2.hygrometer
3.precipation
4.equator
5.yiopjk
Explanation:
1.The thin ozone layer in the upper stratosphere has a high concentration of ozone, a particularly reactive form of oxygen. This layer is primarily responsible for absorbing the ultraviolet radiation from the Sun.
2.An instrument to measure the dew point, relative humidity, and vapor pressure. It essentially consists of two ordinary, accurate, mercury thermometers. One has thin muslin wrapped around it and is kept wet; it is called a wetbulb thermometer.
3.A barometer is an instrument used to measure air pressure. Air pressure is usually expressed in units of millibars (mb) or inches of mercury (in. Hg.). At sea level, standard air pressure is 1013.25 mb. or 29.92 in.

4.At the equator, the altitude is lower and also because of the direct heating of sun rays on the surface, the temperature is much higher than at the poles. This makes the air near the surface hot and lighter and hence it rises up which results in lower air pressure.
