How are volcanoes formed?



Volcanoes are natural phenomenon that occurs everywhere, but some places are more then others. The molten rocks and gases in the mantle called magma pushes its way upwards and pours to surface through cracks in the crust. This is a volcano. There are different types of volcanoes; some are explosive others are not, and all erupt as spectacularly as we see on the television. Some eruptions take place unexpectedly, but others can be predicted, which is very important for the people near a volcano.

How are new seas formed?

How are new seas formed?     Seas arise at place where the Earth's crust cracks open due ti expansion.Around 200 million years ago the Atlantic was formed in this way. Today in Earth Africa,a crack from Malawi to Ethiopia has formed as a result of the eruption of a volcano. If the soil sinks further, water from the oceans will enter  the region to give rise to a water body. this has already happened in the case of Red sea, the continuation of the east African rift system. If the plate continues to expand,then at some point of time it breaks completely giving rise to a long mid-ocean volcanic ridge.                                                                                                                                                           If you like this blog comment down below.

What Do Plants and Animals need to grow?

What Do Plants and Animals need to grow? Almost all plants and animals need air, water, light, and nutrition to grow. Green plants use a complicated chemical process, called photosynthesis, to create energy for survival and growth. Since plants create their own energy, they are the first link in the food chain. Animals need to drink water and eat plants or other animals to get energy. Therefore, they are present at the next step in the food chain. There are some animals, like camels, that can survive for days without drinking water, Since they live in deserts with very little water, they have adapted to the special condition of their habitat.

How many plates does the Earth's crust have?

How many plates does the Earth's crust have? The relatively solid earth's crust and a part of the layer that lies below it-is divided into seven large and more than smaller plates. These plates float over the hot , viscous layer, which is constantly in motion-like boiling soup. These flushes of heat in the Earth's interior are known as 'convection cells' at places where the convection currents push the rocks upwards , the crust often breaks and gives rise to a new crust. For example, the mid-ocean ridges in the Atlantic and Pacific oceans.           If you like this blog please comment down below                                                                                                                                       Read  the  previous  Blog : https://ourearthintheuniverse1.blogspot.com/2020/05/did-earth-always-look-as-it-does-today.html
