Climate change - Explanatory Note

                                        Climate change

Climate change refers to long-term shifts in weather patterns and global temperatures. It is primarily caused by human activities and natural processes. It has significant impacts on the environment, ecosystems and human well-being. The primary driver of climate change is the increased concentration of greenhouse gases in Earth’s atmosphere. (English for Class Nine by NCTB)

The greenhouse gases trap the sun’s warmth which makes our planet warmer. One of the major causes behind it is cars and factories giving off these gases. Besides, we are also cutting down trees indiscriminately that makes it worse, as trees absorb these gases. Because of climate change, the weather is getting worse gradually. Some parts of earth get too hot and in other parts, it might rain a lot. Nature, animals and people all suffer from these changes. 

Water Cycle - Explanatory Note

                                                     Water Cycle

The water cycle is a continuous process through which water circulates through the earth. It involves several stages that help to maintain the balance of water distribution. Water is constantly recycled to sustain life and support various ecosystems. Firstly, the sun’s heat causes water from oceans, lakes and rivers to evaporate, turning it into water vapour. Secondly, as water vapour rises into the atmosphere, it cools down and condenses into little droplets, forming clouds. When the water droplets in clouds become too heavy, finally, they fall to the ground in the form of rain and snow. After that, the rainwater that is not absorbed in the ground and by plants flows over the land as runoff. It flows to rivers, and streams and eventually makes its way back to the oceans.
