This type of space junk does not burn up in our atmosphere.

65 million years ago a disaster happened, although we are not sure of the cause. All the dinosaurs and many other groups of animals and plants became extinct around this time. The most popular theory is that a mountain-sized meteorite hit the Earth, throwing up a thick cloud of dust and causing tidal waves and global forest fires. The dust hid the Sun. This might have killed many plants, which need light to live. It might also have cooled the Earth and so killed the dinosaurs which, being unable to keep themselves warm, might have stopped moving and so starved.

Small Stars like our sun end their life as a _________ then a _________.

slide18

How long a star lives depends on

slide19

400a

The original mass of the star.

slide22

100

The Earth moves from daylight to darkness once every day due to fact that it is

slide23

100a

Rotating

http://www.nasa.gov/worldbook/wbkids/k_dayandnight.html

slide24

200

The Earth will make one trip around the sun each year. This movement is called

slide25

200a

Revolution

Earth is farthest from the Sun at its aphelion (summer in the Northern Hemisphere) and closest during its perihelion (winter in the Northern Hemisphere).

slide26

300

In which direction do both the Earth and Moon rotate and revolve

slide27

300a

Counter-clockwise

slide28

400

In the spring and fall the sun is directly over _______

slide29

400a

The equator.

It is overhead at the equator during the Spring and Fall equinoxes. The Sun is overhead at the Tropic of Cancer on June 21. This is the furthest north that the strongest rays will travel. It is overhead at the Tropic of Capricorn on December 21.

http://www.mhhe.com/earthsci/geology/mcconnell/earths_climate/intro.htm

slide30

500

The three reasons for the seasons are

slide31

500a

The tilt of the Earth, revolution around the sun, direct/indirect light that reaches Earth’s surface. ***Notice how the location of the most direct rays change as the Earth revolves around the sun.

slide32

100

What conditions are necessary for a spring tide to occur?

slide33

100a

The positioning of the sun and the moon also has an effect on the height of the tidal swell. During a new or full moon phase, the sun and moon are in line, pulling on the earth\'s surface. This creates a higher level of tide - called the "spring tides" from the Welsh word "springan" meaning \'to bulge\'.

What percentage of the moon is always illuminated?

The image is a model of ??

http://csep10.phys.utk.edu/astr161/lect/time/eclipses.html

slide37

300a

Solar Eclipse. A solar eclipse can occur when there is a new moon. This does not occur every month because the moon\'s orbital plane doesn\'t "lie flat" along the ecliptic, but forms an angle of about 5º as you can see in this diagram (note: the distances in this diagram are not to scale).

The phases of the moon are due to ________

slide41

500a

The position of the Earth, Sun, and Moon.

**Light on right, moon is getting bright.

slide42

100

The unit of measurement that scientists use to measure distances in space.

slide43

The closest star to the earth, not counting our own sun, is Alpha Centauri. This star, our solar system\'s closest stellar neighbor is 4.3 light years away from the earth! This means that the closest star to the earth (besides the sun) is >>>> 23,462,784,000,000 miles away from us!

100a

Light years

Distances in space are huge and if we used miles or kilometers our data (numbers) would be huge. One light year is equal to an extremely long distance - 5,865,696,000,000 miles to be exact!

Galaxies are classified by ??

Their shape. The Milky Way Galaxy is a spiral galaxy.
