfall.

Steppe Climate

  • Drier regions and less rainfall.
  • Even bigger temperature ranges than continental climates.

Cold Climates

  • Mostly in cold zones within polar circles with less intense sunlight.

High Mountain Climate

  • Temperature decreases with elevation.
  • Precipitation increases, often as snow.
  • Occurs at any latitude if the region is high enough.
  • Example: Cayamba volcano in Ecuador.

Polar Climate

  • Very low temperatures throughout the year.
  • Summer temperatures rarely exceed 5ºC; winter can fall below -40ºC.
  • Scarce precipitation, always as snow.
  • Occurs inside the Arctic and Antarctic Circles.
