Can you match the vocabulary word to the correct definition?
- a meteoroid that reaches Earth’s surface without burning up completely
- when the comet gets close enough to the sun, solar radiation heats the ice so that the comet gives off gas and dust to form a tail
- the region of the solar system that is between the orbits of Mars and Jupiter and in which most asteroids orbit
- circles that are somewhat stretched out in shape
- a bright streak of light that results when a meteoroid burns up in the Earth’s atmosphere
- electrically charged particles
- a small, rocky object that orbits the sun, usually in a band between the orbits of Mars and Jupiter
- A small body of ice, rock, and cosmic dust that follows an elliptical orbit around the sun and gives off gas and dust in the form of a tail as it passes close to the sun
- A relatively small rocky body that travels through space
- A comet is a relatively small solar system body that orbits the Sun. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail.
- Asteroids are small solar system bodies that orbit the Sun. Made of rock and metal, they can also contain organic compounds. Asteroids are similar to comets but do not have a visible coma (fuzzy outline and tail) like comets do.
- A meteoroid is a small rock or particle of debris in our solar system. They range in size from dust to around 10 metres in diameter (larger objects are usually referred to as asteroids).
A meteoroid that burns up as it passes through the Earth’s atmosphere is known as a meteor. If you’ve ever looked up at the sky at night and seen a streak of light or ‘shooting star’ what you are actually seeing is a meteor.
- A meteoroid that survives falling through the Earth’s atmosphere and colliding with the Earth’s surface is known as a meteorite.
