Answer:
1 ) The Meteorological Department prepares a weather report in which all the weather information is plotted on the maps.
2 ) The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. ... The top of the rain gauge is 0.3m above the ground.
3 ) Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity.
4 ) 1 ) Red-eyed frog has developed sticky pads on its feet which help it to climb easily on the trees on which it lives. The sticky pads on feet also allow the red-eyed frog to attach itself to the branches and leaves of the trees. 2) The big and bulging bright-red eyes of this frog are an adaptation for protection.
5 ) any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment. a form or structure modified to fit a changed environment.
6 ) Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun. What causes weather? ... These differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.
