Acceleration is non zero but the velocity is zero.
Answer: Option 2.
<u>Explanation:</u>
Acceleration is the speed that an object gains with in a short period of time. In the language of Mechanics, Acceleration is the change in the velocities of the objects with respect to the time. So when a ball is thrown up in the air, there will be some acceleration and there will be some speed that the ball will gain when thrown up.
Velocity is the speed of an object but in a particular direction. Velocity of an object is the rate of change of the position of the object with respect to the frame of reference of that frame. So the velocity of the ball up in the air is zero.

Climatology is a subspeciality of environmental science. The correct option among all the options given in the question is option "B". Climatology is actually the scientific study of climate. The role played by the clouds is an important part of the study of climatology. This is a modern field of study that can easily be considered as a part of physical geography or earth sciences.Some of the famous early climate researchers include Edmund Halley, Benjamin Franklin, Francis Galton and Helmut Landsberg.
