Questions and Answers

How does latitude primarily affect the climate of a region?

  • By influencing the amount of solar radiation received. (correct)

  • 1000 meters
  • 4000 meters

Which of these is the most accurate comparison between weather and climate?

  • Weather includes only temperature and precipitation, while climate includes all atmospheric variables.
  • Weather refers to short-term atmospheric conditions; climate is the long-term pattern of weather. (correct)

  • Weather is the long-term average of atmospheric conditions, while climate is the daily condition.

How do large bodies of water affect the temperature of coastal regions during the summer?

<p>Coastal regions maintain cooler temperatures because water heats up more slowly than land. (B)</p> Signup and view all the answers

What impact do greenhouse gases have on the Earth's temperature, and why are they less effective at higher altitudes?

<p>They help maintain a warm temperature on Earth; greenhouse gas concentration decreases with increasing altitude making them less effective. (C)</p> Signup and view all the answers

How does the temperature of air above land typically compare to the temperature of air above the sea during the daytime, and what effect does this have?

<p>Air above land is warmer, causing air to move from land to sea. (A)</p> Signup and view all the answers

Why do places near bodies of water generally have more moderate temperatures compared to inland areas?

<p>Water heats up and cools down more slowly than soil, moderating air temperatures. (B)</p> Signup and view all the answers

Study Notes

Climate vs. Weather

  • Weather is the condition of the atmosphere at a specific place and time. It can change in a few minutes or hours.
  • Climate is the general pattern of weather in a certain area over a long period of time. It takes a very long time to change (typically 30 years or more).
  • The difference between weather and climate is a matter of time.

Factors Affecting Climate

1. Latitude

  • Latitude is the measurement of distance north and south of the equator.
  • Imaginary lines that form circles around the Earth, parallel to the equator.
  • Latitude influences climate because different latitudes receive different amounts of solar radiation.

2. Altitude

  • Altitude refers to the elevation of a place above sea level.
  • Air temperature generally decreases as altitude increases.
  • For every 1000 meters of altitude gain, there is a drop of 6.5 degrees Celsius.
  • Higher elevation translates to thinner air.

3. Bodies of Water

  • Large bodies of water (oceans, seas, and lakes) moderate climate.
  • Water heats and cools more slowly than land.
  • Coastal regions tend to be cooler in the summer and warmer in the winter compared to inland areas.
  • Land absorbs and releases heat faster than water.

4. Topography

  • Topography is the study of the forms and features of land surfaces.
  • Landforms (e.g., mountains) can impact the amount of precipitation in a region.
  • The windward side of a mountain range receives more precipitation due to upward-moving air that condenses and forms clouds.
  • The leeward side of a mountain range experiences less precipitation because the air moving down the mountain warms and dries.

5. Ocean Currents

  • Ocean currents play a crucial role in regulating global temperatures.
  • Ocean currents transport heat around the planet, affecting regional climates.
  • Warm ocean currents can moderate climates by bringing warmer temperatures to coastal areas, while cold currents can cause cooler climates.
  • The Coriolis effect influences the direction of ocean currents—to the right in the northern hemisphere and to the left in the southern hemisphere.
  • The amount of solar radiation absorbed by the ocean is significant, acting like a heat-retaining solar panel, especially in tropical waters.
