Weather
Weather is the day-to-day condition of the atmosphere at a specific place, including changes in temperature, rainfall, and sunshine.
Climate
Climate refers to the average weather conditions of a large area measured over a long period of time, usually 30 years or more.
Atmospheric Pressure
Atmospheric pressure is the pressure exerted by the weight of air on the earth's surface, which decreases as we go up to higher altitudes.
Humidity
Humidity is the amount of water vapor present in the air at any given time, making the air feel dry or damp.
Precipitation
Precipitation is any product of the condensation of atmospheric water vapor that falls under gravity, including rain, snow, sleet, and hail.

Frequently Asked Questions
What is the difference between weather and climate?
Weather changes day to day and can vary within hours (like a sunny morning turning into a rainy afternoon), whereas climate is the average weather pattern of a region studied over many years.
Which instrument is used to measure rainfall?
Rainfall is measured with an instrument called a rain gauge, which collects and measures precipitation in millimeters.
Why does air pressure decrease at higher altitudes?
Air pressure decreases as you go higher because there is less air above you pressing down, and the air molecules become less dense.
