Answer:
The correct answer is: A) Asteroid belt.
Explanation:
All of the other events can be explained by colliding worlds in the early solar system but the asteroid belt can't. The asteroid belt originated from the primitive solar nebula as a congregation of planetesimals, which were the precursors of the protoplanets.
Answer:
Theory
Explanation:
A hypothesis is a prediction made from limited evidence as a starting point for further investigation.
Answer: As altitude increases, atmospheric pressure decreases
Explanation:
Atmospheric pressure 
is defined as the force 
per unit area 
the air that forms the atmosphere exerts on the Earth's surface:
It should be noted that as the altitude increases less air is above and, therefore the air weights less. This is because the atmosphere losses density as we ascend, causing less air.
However, it is important to point out this decrease in pressure is not linear, since at the beginning (in the first kilometers above sea level) it reduces more rapidly than in the next kilometers above. That is why this relationship between atmospheric pressure and altitude is exponential.
