Earth & Space Science - Unit 1 HS-ESS1-1 - Fusion in the Sun

Front

What is the primary element that the Sun fuses to produce energy?

Back

Hydrogen.

Front

What is nuclear fusion?

Back

The process of combining the nuclei of small atoms to form more massive nuclei, releasing energy.

Front

What is the main product of nuclear fusion in the Sun?

Back

Helium.

Front

How does the Sun's energy reach Earth?

Back

In the form of electromagnetic radiation.

Front

What is the role of electrons in an atom?

Back

Electrons are negatively charged particles that do not contribute to the mass of the atom.

Front

What is the difference between nuclear fusion and nuclear fission?

Back

Nuclear fusion combines small nuclei to form a larger nucleus, while nuclear fission splits a large nucleus into smaller nuclei.

Front

What is the significance of the Sun's mass in estimating its lifespan?

Back

The amount of hydrogen it started with, based on its mass, helps estimate how long it can continue to fuse hydrogen into helium.

Front

What type of radiation is produced during fusion in the Sun's core?

Back

Electromagnetic radiation.

Front

What is fission?

Back

The splitting of a nucleus into smaller nuclei, releasing energy.

Front

What is the core of the Sun?

Back

The innermost layer where nuclear fusion occurs, producing energy.
