Answer:
The Earth rotates on its axis at a constant tilt.
Earths rotation on its axis at a constant tilt provides seasonal changes in the different part of the country. This resulted to the distribution of the heat of the sun from northern hemisphere and to southern hemisphere. Making areas with hot temperature may experience rainy season in a year. This will help production of crops or food supply and water supply available for living organism.
If the Earth's rotation is not tilted, then both the northern hemisphere and southern hemisphere will be covered with thick ice sheet. The equatorial region or near the equatorial region will experience tremendous warm temperature. Making our life on Earth not ideal for living.
Magnetic Field
Earth is protected by the magnetic from the dangerous radiation coming from the heat of the sun.
Water and oxygen
These two elements are essential for living organism in order to survive. The existence of waters proves that Earth temperature is conducive for living.
Although there is alot of water on earth some of it is contaminated and could be harmful for us to drink .Therefore people don't drink it in order to not get sick.
