Answer:
Oceanic, Seafloor Spreading, Submarine Volcanic, Rift Valleys, Great african
Explanation:
DIVERGENT PLATE MARGIN (Also known as a constructive boundary or an extensional boundary)
Here two plates moves __away__________from each other. Molten rock, or magma, immediately rises to fill any possible gap and forms new <u>oceanic</u> crust. When this happens underwater, it is described as <u>seafloor spreading</u>. Huge underwater <u>submarine volcanic</u> ranges are formed from magma coming up from the mantle. Over time these submarine volcanoes may become large enough to reach the surface .eg. Iceland in the North Atlantic Ocean.
Where plates move apart on land, <u>rift valleys</u> are formed. An example of this is the <u>Great African</u> Rift Valley.
Answer:
As new seafloor moves away from an ocean ridge, the seafloor cools and becomes less dense than the material beneath it.

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.
