Understanding the Greenhouse Effect
The atmosphere is a layer of gases that surrounds the Earth. It is made up of several different gases, including nitrogen, oxygen, and carbon dioxide. The atmosphere is divided into several layers, each with different characteristics. The layer closest to the Earth's surface is called the troposphere, and it is where weather occurs.
The atmosphere plays a crucial role in regulating the Earth's temperature through the greenhouse effect. The greenhouse effect is a natural process that occurs when certain gases in the atmosphere, such as carbon dioxide and methane, trap heat from the sun. This helps to keep the Earth's temperature within a range that is suitable for life.
However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and global warming. This is causing changes in the Earth's climate, including rising sea levels, more frequent and severe weather events, and changes in ecosystems.
In order to understand the greenhouse effect and its impacts, it is important to have a basic understanding of how the atmosphere works.
