Solar System Objects: Lesson 1 Topic 4: Lehrke (HW)

Front

What force is essential for the creation of the solar system?

Back

Gravity is essential for the creation of the solar system.

Front

How many kilometers is one astronomical unit (AU)?

Back

One astronomical unit is equal to 150,000,000 kilometers.

Front

What is the core of the sun?

Back

The core is the central region of the sun where hydrogen atoms fuse together, creating energy through nuclear fusion.

Front

What two factors are responsible for the intense heat and pressure in the sun's core?

Back

Fusion and gravity are responsible for the intense heat and pressure in the sun's core.

Front

What are solar prominences?

Back

Solar prominences are huge loops of plasma on the surface of the sun that are polarized and often link together.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where hydrogen atoms combine to form helium, releasing energy in the process.

Front

What is the role of gravity in the solar system?

Back

Gravity holds the solar system together, keeping planets in orbit around the sun.

Front

What is the difference between the convection zone and the core of the sun?

Back

The convection zone is the outer layer of the sun where energy is transferred by convection, while the core is where nuclear fusion occurs.

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the sun's photosphere that appear as spots darker than the surrounding areas.

Front

What is the radiative zone of the sun?

Back

The radiative zone is the layer of the sun where energy is transferred outward by radiation.
