b. radioactive substances
c. gravitational contraction
d. past bombardment by asteroids

Answers

Answer 1
Answer: it is b 
radioactive substances don't heat the earth
Answer 2
Answer:

Final answer:

Past bombardment by asteroids is not a source of Earth's internal heat. The correct sources are mantle convection, radioactive substances, and gravitational contraction. Asteroid impacts are not a constant or ongoing source of internal heat.

Explanation:

The Earth's internal heat is primarily caused by three sources: mantle convection, radioactive substances, and gravitational contraction. However, past bombardment by asteroids is not a source of Earth's internal heat.

Let's briefly define these terms:

  • Mantle Convection: This is a process by which heat from Earth's interior is transferred towards the surface.
  • Radioactive Substances: These are naturally occurring elements within Earth that release heat as they decay.
  • Gravitational Contraction: This is the process wherein the Earth releases heat as it contracts under its own gravity. This occurred more in the planet's early history, but still contributes today.
  • Past Bombardment by Asteroids: While significant asteroid impacts likely caused localized heating and had a major influence on Earth's early history, they are not a sustained, ongoing source of Earth's internal heat.

Which of the following does not release carbon back into the atmosphere? a.volcanic eruption b.respiration c. burning fossil fuels d. photosynthesis

Answers

Photosynthesis does not release carbon back into the atmosphere. Option (d) is correct.

What do you mean by Atmosphere?

A layer of gases known as the atmosphere envelops the planet Earth. The gravitational pull of the planet's neighbor, Earth, keeps it close to the surface. The three primary elements of the atmosphere are nitrogen, oxygen, and argon.

Naturally, photosynthesis removes carbon dioxide, and trees are particularly adept at storing the carbon that is taken out of the atmosphere via photosynthesis.

The fermentation of lactic acid does not result in the production of carbon dioxide gas. The method doesn't use any oxygen, which is the cause of that. However, carbon dioxide gas is a byproduct of other activities such aerobic respiration and alcoholic fermentation.

Therefore, Option (d) is correct. Photosynthesis is correct answer.
