What is the Oort Cloud?

  1. A cloud of comets at the outer edge of the solar system

  2. A region of intense heat and pressure at the center of the solar system

  3. A group of planets orbiting a distant star

  4. A cloud of gas and dust from which the solar system formed

Show answer
Correct Option: A
Explanation:

The Oort Cloud is a cloud of comets located at the outer edge of the solar system.

What is the future of the solar system?

  1. The Sun will eventually become a red giant and engulf the inner planets

  2. The Sun will eventually become a white dwarf and cool down

  3. The Sun will eventually become a black hole and collapse in on itself

  4. The Sun will eventually explode as a supernova

Show answer
Correct Option: A
Explanation:

The future of the solar system is that the Sun will eventually become a red giant and engulf the inner planets, including Earth.
