Changes of Climate and Seasons：練習問題

Which of the following is a common type of weather?

Which part of the water cycle involves water vapor in the air turning back into tiny liquid water droplets to form clouds?

Earth's speed as it orbits the Sun is not constant; it moves faster when closer to the Sun (perihelion) and slower when farther away (aphelion). Assuming Earth's axial tilt remains at \(23.5^\circ\), how would a significant increase in the variation of Earth's orbital speed (i.e., much faster at perihelion, much slower at aphelion) most likely impact the seasons?

When the weather gets very cold, what do many people wear to keep warm?

During autumn in many parts of the world, deciduous trees change the color of their leaves and then shed them. How does this seasonal change primarily benefit the trees?

The Earth's axis is tilted as it orbits the Sun. How does this tilt cause changes in both the temperature and the length of daylight hours we experience during different seasons in a specific part of the world?

The Earth's axis is tilted as it orbits the Sun. Explain how this tilt, combined with Earth's orbit, causes different seasons in regions far from the equator, and why the Northern and Southern Hemispheres experience opposite seasons.

How does Earth's journey around the Sun lead to different seasons, and how do these seasonal changes affect what animals do?

We experience four different seasons throughout the year: spring, summer, autumn, and winter. Explain two main reasons why Earth has seasons, relating them to how our planet moves in space.

Many people use the words "weather" and "climate" interchangeably, but they have distinct meanings.
a) Explain the difference between weather and climate.
b) Describe one significant human activity that contributes to global climate change and explain how it leads to this change.
