The ecliptic is the mean plane of the apparent path in the sky that the Sun follows over the course of one year; it is the basis of the ecliptic coordinate system. This plane of reference is coplanar with Earth's orbit around the Sun (and 1 Sun's apparent motion; 2 Relationship to the celestial equator; 3 Obliquity of the ecliptic . Relationship Between the Earth, Moon and Sun Rotation A body turning on its axis The Earth rotates once every 24 hours in a counterclockwise direction.

That's what's happening in the Northern Hemisphere here. But when a hemisphere is angled away from the Sun, like the Southern Hemisphere here, the Sun's rays hit it indirectly. OK, so what difference does direct or indirect sunlight make?

How Earth Moves

Oh, there's a huge difference. Let's take a look with a simple experiment.

Environmental Decision Making, Science, and Technology

In this experiment, we're going to use a flashlight to simulate the Sun. Say that the flashlight is a particular sunbeam. If it's shining directly, all its energy is concentrated in a certain area. But if the sunbeam is shining indirectly, the area is larger.

Sun Earth Relationship

This means that the same amount of energy is spread out over a larger area. So in a particular point on the paper it feels colder in the indirect sunbeam than in the direct sunbeam.

And the more indirect the sunbeam, the larger the area. It's important to note that the amount of energy in the sunbeam is always the same. However, if it's spread out over a larger area, we feel it less.

Let's take a look at what this means for the Earth. Here we have a globe that's angled at about It's June, so the Northern Hemisphere is angled towards the Sun. If we shine the flashlight directly on the Northern Hemisphere, we see it illuminates a certain area. But when we move the flashlight to shine indirectly on the Southern Hemisphere, we see that it's illuminating a larger area, just like we talked about.

So let's put it all together. When the Northern Hemisphere is tilted towards the Sun, it's receiving direct sunlight. It feels warmer, which means it's summer there. And the Southern Hemisphere is receiving indirect sunlight, which means it feels cooler. Six months later, when the Earth is on the other side of the Sun, we have the opposite. It's the Southern Hemisphere receiving direct sunlight, so it's summer there. During the equinoxes, all parts of the Earth experiences 12 hours of day and night and that is how equinox gets it name as equinox means equal night.

At winter solstice Decthe North Pole is inclined directly away from the sun. At this point it will be at declination This cycle will carry on, creating the seasons that we experience on earth.

The earth is tilted At the summer solstice which occurs around 21st of June, the North Pole is pointing towards the sun at an angle of Therefore the apparent declination of the sun is positive At the Winter solstice which occurs around 21st December, the North Pole is pointing away from the sun at an angle of Therefore the apparent declination of the sun is negative Change of Seasons Seasons are caused by the Earth axis which is tilted by When the northern axis is pointing to the direction of the Sun, it will be winter in the southern hemisphere and summer in the northern hemisphere.

Relationship Between the Earth, Moon and Sun

Northern hemisphere will experience summer because the Sun"s ray reached that part of the surface directly and more concentrated hence enabling that area to heat up more quickly. The southern hemisphere will receive the same amount of light ray at a more glancing angle, hence spreading out the light ray therefore is less concentrated and colder. Summer solstice Winter solstice Fall equinox Spring equinox Why do we have seasons?

If the tilt of the Earth s axis increased, how would that effect seasons? Indicator I can identify the eight phases of the moon as it revolves around the Earth. Why can we see the moon at night even though it does not produce any light? What is a moon phase? What is a month? How many days is a complete moon cycle? What does a waxing moon phase mean? What does a waning moon phase mean? Label the diagram with the correct moon phase name and shade each phase correctly as seen from earth.

What is a shadow?

What is an eclipse? What is an umbra? What is a penumbra? What moon phase does a lunar eclipse occur in? What moon phase does a solar eclipse occur in? What occurs when the moon blocks the earth from the sun?

What occurs when the earth casts a shadow on the moon? Sketch the correct position of the earth, sun and moon during a lunar eclipse. Sketch the correct position of the earth, sun and moon during a solar eclipse.
