15 degrees (1 degree every 4 minutes)
The answer would be the Caspian Sea
South American and Nazca tectonic plate boundary;
The boundary between the South American and the Nazca plates is a vibrant one. These two plates have the same density, so they collide and lift the land upwards, which is why the Andean Mountain Range formed. Occasionally there are earthquakes and they can be very strong. This is a convergent boundary.
Indian and Eurasian tectonic plate boundary;
The tectonic between the Indian and the Eurasian tectonic plates is also a convergent one, where we have two tectonic plates with the same density pushing against each other, and thus lifting up the land, which is how the Himalayan Mountain Range was formed. The earthquakes are relatively rare, and are of different velocity.
Pacific and North American tectonic boundary;
The border between these two plates is a a convergent one as well, but the Pacific plate has a smaller density than the North American one, so it is subducting underneath it. This brings in a very big geological activity, so there's multiple volcanoes and volcanic activities, as well as a big amount of earthquakes.
Answer: A sharp increase in population around the world
Explanation:
Natural disasters such as flooding, land slides and mass wasting are closely related to the effects of creating room for an increasing population. The expansion of human habitation and industrialization put a lot of strain on the environment by depleting forests, altering the course of rivers for irrigation and pollution.
Natural disasters are accompanied by huge economic losses in the form of loss of property and disruption to business activities.
