The term "temperature change" refers to any alteration in the degree of hotness or coldness of a substance, environment or object. It is usually measured using a thermometer and can vary depending on various factors such as weather conditions, altitude, humidity, and geographical location among others. Temperature changes are often associated with seasonal variations, where temperatures tend to be higher during summer months and lower during winter months in most regions of the world. In addition, temperature changes can also occur due to natural disasters such as volcanic eruptions or human activities like burning fossil fuels which release greenhouse gases into the atmosphere leading to global warming.
