Around 4.5 billion years ago the solar system was formed by a cloud of dust, hydrogen, helium and other gases. they were part of a bigger cloud called a nebula. This cloud was pulled by gravity and collapsed. A circular material was created around, the pressure of this material created energy and formed the Sun.
<u>A nebula</u> is the first step in the formation of the solar system
Answer: Option B
<u>Explanation:</u>
Solar system was formed several years ago from a solar nebula. A nebula is nothing but a cloud of dust and gas. The nebula was acted upon by the gravity. This led to the collapse of the nebula and it started to spin with all its materials in it.
As the spinning increased, more and more small particles were drawn in and bound by the ''force of gravity''. This resulted in the formation of a ''star'' and ''disk material'' for the formation of planets.
The Amazon rainforest plays an important part in regulating the world's oxygen and carbon cycles. It produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink, meaning it readily absorbs large amounts of carbon dioxide from the atmosphere.
To deplete freshwater consumption of the water must be greater than the renewal rate. If the precipitation collected it does not mean it depleted, it can be still used later on.
There are many ways in which you can help conserve nonrenewable resources. You <span><span>could conserve nonrenewable resources by not using them. Hope it Helps
