6SCI - U1 L4-6 Terrestrial, Gas Giant Planets, and Small Bodies

Across
A meteoroid that reaches earth's surface withOUT burning up.
Small bodies mostly located between the orbits of Mars and Jupiter, and are irregularly shaped, rocky objects with different mineral compositions.
The four small, dense, rocky planets that orbit closest to the sun. They have similar compositions and consist of an outer crust, a central core, and a mantle.
The second largest planet with a large ring system at its equator made up of small, icy, orbiting particles.
Winds circle this planet causing extreme storms as clouds stretch and appear as red and white spots. The most popular of these is the Great Red Spot. This planet also has the most moons at 60.
A small body of ice, rock, and dust that follows a highly elliptical orbit around the sun. As it passes the sun it gives off gas and dust in the form of a coma or a tail.
A meteoroid that gains friction, heats up, causing a glow. This bright streak of light is the result of a meteoroid burning up in Earth's atmosphere.
Down
A region of the solar system just beyond the orbit of Neptune, containing small bodies made mostly of ice - methane ice, ammonia ice, and water ice.
A rocky body that is sand-grain to boulder size and travels through space.
Group of planets that orbit farthest from the sun. They are large and have deep, massive gas atmospheres, and are made up mostly of hydrogen and helium.
This planet is known as "Earth's twin", but rotates clockwise, or in a retrograde rotation. This planet is also made up of craters and volcanoes with a toxic atmosphere.
A spherical region that surrounds the solar system and extends almost halfway to the nearest star, where long-period comets originate,
This planet's atmosphere contains methane that absorbs light and gives off a blue-green color. Also, it tilts at a 98 degree angle as it orbits the sun, while 27 moons orbit it's equator,
Planet with the most extreme temperatures. It is also the smallest planet and mostly made up of a central core.
Known as the Blue Ice Giant, this planet is very similar to Uranus, but farthest from the sun. It has the strongest winds and is said to have a warm interior that controls the weather.
Made up of vast liquid-water oceans and moderate temperatures that provide ideal conditions for life. The only planet whose surface is divided into tectonic plates.
Planet composed largely of dark volcanic rock and boulders. It has a very thin atmosphere, mostly composed of carbon dioxide in which temperatures at the poles get cold enough to freeze a layer of it.
