The Kuiper Belt is primarily composed of small icy bodies, including dwarf planets, comets, and other objects made mostly of ice and rock.

Front

What type of tide occurs during a full moon or new moon?

Back

Spring tide occurs during a full moon or new moon when the gravitational forces of the moon and sun align, resulting in higher high tides and lower low tides.

Front

What gives Mars its reddish appearance?

Back

Mars appears red due to iron oxide (rust) on its surface.

Front

Define geocentric model.

Back

The geocentric model is an astronomical theory that places the Earth at the center of the universe, with all other celestial bodies revolving around it.
