General Science Questions

Temperate Cyclones are cyclones of mid-latitudes and hence are primarily under influence of permanent winds of mid-latitudes i.e. westerlies. Their movement is therefore eastwards of their origin with average velocity of 32km per hour in summers and 48km per hour in winters.

Movement of Tropical CyclonesNormally, they move from east to west under the influence of trade winds because trade winds are permanent winds of tropical latitudes. The general direction is therefore westwards from their origin. They advance with varying velocities. Weak cyclones move at the speed of about 32km per hour while hurricanes attain the velocity of 180km per hour or more.

In the given options, all are the benfits of ozone. But, the main benefit of ozone is absorbing ultraviolet radiation from the Sun.

Non-renewable resources are those natural resources that are available in limited quantity.

These resources cannot be renewed or replenished in short duration.

Examples are :: Natural gas, Petroleum, Coal,...

Smallest particles of matter are known as quarks and leptons that seem to be the fundamental building blocks. This is too small to measure but bigger than 0. This is ofen consider as fundamental building blocks and something even smaller.

A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. A cold front usually bring the temperature down by more than 15 deg and heavy rainfall with thundering and lighting.
