Detailed explanation-1: -What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Detailed explanation-2: -The availability of liquid water is the most important factor that makes a planet habitable, because water is a very effective polar molecule and hence an excellent solvent and facilitator for the complex chemistry of life.
Detailed explanation-3: -Carbon Dioxide (CO2) + Sunlight + Water in plants makes Oxygen and Food! During photosynthesis, energy from the sun and carbon dioxide are converted into chemical energy that the plant can use for food. As a result, oxygen is also created. This is used to power life.
Detailed explanation-4: -Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
