a) Mention the names of two microscopic particles in the atmosphere which are referred to as “aerosols”. b) Name the two most important factors affecting the atmospheric pressure of a place. c) What are the two most common forms of precipitation? d) Name the two commonly used scales for the measurement of temperature. e) State any two sources from where we get the weather forecast
Answers
a.Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air.
b.The 3 main factors that affect barometric (air) pressure are: Temperature. Altitude or Elevation. Moisture ow water vapour.
c. The most common types of precipitation are rain, hail, and snow. Rain is precipitation that falls to the surface of the Earth as water droplets.
d. The two most common temperature scales are the Fahrenheit and Celsius (Centigrade) scales
e.The science of forecasting the weather gets better as new weather satellites are launched into orbit and technology improves. Meteorologists rely on data from satellites, and airplanes, and devices dropped from airplanes or weather balloons.
