1. (i) There is a regular unidirectional wind from the sea to land. It helps in flying the kite high. (ii) The wind is cooler and provide comfort to kite flyers even in bright sun.

  2. Atmosphere of Earth is a bad conductor so acts as a temperature buffer. However, moon lacks an atmosphere around it. Therefore, moon gets heated up as sun rays fall on its surface. It cools down drastically when there is no sunlight, causing wide fluctuations in its temperature.

  3. The composition of gases such ds CO₂, N₂ and CO₂ remains same in atmosphere due to the process of biogeochemical cycles. During these cycles occur the repeated circulation of biogenetic nutrients between abiotic and biotic components of the environment.

  4. Most of these elements first enter plants. and become components of organic material during the process of photosynthesis. Thus, they enter from air (CO₂), water (H₂O) and ions (N, S, p) from the soil. Form plants the chemicals pass on to other organisms through the food chains.
