Answer 1

The following statements accurately describe the importance of the ozone layer and how it protects life on Earth:

The ozone layer is made of ozone molecules.
The ozone layer is found inside of the stratosphere.
Ozone blocks most of the ultraviolet radiation from the sun.
The ozone layer is a layer of the Earth's atmosphere that is composed of ozone molecules. It is located in the stratosphere, which is the layer of the atmosphere that is located above the Earth's surface and below the mesosphere. Ozone is a molecule that is made up of three oxygen atoms, and it is formed when ultraviolet (UV) radiation from the sun breaks down oxygen molecules (O2) into individual oxygen atoms, which then react with other oxygen molecules to form ozone (O3).

Ozone is important because it blocks most of the harmful UV radiation from the sun, which can damage living tissue and cause skin cancer. This makes the ozone layer an important protective layer for life on Earth.
