What are the 5 causes of weather!
What causes weather?
Every weather pattern has a knock-on effect, creating a ripple effect around the world. That’s why weather can sometimes seem chaotic.
It’s constantly changing.
describes how hot or cold the atmosphere is.
Weather patterns examples
The atmosphere absorbs heat energy from the sun. But human activities, such as releasing greenhouse gases into the atmosphere, can also affect the earth’s temperature.
is a result of the weight and density of the air.
Atmospheric pressure changes as air becomes warmer or colder, because the temperature of air affects how dense it is.
Warm air molecules have more energy and move further apart, meaning that warm air is less dense than cold air.
Atmospheric pressure also decreases as you move higher into the atmosphere. Imagine the atmosphere as a huge ocean of air that we live underneath.
The pressure underneath the weight of the entire ocean is far greater than the pressure near the ocean’s surface. That’s why atmospheric pressure decreases as you move higher in the atmosphere.
