When Christopher Columbus set sail on his journey in 1492, he encountered stiff opposition – it is thought many people feared he would fall off the edge of the Earth (which many people thought to be flat). Next In History Index

Next The Bible Many early Christians believed the Earth was flat because of references found in the Bible. For example: “I looked, and there before me stood a tree in the middle of the land. Its height was enormous. The tree grew large and strong and its top touched the sky; it was visible to the ends of the Earth.” Daniel 4:10f However the Bible does not state that the Earth is flat.

 The Sun is the largest object in the solar system.  It is our closest star and is believed to be over 4 billion years old.  There are storms on the surface of the Sun. These storms are known as ‘sunspots’, because they look like spots on the sun. The Sun – Facts Next Index

 The centre (or core) of the Sun is very hot. A process called ‘nuclear fusion’ takes place there. Nuclear fusion produces lots of energy. Some of this energy travels out into space as heat and light. Some of it arrives at Earth.  It is very dangerous to look directly at the Sun. The Sun – Facts Next Index

Shadows Shadows are formed when light from a source is blocked. When the Sun shines on an object it forms a shadow on the ground. Next Index

Shadows change during the day. Next Index

From the position of the shadow you can see the Sun rises in the East and sets in the West. Next Index

The Sun appears to move through the day but, in fact, the Sun does not move. It is the Earth rotating on its axis, which makes it seem that the Sun is moving. As the Sun appears to move and gets higher in the sky, the shadows get shorter. In the morning and evening the Sun is lower in the sky so the shadows are longer. Next Index

Night and Day As the Earth spins on its axis the part that is facing the Sun will be in the light (day). The part of the Earth not facing the Sun will be in darkness (night). Next Index

The Earth – Facts The Earth is one of nine planets in the Solar System. It is over 149 million miles away from the Sun. The Earth spins around a line which goes through it from the North Pole to the South Pole. This is known as the Earth’s axis. Next Index

The axis does not point straight upwards. It is tilted slightly. The Earth – Facts Next Index

The Earth – Facts It takes the Earth 24 hours (one day) to spin round once on its axis. Next Index

It takes the Earth 365 ¼ days (one year) to orbit the Sun. The Earth – Facts Next Index

The Moon – Facts  The Moon orbits the Earth  It takes 28.3 days for one complete orbit (lunar month)  The Moon does not make its own light. You only see the Moon because it reflects light from the Sun. Next Index

The amount of the Moon seen changes from day. These changing views are called the phases of the Moon. Phases of the Moon Next Index
