Answer 1

1. . because of the right distance from the sun the right temperature range the pressure of water and suitable atmosphere and a blanket of ozone

2. because more than half of our planet covered with water .

3. it does do because the earth is round and spins on the axis . which is slightly tilted .

4. mass independent upon gravity but weight depend upon the gravity . so we can say that the mass of an object remains constant at all places but weight do not constant it changes due to changing of places
