Yet during an earthquake, you would surely get an idea that something is going on under the earth you walk on.
There is a lot of heat deep down inside the earth, which is why many houses use geothermal heating systems.
Through a geothermal heating pump will extract heat from under the ground and provide warmth for your whole house.
However, aside from machines using it, the heat under the Earth's crust is most visible when volcanoes erupt.
Many encyclopedias explain in details the working of a volcanic eruption, but what happens after that? A volcanic eruption brings about many changes in the overall environment.
Altogether, this may either be helpful for the environment or harmful.
However, it is a natural disaster, and you cannot do anything to avoid its adverse impacts.
Primarily, it is the air that is affected by an eruption.
All volcanoes may be different.
While some erupt with a massive jolt, others may be quiet.
With an eruption, a huge spell of gases leaks into the air.
These gases (mainly comprising of carbon dioxide, sulfur dioxide, hydrogen sulfide, carbon monoxide, hydrogen, and methane) are expelled into the atmosphere.
All these gases increase the likelihood of an acid rain.
With the eruption, tiny rock particles may be expelled into the air.
They occupy the space that was to be occupied by gas particles.
As a result, the air around the volcano is thick and suffocating.
Moreover, they have the ability to travel over long distances which makes them capable of taking these heavy volcanic gases all across the world.
Similarly, the ash particles in the air cause breathing problems in individuals.
These ash particles can form a thick layer on the areas in the surrounding.
When it is combined with water, they form a mud-like mass which is hard to remove.
Changes in the landscape around a volcano are massive.
When magma flows down the landscape, it takes everything along with it.
All the trees, plants, animals, buildings and roads which lie in the path of this lava are burnt.
When this lava cools, it forms a hard rock on the surface.
If the rain follows after the eruption, the water and wind will cause weathering of this rock and this will eventually turn into a fertile soil.
Plants, animals and humans are also affected by the eruption.
However, humans and animals are able to survive the changes.
The ash is bearable until it is hot or it covers the food.
However, trouble arrives when ash impedes water.
The harm is not only done to the marine life, but also to other animals and humans as water is the necessary element they need to survive.
In all, a volcanic eruption does much harm to the whole ecosystem, yet thankfully, neither does the eruption nor the effects of the volcano last long.
Therefore, it is not hard to survive after an eruption.
