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
