Questions and Answers

Which of the following best describes the concept of climate?

  • The daily temperature and precipitation in a specific location.
  • The atmospheric conditions at a specific time and place.
  • A short-term change in weather patterns.
  • The average weather conditions of a region over a long period. (correct)

Albedo is a measure of which of the following?

  • The amount of heat radiated from the Earth's surface.
  • The angle of the sun's rays hitting the Earth.
  • The amount of solar radiation absorbed by a surface.
  • The reflectivity of a surface. (correct)

How does a higher albedo affect the climate system?

  • It causes the Earth to absorb more solar radiation, leading to warming.
  • It has no significant impact on the Earth's temperature.
  • It causes the Earth to reflect more solar radiation, leading to cooling. (correct)
  • It primarily affects wind patterns but not temperature.

Flashcards

What is Climate?

The average weather conditions in a specific location over a long period, including temperature, precipitation, and wind.

What is Albedo?

The measure of how much light that hits a surface is reflected without being absorbed.

How Albedo Affects Climate

Albedo affects climate by influencing how much solar radiation is absorbed by the Earth. High albedo surfaces reflect more energy, leading to cooling. Low albedo surfaces absorb more energy, leading to warming.

Ocean Currents and Energy Distribution

Ocean currents distribute energy by transporting warm water from the equator towards the poles, and cold water from the poles towards the equator, thus regulating global temperatures.
