Final answer:
The blanket of gases surrounding the Earth is known as the atmosphere, which includes several layers, with the troposphere being the lowest. It consists mainly of nitrogen and oxygen, and it plays a key role in temperature regulation through the greenhouse effect.
Step-by-step explanation:
The term that describes the blanket of gases surrounding the Earth is the atmosphere. This layer extends over three hundred miles above the Earth's surface. It is composed mostly of nitrogen (78%) and oxygen (21%), with traces of argon, carbon dioxide, water vapor, and other gases. The atmosphere can be divided into several layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The troposphere is the lowest layer and is where most of our weather occurs. One of the crucial functions of the atmosphere is its regulation of Earth's temperature through the greenhouse effect; gases like carbon dioxide trap heat, warming the lower layers of the atmosphere. The atmosphere is the blanket of gases surrounding the Earth. It is made up of a mixture of gases, including nitrogen, oxygen, carbon dioxide, and water vapor. The atmosphere plays a crucial role in regulating the Earth's temperature and protecting life on the planet.
