<u>ANSWER:</u>
Collisional plate boundary led to the 'creation' of the Himalayan Mountains.
<u>EXPLANATION:</u>
- Himalayan Mountains have been form bed because of the 'collision' of the 'Indian Plate' and the 'Eurasian Plate'.
- The collision process of the plates started almost '50 million years ago' and continues till date.
- The Indian plate is a major tectonic plate in the eastern hemisphere.
- The Eurasian plate and the Indian plate collide along the 'boundary' between 'India and Nepal' led to the formation of the Himalayan Mountains.
- The Indian Plate as well as the Eurasian Plate are moving till date causing the deformation and compression of both plates.
The correct answer is - A) Permafrost used to be permanent.
The permafrost used to be permanent until recently, so using certain techniques of building on it functioned properly. But with the climate changes that are becoming more and more evident, the permafrost is no longer permanent, but instead, it is either defrosting in some part of year and then forming again, or has been totally absent from some regions in the present.
That has caused changes in the rules governing building on permafrost. The reason for the changes is that the old techniques do not work properly anymore, and the permafrost changes are making change in the landscape, making big damages on the infrastructure in meantime.
Physical geography is the branch of geography dealing with the natural features and the processes
Plate tectonic is a scientific theory that says the Earth’s lithosphere is divided into several plates. The plates glide over the mantle. In early 20th century, this theoretical model builds on the concept of continental drift. It was first proposed by the scientist Alfred Wegener in 1912. After seafloor spreading was validated, the theory was accepted by the geoscientific community.
