You have seen that Earth's terrestrial biomes reflect regional variations in climate. But what determines these climatic variations? Interpret the following diagrams in reference to how each represents effects on global patterns of temperature, rainfall, and winds. a. Solar radiation and latitude: b. Earth's orbit around the sun: c. Global patterns of air circulation and rainfall:

Verified step by step guidance

1. Examine the first diagram (a) which shows solar radiation and latitude. Note how the intensity of solar radiation varies with latitude, being most intense at the equator and decreasing towards the poles.
2. Analyze the second diagram (b) which illustrates Earth's orbit around the sun. Observe the tilt of Earth's axis and how it affects the distribution of sunlight throughout the year, leading to seasonal variations in temperature.
3. Look at the third diagram (c) which depicts global patterns of air circulation and rainfall. Identify the major air circulation cells (Hadley, Ferrel, and Polar cells) and how they influence precipitation patterns, with rising air causing rainfall in the tropics and descending air leading to dry conditions in temperate zones.
4. Integrate the information from all three diagrams to understand how solar radiation, Earth's tilt, and air circulation patterns collectively determine global climate variations.
5. Consider how these climatic factors influence the distribution of terrestrial biomes, with different regions supporting distinct types of vegetation and ecosystems based on their climate.
