Answer:
Plate tectonic, sediments erosion and volcanic eruptions are responsible for the natural characteristics of Canada.
Explanation:
Canadas natural characteristics occurs from the natural processes such as plate tectonics which started more than 3 billion years ago. Erosion of sediments occurs through storms and floods etc that is responsible for formation of plain regions of Canada. Volcanic eruptions also occurs in Canada that leads to the land formation so we can say that plate tectonic, sediments erosion and volcanic eruptions are the ways that is responsible for the natural characteristics of Canada.
The northeast region is the smallest by area of all regions in the United States, but by no means it is lacking in natural resources, it is in fact a place very rich in natural resources.
In this part of the country there's an abundance of iron ore and coal which are very important for the industry.
It also has a very high quality soil, and because of that it has an abundance of agricultural products like the corn. apples, potatoes, different types of berries.
The timber is in abundance as well, as there is lot of densely forested parts.
The region is also very rich in seafood, especially eels and clams.
The groundwater is the largest freshwater reservoir on Earth in liquid form. These waters though are not isolated from the rest of the freshwater, but instead they are connected with the streams, thus they affect them heavily.
The groundwater has been heavily used in the last century, and it has been depleted. The depletion of the groundwater has been the result of over usage, or to put it simple, more water has been extracted than what naturally is replenished.
This has been causing more and more problems. Apart from the groundwater resources getting depleted and than be unusable, the depletion of their water has resulted in lowering of the level of water of the streams, as the streams have been receiving less and less water. Also, because there is much less water and it mixes with lot of ground and rocks, the water quality has been becoming worse and worse, and if this trend continues it can have devastating effects.
I am guessing the US because we have NASA and we won the space race-plus every day we hear in the news that NASA just discovered new stuff about asteroids.
hope that helped
