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.

They can maintain a government. They get raided by neighboring countries. They have ridiculous resources... Which is why they were constantly colonized. D is my answer.
The negative effects of geological structures in our environment can be landslides occurring on unfavorably oriented geological structures causing damage and sometimes loss of life on highways and railways, for example.A positive effect of geological structures is that where there are subduction zones, mineral deposits can form above them on the adjoining continents like in British Columbia on the west coast of North America. Also, faults and fractures can allow hydrothermal fluids charged with metals to form ore deposits.
