Climate refers to the long-term patterns of temperature, humidity, wind, and precipitation in a specific area. It is influenced by various factors, including geographical location, altitude, and ocean currents. Different regions experience distinct climates, such as tropical, arid, temperate, and polar, which affect the local ecosystems and weather conditions. The atmosphere plays a crucial role in shaping climate by trapping heat from the sun and regulating temperatures. It consists of layers of gases, including nitrogen, oxygen, and carbon dioxide, which are essential for life. Changes in the atmosphere, such as increased greenhouse gas emissions, can lead to climate change, impacting weather patterns globally.
