Understanding Environmental Issues: Causes, Effects, Solutions
Environmental Issues: Causes, Effects, and Solutions
We must be conscious of environmental problems such as overpopulation, deforestation, endangered species, pollution, hunting, and overfishing, because they contribute to global warming.
Deforestation and Its Impact
For instance, deforestation leads to the destruction of rainforests, wiping out many animals and fish. Rainforests help control global warming because they absorb carbon dioxide. In recent years, large areas have been destroyed as trees

Subduction Zones: Collision Between Plates
Subduction of Oceanic Lithosphere Under Oceanic Lithosphere
The result is the formation of a deep oceanic trench. When the subducting plate is partially melted in the mantle, magma originates. Part of it rises to the surface through cracks and reaches the subducted plate, forming an arched archipelago of islands with great volcanic activity.
Subduction of Oceanic Lithosphere Under Continental Lithosphere
This phenomenon produces an active continental margin

The Model of Convection
He believed that the mantle was smooth and capable of convection currents pushing from below the lithospheric plates, which float. The hot and less dense material of the lower mantle would rise to the surface areas of the lithosphere, and as the material cooled, it would sink back down to the mantle zone where it would heat up again. The areas where convection currents rise would coincide with the ridges, and the areas where they decrease would coincide with subduction zones.

The classical methods of estimating ore reserves are:
Arithmetic Average Method
The contours are plotted on the plans or vertical projection. The area defined is determined by a planimeter or other method. The average thickness is estimated by the simple or weighted arithmetic mean. The average content and the density are determined in the same way. The body part between the inner and outer contour is generally calculated independently because the resources of this area are reported in a lower category.

Jet Streams and Atmospheric Circulation
A jet stream is a set of winds within the atmospheric circulation at high altitude, blowing east to west in the same direction as the Earth rotates. These winds can exceed speeds of 500 km/h at heights of 1200 m. The name ‘jet stream’ reflects its shape and intensity. There are two jet streams in each hemisphere.
