Read each question carefully and provide your answers in the spaces provided. For multiple-choice questions, circle the letter corresponding to the correct answer. For true/false, circle T or F.
1. Which of the following best describes Earth's energy budget?
The total amount of energy stored within Earth's core.
The balance between incoming solar radiation and outgoing terrestrial radiation.
The amount of energy required to melt Earth's ice caps.
The conversion of solar energy into chemical energy by plants.
2. What is the primary source of energy for Earth's climate system?
Geothermal energy from Earth's interior.
Tidal energy from lunar gravitational pull.
Solar radiation from the Sun.
Energy from fossil fuel combustion.
1. The albedo effect describes the absorption of solar radiation by Earth's surface.
True
False
2. Greenhouse gases trap outgoing longwave radiation, leading to a warming effect.
True
False
1. Approximately 30% of incoming solar radiation is back to space by clouds, aerosols, and Earth's surface.
2. The Earth's surface primarily emits energy in the form of radiation.
3. An increase in atmospheric concentrations of greenhouse gases can lead to an enhanced effect, causing global warming.
1. Explain the concept of planetary albedo and provide two examples of surfaces with high albedo.
2. Describe the role of the atmosphere in regulating Earth's temperature through the greenhouse effect.
Refer to the diagram below to answer the following questions.
1. Based on the diagram, how does Earth's tilt influence the distribution of solar radiation across its surface, leading to seasons?
