What causes the seasons on Earth?
Earth's tilted axis and revolution around the Sun
What is the primary gas that make's up Earth's atmosphere?

menopause
Which statement is correct about Earths seasons?
a) They are caused by changes in Earth's distance from the sun
b) They are opposite in the Northern and Southern hemispheres
c) They are the same in both hemispheres at the same time
d) They only affect temperatures, not daylight hours
B
What percentage of Earth's atmosphere is oxygen?
21%
How do temperature and air density influence air pressure?
warmer air expands and becomes less dense, which leads to lower pressure, while cooler air contracts and is denser, resulting in higher pressure
At what angle is Earth's axis tilted?
23.5 degrees
What layer of the atmosphere doesn't have a lot of the atmospheres mass?
The thermosphere
How does the angle of incoming solar radiation affect Earth's temperature?
More direct angles create higher temperatures
Which gas in Earth's atmosphere is essential for photosynthesis?
Carbon dioxide
What causes wind to form?
because of the sun's unequal heating of the Earth's surface, creating areas of low and high air pressure
