Answer:
According to the nebular hypothesis, our solar system is formed from a huge rotating cloud made mostly of helium and hydrogen.
Explanation:
The nebular hypothesis was proposed by I. Kant. It explains the formation and evolution of the Solar System. It is considered and accepted widely. The theory states that the Solar System was formed from a nebulous material. And as per nebular hypothesis, stars create the huge, dense clouds of molecular hydrogen. This hypothesis tries its best to describe the formation of the solar system from a nebula cloud that was made of a collection of dust and gas. It is also believed that the sun, planets, moons and asteroids were also born around the same time that is, around 4.5 billion years ago from a nebula.

We can deduce here that the arrow on the map that points to an air mass moving toward a cold front is: H 1029 - 1018
<h3>What is cold front?</h3>
Cold front actually refers to the boundary that shows a mass of cold air advancing. It goes towards the sector of a low-pressure.
We see that the arrow that is moving from the region of high pressure to the region of low pressure and has blue lines is the answer.

<span>Flow maps show how objects move between different areas. They are a type of thematic map, which look at a particular theme or topic. Flow maps often represent movement of goods or weather processes. A physical process that is commonly represented on and tracked by such maps is wind patterns.</span>
Answer:
The magma moves upward and erupts to form either an oceanic ridge or a hot spot volcano. At subduction zones, volatile compounds (especially water) escape from the subducting plate and lower the melting temperature of the overlying mantle rocks. This triggers melting and magma forms as a result.
