Describe The theory of relativity .​

Explanation:

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.

Explanation:

It is separated to special and general relativity. Special relativity is based on two key concepts. First, the natural world allows no “privileged” frames of reference. As long as an object is moving in a straight line at a constant speed , the laws of physics are the same for everyone.

Second,  light travels at an unvarying speed of 186,000 miles a second no matter how fast the observer is moving.

General relativity is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
