The Carbon cycle is a geological process that regulates the CO2 - level in the atmosphere and with that, the
temperature of the planet's
surface: In the
ocean, CO2, in its dissolved form, undergoes a chemical reaction and is then transported into Earth's mantle.
Here's some reasons why: Venus's
surface temperature hovers around a sweltering 870 degrees Fahrenheit (465 degrees Celsius), its
surface pressure is about 90 times that
of Earth (which is akin to the pressure a kilometer, or 0.6 mile, below the
ocean's
surface), and there are no seasons there.
The rising
temperatures cause layers
of ocean water to stratify so the more oxygen - rich
surface waters are less able to mix with oxygen - poor waters from the deeper
ocean.
Ocean currents affect the
surface temperature of the
oceans and thus the heat exchange with the atmosphere — eventually causing climate variations on the adjacent continents.
The die - off is due to a combination
of rising sea
surface temperatures and decreased

Sea -
surface temperature is an important driver
of the weather, and because the

But a reduction in the number and intensity
of large hurricanes driving
