Case Based Questions
Read the given excerpt and answer the questions that follow:
If the news says that a particular place received 30 mm of rainfall in a day, what does it mean? How is rainfall measured? The amount of rainfall is measured with the help of an instrument called a rain gauge. When it rains, the water falls into a funnel and is collected in a cylinder. A scale is attached to the cylinder to measure the depth of rainwater collected. For example, when the height of the water collected is 5 mm, we say that the area received 5 mm of rainfall.
(a) Which instrument is used to measure rainfall?
(b) How is the rainfall measured?
(c) Which part of the instrument displays the depth of water?
(d) Can we make this instrument and measure the rainfall ourselves?
