Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
Answer:
Wind Shear is the difference in direction and speed of the wind in the atmosphere within a specific distance.
Explanation:
Eddies are generated when winds goes over a mountain creating vertical shear on the side that is sheltered from it, that creates air pockets causing atmospheric turbulence know as "rotors".
The change of direction and wind speed with altitude variation is called Vertical wind shear.
The change in wind speed together with a change in lateral position at a certain altitude is called Horizontal wind shear.
One scenario is a mountain with down-bursts and micro-bursts creating ice crystal plumes clouds that could warn pilots of wind shear, allowing then to avoid accidents.
Honestly none of them. It should be 5.098 x 10^6
