Question

The oceans affect the biosphere by _____. i) producing a substantial amount of the biosphere's oxygen ii) adding carbon dioxide to the atmosphere iii) being the source of most of earth's rainfall iv) regulating the ph of freshwater biomes and terrestrial groundwater

Answer 1

iii) being the source of most of earth's rainfall

Step-by-step explanation:

The oceans are most responsible for the formation of rain that occurs on our planet. This is because the water of the oceans in contact with the solar heat, evaporates, and becomes water vapor. This vapor is captured by clouds that become overloaded and start the precipitation process.

Precipitation is essential for human activities, such as agriculture, in addition to contributing to the smooth functioning of the hydrological cycle.

Answer 2

The oceans affect the biosphere by adding carbon dioxide to the atmosphere, producing a substantial amount of the biosphere's oxygen, moderating the climate of the terrestrial biomes and also being the source of most of Earth's rainfall.
Biosphere is the layer of the planet earth where life exists. This layer ranges from heights of up to ten kilometers above sea level, used by some birds in flight, to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometers deep.
