The appropriate answer is c. the solid phase, liquid phase and gas phase of a substance. A phase diagram is used to represent the phase or physical state of a substance at a given temperature or pressure. Pressure is represented on the y axis while temperature is represented on the x axis. Phase diagrams are used in areas such as Physics, Chemistry, Engineering, Mineralogy and Material Science.

climate

Changes in the composition of the atmosphere have caused gradual changes in earth's <u>climate</u> throughout history, causing changes in plant and animal life that contributed to mass extinctions.

The following are some of the reasons:

UV light
climate
pollutants
hydrofluorocarbons

heat

The surface of the Earth warms up as sunlight strikes it.
Surface-emitted infrared light is absorbed in the atmosphere and transformed into heat.
The temperature close to the surface rises as a result of this heat being trapped in the atmosphere.

<h3>UV light:</h3>

indirect impacts of climate change on UV radiation from the surface.
By changing the concentrations of ozone, UV-absorbing tropospheric gases, aerosols, and clouds in the atmosphere, climate change may have indirectly affected UV radiation levels in the past.
These influences are probably going to persist in the future.

<h3>climate:</h3>

People are at risk from food and water shortages, greater flooding, high heat, an increase in disease, and economic loss due to climate change.
Conflict and human migration are potential outcomes.
Climate change is the top hazard to world health in the twenty-first century, according to the World Health Organization (WHO).
