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:
The Milankovitch cycles in association with other natural factors explain how glaciers may advance and retreat over periods of d. ten thousand to one hundred thousand years.
Explanation:
The Milankovitch cycles -
This is the movement related to Earth's orbit around the Sun .
There are three cycles , Axial tilt , Eccentricity and precession .
According to this theory , these cycles together affect the amount of the solar heat that is incident towards the Earth's surface and the climatic pattern .
The Milankovitch cycle helps the advance and retreat of ice over the periods of 10,000 to 1000,000 years , but it does not explain the cause of Ice Age.
D. Since they have fertile land and temperature, they focus on agriculture which doesn’t allow them to grow alot
Answer:
A time zone is a region of the Earth that has adopted the same standard time (local time).
-Most adjacent time zones are one hour apart (although a few are 30 minutes).
-They compute their local time as an offset from Greenwich mean time (GMT).
