Slide 1

About Earth The main known planet with a situation to bolster life.

Slide 2

What is an Axis? A pivot is a nonexistent straight line that partitions an item equitably. For a circle (like a ball or a globe) the pivot goes straight through the middle start to finish. For planets, the hub is the fanciful straight line that the planet turns around.

Slide 3

Earth\'s Axis The Earth\'s hub is NOT adjusted straight here and there. For instance, when an ice skater is turning she is pivoting on the hub that is straight here and there.

Slide 4

Earth\'s Axis The pivot of the Earth is TILTED at an edge of 23.5 degrees and turns at this edge. When you are simmering a marshmallow over a flame, the marshmallow is turning around the hub of the point of the stick.

Slide 5

Why do we have seasons? Pause for a moment and consider why the Earth encounters an adjustment in seasons. Record what you think causes the change of seasons. How about we consider this together and talk about our answers as we come.

Slide 6

Why do we have seasons? Here is a photo demonstrating Earth\'s circle around the sun from the side perspective of the elliptic way. Taking a gander at this chart, why do we have seasons?

Slide 7

Why do we have seasons? In the wake of seeing that chart, numerous individuals may figure that the seasons are brought on by how shut the Earth circles the sun. Pondering what number of seasons we involvement in one year, does the reason above bode well? No, on the grounds that if seasons were brought on by how shut the earth goes by the sun, then we would have two summers and two winters in one year!!

Slide 8

Why do we have seasons? Consider the possibility that we changed to a more precise point of view review the elliptic way from above. Presently what do think causes the change of the seasons?

Slide 9

Why do we have seasons? Presently a few people may figure that the seasons are brought on by the Earth\'s tilted hub. Considering the second graph of the Earth\'s circle, does this bode well? Yes, on the grounds that the measure of light we get changes following the Earth is pivoting at an edge. The point of the Earth\'s hub is confronting toward the sun in one position (summer) and far from the sun (winter) in another. There are two positions where the hub is not guiding towards or away, but rather is parallel toward the sun (fall and spring).

Slide 10

Poles and Equator What about the temperatures of the north and south shafts and the equator? The north and south shafts get less immediate daylight amid the year, so they have a much colder temperature. The districts around the equator get more straightforward daylight amid the year, so they have a much hotter temperature.

Slide 11

Types of Poles on Earth The Earth has two sorts of posts. The two sorts of shafts are geographic posts and attractive posts. These two sorts of posts are close to each other, however are not situated in the same spot!

Slide 12

Geographic Poles The geographic posts of the Earth are characterized as the areas where the Earth turns around its hub. They are found 90 degrees from the equator. The geographic north shaft is situated in the Arctic Ocean. The geographic south post is situated on Antarctica.

Slide 13

Magnetic Poles The attractive shafts of the Earth are characterized as the focuses where the attractive fields are the most grounded. They are near the geographic posts, yet are not in precisely the same. The attractive post in the north is found somewhat south of the geographic north shaft. The attractive shaft in the south is found marginally north of the geographic south post.

Slide 14

+ – Earth is a Magnet! Magnets have two shafts. One is sure and the other is negative. The attractive field lines stream from the negative to the positive post of the magnet. We can\'t really see the attractive field lines, however they can be measured.

Slide 17

Earth\'s Magnetic Field The Earth produces its own particular attractive field. Earth\'s attractive field goes about as a shield. It shields us from sun based particles that go through space as "sun powered wind". Life on Earth is conceivable on the grounds that the attractive field: shields us from exceptionally compelling conditions considers only the perfect measure of light and warmth to achieve the Earth.

Slide 18

Earth\'s Magnetic Field attractive field lines charged particles from the sun

Slide 19

The Northern Lights The Northern Lights is the wonder when shaded light is seen in the sky over the attractive post in the north. It is additionally called the aurora borealis, which is Latin for "northern first light". At the point when there are tempests on the surface of the sun, quick moving particles fly towards the Earth. These charged particles hammer into iotas and atoms in the furthest part of the Earth\'s environment and make hued light around 100 km over the Earth\'s surface.

Slide 20

Origin of the Northern Lights

Slide 21

The Northern Lights The light watched is always moving and evolving. It typically comprises of numerous greenish beams, framing long bends and window ornaments, which stretch like strips over the sky. A large portion of the Northern Lights are green, yet once in a while they have blue-green tinges or a blend of green and yellow. Red Northern Lights are to a great degree uncommon. An even rarer event is violet in the inside.
