Transcript of The Himalayas
The Himalayas were formed by the collision of the Indian Plate and Eurasian Plate. 60 million years ago, India was an island by itself but it then started moving northwards toward Asia. When the plates finally collided (10 million years ago), the Indian Plate went underneath the Eurasian Plate and pushed the land up to form the Himalayas. We call this subduction. It's thought that Asia's soil was softer and less dense than India's which explains why the Indian Plate went underneath, not the other way around.
India is still moving northward to this day which means that the Himalayas are continually rising. However, erosion and weathering is also lowering it down at the same time.
For a better explanation, watch the video in website below:
What natural disasters occurred here?
There are many natural disasters that have occurred in the Himalayas. They include earthquakes, landslides, floods, forest fires, cloudbursts and avalanches.
Earthquakes - caused by the penetration of India going into Asia.
Landslides - masses of Earth or rock collapse from a mountain or cliff. They are common in hilly states of India such as Malpa where 380 people were killed from a massive landslide
Avalanches - many occur in the Himalayas where many people have died. An avalanche occurred this year on the 18th of April killing 16 climbers.
How does the climate affect human activities?
Mountains are a beautiful place where the height and scenery can take your breathe away. However, there are lots of reasons why humans do not live in mountains.
The two different seasons in the Himalayas are Summer and Winter. In Winter, temperatures are very cold and it is always snowing. Very few plants and animals live there because of the harsh weather and cold temperatures. That and animals that do live there have to adapt to the conditions.
Living high up in a mountain would also mean that it would be harder to breathe because the air is thinner.
The climate of a mountain greatly affects human activities because cold weather means no crops, no food no money.
This Mountain diagram might give you a better idea about climates in the Himalayas.
How does the height and steepness of the Himalayas affect human activity?
The height and steepness of any mountain, not just the Himalayas, would greatly affect human activities.
How does the mountain environment affect the standard of living of its inhabitants?
As we have talked about already, transport, the height and the weather would lessen the standard of living in the Himalayas. However, there are even more reasons to support that.
We could assume that most people living in the Himalayas would be generally poor because how are they supposed to make money? Sure, you have the tourists, the recreational sites and farming but even farming is limited due to climate and weather.
Facilities is another thing that would lessen the standard of living in the Himalayas. You can't just go to your local supermarket to buy food, clothes or other equipment you need. There would also be no hospitals so that would be a disadvantage. If you broke a bone or hurt yourself it would take a long time for you to get any medical attention.
Firstly, transport would be hard to achieve as we simply cannot drive from one side to another without any roads. Roads would be hard to build on mountains because they would have to wrap around the mountain and slowly raise in height. That would take a lot of time, effort and money.
Don't forget that mountains are also usually rugged and covered with forests, animals and sometimes even ice, snow and glaciers. This would be another hurdle to overcome.
Lastly, making a living on a mountain would be hard since farming and growing food cannot be done on a steep part of land.
