Answer:
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Answer:
to provide a reference system
Explanation:
The equator and prim meridian used on maps provides a reference system for determining location and navigating the earth.
- An equator is the only line of latitude that is a great circle.
- Prime meridian is a line of longitude that is 0°
- When both are used, they can form the basis of a reference system to determine places on earth.
- Using these lines, we can assign values of coordinates to the earth surface to facilitate location determination.
The equator and prime meridian are used on maps to provide a reference system.
Wind erosion is the main cause. And since it is the desert that wind can pick up tiny sand rock particles that slowly grind against the rock. Over time the erosion will give a jagged rock the smooth features as if it had been submerged in a river for the roughly same period of time.
Answer:
Coriolis effect
Explanation:
The Coriolis effect is originated from the force that is generated due to the rotation of the earth. This is commonly known as the Coriolis force. This force is responsible for the formation of clockwise and anticlockwise wind patterns in the northern and the southern hemisphere respectively.
There are various convection cells that are formed in different regions on earth. As the wind blows from a region of high pressure to a region of low pressure, on a large scale, and at the same time, the earth also is rotating, so its path gets curved or bends, due to the effect of Coriolis force.
Thus, the apparent bending of the wind while blowing from one place to another is called the Coriolis effect.
Answer:
A - Pacific plate
B - North American plate
C - African plate
D - Eurasian plate
Explanation:
Plate tectonics theory explained the plate movement and evolution from 65 million years ago which is pre cambrian era. There were seven major plates in the world such as Pacific plate, North American plate, South American plate, Eurasian plate, African plate, Indo Australian plate and Antartic plate. There were three movements in the plate such as Convergence plate boundary, divergence plate boundary and Transform plate boundary. Pacific plate is biggest plate among all.
