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.
Answer:
2. Mountain Ranged
Explanation:
Orogeny is the primary mechanism by which mountains are formed on continents. An orogeny is an event that takes place at a convergent plate margin when plate motion compresses the margin. This leads to both structural deformation and compositional differentiation of the Earth's lithosphere.
Ecozone is
divergent environment wherein the biotic community, plants, animals and people
and non-biotic community, lithosphere, atmosphere and hydrosphere communicate
and process.

Hence, Conservationists
that are inclined and supports the proper usage of the natural resources are
able to identify areas and resources that are being misused. They are also able to prevent and report such possible threats to the environment and helps maintain and sustain the ecological system. This will increase the chances to avoiding climate change to a great extent.
