What is the importance of global winds moving warm air away from the equator?

They spread warmth into more areas, which increases global biodiversity.

oxygen
400
the layer of electrically charged particles
ionosphere
400
this is made up of 3 atoms of oxygen

Elizabeth is traveling from the foothills to the mountains. When she gets closer to the mountains, her ears feel blocked and she cannot hear well. Explain why this occurred.

Air pressure decreases as altitude increases

How does the sun contribute to weather patterns?

The sun provides energy to evaporate water into the atmosphere.
