</span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;">1. a) Phases of the Moon are caused by the different <span class="Apple-style-span" style="background-color: purple;">positions</span> of the <span class="Apple-style-span" style="background-color: purple;">Sun</span> and the <span class="Apple-style-span" style="background-color: purple;">Earth</span> to the </span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;"><span class="Apple-style-span" style="background-color: purple;">Moon</span>.</span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;"> b) These changes occur when the Moon revolves round the Earth. At the same time, the Earth and Moon revolve round the Sun.</span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;">2. As the Moon is illuminated by the Sun, half of the Moon is bright while the other half is dark.</span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;">3. From Earth, the Moon can be seen at different angels on different nights.</span><br />

Therefore, <span class="Apple-style-span" style="background-color: purple;">different shapes</span> of the Moon are seen on different nights.</span><br />
<span class="Apple-style-span" style="color: cyan; font-family: Arial, Helvetica, sans-serif;">5. The shape of the Moon depends on how much of the illuminated part of the Moon faces the Earth.</span><br />

<br />
<span class="Apple-style-span" style="color: #f4cccc;">1. The rotation of the Earth on its axis takes place at all times. However, the position of the Sun is always fixed.</span><br />
<span class="Apple-style-span" style="color: #f4cccc;">2. At any one time,</span><br />
<span class="Apple-style-span" style="color: #f4cccc;"> a) half of the Earth is facing the Sun. This part of the Earth receives sunlight and experiences day.</span><br />
<span class="Apple-style-span" style="color: #f4cccc;"> b) half of the Earth is facing away from the Sun. This part of the Earth does not receive sunlight and, therefore, is in darkness. </span><br />
<span class="Apple-style-span" style="color: #f4cccc;">3. The Earth takes 24 hours to complete one rotation. during every 24 hours :</span><br />
<span class="Apple-style-span" style="color: #f4cccc;"> a) half of the Earth experiences day</span><br />
<span class="Apple-style-span" style="color: #f4cccc;"> b) half of the Earth experiences night.</span><br />

Like the Earth, the Moon also rotates on its axis from <b>west</b> to <b>east.</b><br />
2. While rotating on its axis, it also revolves round the Earth.<br />
3. The time taken for the Moon to make one rotation is the same as the time taken for it to go round the Earth. Therefore, from the Earth, we always see the same side of the Moon.<br />
4. The Moon takes 27 1/3 days to make one complete rotation on its axis.<br />
5. The Moon takes the same time (27 1/3days) to make one complete revolution around the Earth.<br />

<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: large;">1. The Earth spins on its axis like a spinning top. This spinning motion is called <b>rotation</b>.</span><br />
<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: large;">2. An <b>axis </b>is an imaginary line that goes through the centre of the Earth. It links the north pole to the south pole.</span><br />
<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: large;">3. The earth rotates from <b>west</b> to <b>east</b>.</span><br />
<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: large;">4. a) The Earth takes <b>24 hours</b> to make one complete rotation.</span><br />
<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: large;"> b) It takes one year to make one complete movement round the Sun. This movement is called a <b>revolution.</b></span><br />
