Weather is a complex phenomena. in order to solve engineering problems such as the prediction of weather, we utilize degrees of freedom (DoF)... weather is one of the many elements that need millions of DoF and still cannot accurately predict it. mainly it's a vector analysis much akin to finite element analysis where each micro degree of freedom or say molecule of air is represented as one point interconnected in a web of points and each point's properties are altered relatively (similar principles how autonomous mini drones coordinate synchoronously) to each other.
many factors are considered: pressure, temperature and density of the air for sure. friction factors. drag factors. rotation of the earth. and that's the natural phenomena. include the heat given off the land, the radiation from the sun, airplanes, people, etc... its highly complicated. having done a weather station project, it's fair to say that there isn't a simple answer to your simple question. we measured wind direction, wind current, temp and humidity, visibility, pressure, etc... and we couls measure these things, but can't really say why say the wind went east or west... except tell you that its because of millions of degrees of freedom interacting with each other simultaneously and some things like weather are just like that.
<span>Without the protection of the stratospheric zone, the UV rays can cause skin damage over a prolonged duration in the sun. If this happens the risk for skin cancer is increased. It's best not to be out in the sun for any long period of time between the hours of 10:00 a.m. to 2;00 p.m. when the ultraviolet rays of the sun are strongest.</span>
The correct answer is B. Less arable land. Arable land is the main reason why the land is cleared. Arable land is the land that is suitable for ploughing and of sufficient quality for growing plants. So for this reason, the forests are cleared (by cutting the trees and bushes) and more land for agriculture is gained.
<span>As water in the oceans cools down, it tends to Sink b)Sink Because when water becomes warm due to the heat of the sun it floats to the surface of the ocean and cool water is in the bottom</span>
