Answer:
1. Interstellar cloud is an accumulation of dust and gas in between stars .
2 . The outer planets are composed of low density gas .
3 . Meteorites is the most important source for determining the age of our Solar System .
Explanation:
1 . Interstellar cloud
It is formed by the accumulation of plasma , gas and dust in the galaxy .
An interstellar clouds are more sense than the interstellar medium .
The cloud are classified according the size , density and temperature of the cloud . The interstellar cloud is formed by dust and gas particles from a red giant .
2 . The composition of the outer planets are from , the low density gases.
3 . Meteorites -
A meteorites originates from the outer space , and is a solid piece of debris . it can pass through the surface of a moon or planet , and due to high pressure and chemical interactions , can make the meteorite burn , and hence is seen as a shooting star or falling star.

-- If you go outside at the same time every night and look at
some familiar stars, you'll see each of them them move westward
at almost exactly 1 degree per night.
-- The reason for that apparent motion is the real motion of the
Earth in its orbit around the sun, at almost exactly 1 degree in
every 24 hours.
(average during a whole year is 0.9856 degree per day.)
Answer:
C, Northern and Western Hemispheres
Explanation:
We know that this is true because option A is completely incorrect since the Southern Hemispere contains south America, part of Africa, Australia, Antartica, and part of Asia. While the Eastern Hemisphere contains Africa, The Middle East, Asia, Europe, and Australia.
Based on the facts above, we can rule out A, B, and D, thus leading us to C!
Hope this helps! :)
