Unit 6 Solar System and Beyond

What is an eclipse?

• The partial or total blocking of one object in space by another.

• A phenomenon where the sun appears to change color during sunset.

• A type of star that emits light in a specific spectrum.

• A celestial event where two planets align perfectly.

What is the umbra?

• The very darkest part of the moon's shadow during an eclipse.

• The lightest part of the moon's shadow during an eclipse.

• A type of lunar crater.

• The phase of the moon when it is completely full.

What is a star?

• A massive, luminous sphere of plasma held together by gravity, undergoing nuclear fusion.

• A small, cold rock floating in space.

• A giant ball of ice that reflects sunlight.

• A cluster of dust and gas that forms planets.

What is an equinox?

• A time when the sun is at its highest point in the sky.

• The time of year when day and night are approximately equal in length, occurring in spring and autumn.

• A period of the year characterized by the longest days and shortest nights.

• A celestial event marking the start of winter.

What is a meteorite?

• A type of star that falls from the sky.

• A meteor that survives its passage through the atmosphere and lands on Earth.

• A piece of space debris that burns up in the atmosphere.

• A comet that has lost its tail.

What is a planet?

• A large celestial body that orbits a star, is spherical in shape, and has cleared its orbit of other debris.

• A small rocky body that orbits a star and is irregularly shaped.

• A massive gas cloud that forms stars and planets.

• A celestial object that does not orbit any star.

What is a meteor?

• A small particle from space that burns up upon entering Earth's atmosphere, creating a bright streak of light.

• A large rock that orbits the sun and can collide with planets.

• A type of cloud that produces rain and thunderstorms.

• A celestial body that has a solid surface and can support life.

What are tides?

• The rise and fall of sea levels caused by the gravitational forces exerted by the moon and the sun.

• The daily changes in temperature due to the Earth's rotation.

• The movement of ocean currents caused by wind patterns.

• The seasonal changes in weather patterns across the globe.

What is the Milky Way?

• A type of star

• The galaxy that contains our solar system, characterized by its spiral shape.

• A planet in our solar system

• A black hole in the universe

What is the solar system?

• A collection of celestial bodies, including the sun, planets, moons, asteroids, comets, and meteoroids, that are bound by gravity.

• A vast empty space with no celestial bodies.

• A group of stars that are similar in size and brightness.

• A single planet that supports life.
