Global warming is the phenomenon of gradual increase in temperature near the Earth’s surface. This phenomenon has been observed over the past one or two centuries. This change has disturbed the climatic pattern of the earth. However, the concept of global warming is quite controversial. But, the scientists have provided relevant data in support of the fact that the temperature of the Earth is rising constantly.

There are several causes of global warming which have a negative effect on human, plant and animal lives. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negatives of global warming.

The sun is the most perfectly round natural object known in the universe, say scientists who have conducted precise measurements of its dimensions. As a spinning ball of gas, astronomers had always expected our nearest star to bulge slightly at its equator, making it very slightly flying-saucer shaped. To the eye, the moon appears round, and it's natural to assume that it is actually spherical in shape – with every point on its surface equidistant from its center – like a big ball. Not so. The shape of the moon is that of an oblate spheroid, meaning it has the shape of a ball that is slightly flattened. 

Stars are star-shaped because of imperfection in our eyes

Most stars are much like the Sun—giant balls of gas burning billions of miles away. These spherical stars pump out a steady stream of light that crosses vast stretches of space before it illuminates the night sky.

Seismograph is an instrument which measures and records the magnitude of an earthquake in terms of the shock waves it produces. The instrument is simply a vibrating rod, or a pendulum, which starts vibrating when tremors occur.  A pen is attached to the vibrating system. The pen records the seismic waves on a paper which moves under it.  By studying these waves, scientists can construct a complete map of the earthquake.

Chain pump: A chain pump consists of two large wheels, connected by an endless chain. The bottom wheel is half immersed in the water source. As the wheel is turned, the connected buckets dip into the pool and pick up water. The chain then lifts them to the upper wheel, where the water from the buckets is transferred to the pool. The chain then carries the empty buckets back down to be refilled and the process continues.

Moat or pulley-system: It is a manual irrigation method. By this method water is directly taken out of wells with the help of pulley and is used to irrigate fields.
