Which best explains mantel convection
Snowcat [4.5K]

Answer:

The heat given off by Earth's core is circulated through mantle convection.

Explanation:

Heating materials usually causes them to <em>expand</em>; as they become hotter, they also become less dense. Convection describes the transfer of heat from hot areas of liquids and gases to cooler ones. This causes the heated, less dense material to rise and more dense material to fall, as it’s pulled by gravity. Super-heated metal forming Earth’s central core heats rock in the mantle; the hot and cool rock slowly rise and sink- this circulation process is called mantle convection.

There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.

<h3>Features associated with each of Earth's four spheres.</h3>

<h3>Hydrosphere </h3>

It is the set of all the water on the planet, including those that form clouds.

<h3>Lithosphere</h3>

The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.

<h3>Atmosphere</h3>

It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.

<h3>Biosphere </h3>

It is the part of our planet that can support life

<h3>Internal processes</h3>

The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.

With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.
