EES 1.1 Vocab - Understanding Planets and Celestial Bodies

What is the definition of a gas giant?

• A small rocky planet with a thin atmosphere

• A large planet that is not primarily composed of solid matter, typically having a thick atmosphere of hydrogen and helium

• A planet made entirely of ice

• A planet that orbits outside the solar system

What is the definition of a terrestrial planet?

• A planet made mostly of gases

• A planet with a solid surface, primarily composed of rock and metal

• A planet with a glowing tail

• A planet that does not orbit the sun

What is the definition of a Jovian planet?

• A small, rocky planet

• A type of planet that is large, has a thick atmosphere, and is primarily composed of gases

• A planet that orbits another planet

• A planet with a solid metal core only

What is the definition of a dwarf planet?

• A planet that is larger than Jupiter

• A celestial body that orbits the sun and is similar to a planet but does not clear its orbital path of other debris

• A planet that has rings

• A planet that is made only of gas

What is the definition of the nebular hypothesis?

• The theory that the solar system formed from a rotating cloud of gas and dust

• The idea that planets formed from comets

• The belief that the Earth is the center of the universe

• The process of burning fuel in space

What is the definition of the solar nebular theory?

• The theory that explains the formation of the solar system from the solar nebula, which collapsed under its own gravity

• The theory that explains the movement of asteroids

• The theory that explains the phases of the moon

• The theory that explains the composition of comets

What is the definition of a meteoroid?

• A large planet in the outer solar system

• A small rocky or metallic body in outer space, smaller than an asteroid

• A moon of Jupiter

What is the definition of a comet?

• A planet with a thick atmosphere

• A celestial body composed of ice, dust, and rocky material that, when close to the sun, develops a glowing coma and tail

• A small rocky body in the asteroid belt

• A star with a tail
