Describe how the gravitational pull of Earth influences the way matter behaves on Earth's surface.
Then, explain how this gravitational pull changes Earth's surface during earthquakes, land-
slides or mudslides, and floods.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
