Force of gravity LaTeX: F=\frac{Gm_1m_2}{r^2}F = G m 1 m 2 r 2
The force of gravity between two objects is dependent on and .

their speeds, their acceleration

the distance between them, their momentum

their masses, their momentums

their masses, the distance between them

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).

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
