Climates and Biomes

What factors are primarily used to classify Earth's land surface into biomes?

• Ocean currents, wind patterns, and soil type.

• Climate, vegetation, and the organisms living in an area.

• Mountain ranges, river systems, and human population density.

• Geological formations, seismic activity, and atmospheric pressure.

Which of the following best describes the climate and vegetation of tropical rainforests?

• Dry, extremely hot, with very little vegetation.

• Hot all year round, with less dense vegetation and lower animal diversity.

• Warm and humid, with high precipitation all year round and dense vegetation.

• Mild winters and cool summers, dominated by trees that lose their leaves in fall.

Compared to tropical rainforests, tropical grasslands are characterized by:

• Cooler temperatures and higher precipitation.

• Hot temperatures all year round, with less precipitation and less dense vegetation.

• Mild winters and cool summers, with deciduous trees.

• Extremely dry conditions and specialized plant adaptations.

What unique characteristic allows plants and animals to survive in desert biomes?

• Abundant water sources.

• Mild and consistent temperatures.

• Highly specialized adaptations for harsh conditions and extreme temperatures.
