The main characteristics that scientists use to divide Earth's atmosphere into layers are elevation and pressure.

The main characteristics that scientists use to divide Earth's atmosphere into layers are temperature and composition, elevation and pressure, and amount of ozone and other gases.

Temperature and composition: The first characteristic that scientists use to divide Earth's atmosphere into layers is temperature and composition. The atmosphere is divided into layers based on changes in temperature with altitude. The different layers have different temperature profiles due to various factors such as absorption of solar radiation and temperature inversion.

Elevation and pressure: Another characteristic used to divide the atmosphere into layers is elevation and pressure. As you move higher in the atmosphere, the pressure decreases. Scientists use these pressure changes to define different layers. For example, the troposphere is the lowest layer, where most weather occurs, while the stratosphere is the layer above it.

Amount of ozone and other gases: The amount of ozone and other gases also play a role in dividing the atmosphere into layers. The ozone layer, located in the stratosphere, is a layer with a high concentration of ozone molecules. The presence of this layer is important as it absorbs most of the Sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface.

So, the correct answer is a combination of temperature and composition, elevation and pressure, and the amount of ozone and other gases.
