Study Notes

Moons

  • Moons are natural satellites that orbit a planet.
  • Many planets have moons, and some planets have many moons.
  • Saturn has more than fifty moons.
  • The Earth has just one moon - the Moon.

Origin of the Moon

  • Scientists believe that it was formed when a Mars-sized planet collided with the early Earth, throwing some of the crust into orbit.

Dark side of the Moon

  • The Moon has no side that is constantly dark; the front and back are alternately lit as the Moon rotates.
  • Far side is a more accurate term.

How the Moon Shines

  • The Moon is not luminous. It doesn't emit its own light.
  • Instead, it reflects light from the Sun back to Earth.
  • This is what we might call moonlight.

Phases of the Moon

  • (Diagram of phases)

07 Day and Night and time zones

  • The Earth is divided into degrees of longitude and latitude.
  • Lines of Longitude are called meridian lines.
  • The Prime Meridian passes through Greenwich at 0°.
  • A longitude is an angle from the prime meridian, measured to the east (+) and west (-).

The Earth is divided into 24 time zones

  • As the Earth rotates on its axis, different parts of its surface enter and exit daylight at different times.
  • Every 15 longitudinal degrees away from the Prime Meridian, the time changes by an hour.
  • This has created 24 time zones around the world.

The Seasons

  • The Earth is tilted on its axis 23.5 degrees.

  • It is divided into two halves at the equator - the northern hemisphere and the southern hemisphere.

  • (Diagram of Earth's tilt and seasons)

  • In the summer, temperatures are warmer because the days are longer and the Sun's rays are spread out over a small area as the hemisphere is tilted towards the Sun.

  • In the winter, the temperatures are colder. This is because the days are shorter and the Sun's rays are spread out over a large area as the hemisphere is tilted away from the Sun.

  • Spring and autumn result from both hemispheres receiving equal amounts of sunlight.

Climate Change

Global Warming

  • Carbon dioxide is a greenhouse gas.
  • Extra carbon dioxide in the atmosphere increases the greenhouse effect.
  • More energy is trapped by the atmosphere.
  • This causes an increase in the temperature of the earth.
  • This is known as Global Warming
  • The enhanced Greenhouse Effect is resulting in Climate Change.

Effects of Climate Change include:

  • Glaciers melting
  • Sea levels rising
  • Changes in rainfall, leading to flooding or droughts
