1st way is chopping trees for wood. 2nd would be pollution by fossil fuel.

Though initially designed for refueling, NASA plans to expand the capabilities of Restore-L to include other maintenance activities that will extend the life of an orbiting spacecraft. “Restore-L effectively breaks the paradigm of one-and-done spacecraft,” says Satellite Servicing Capabilities Office (SSCO) Associate Director Frank Cepollina in a prepared statement. Once deployed, the robot could act as a gas station in space, providing satellites with much-needed propellant. On the maintenance side, the robot one day may be able to manufacture and assemble components in space and use them to service a satellite. It also may be used to reduce space accidents by removing space junk from orbit.

Answer:
As given below.
Explanation:
1. <u>False</u>, as the number of daylight hours on the globe are mapped by the location f places over the various latitudes and altitudes. And the sun is not with the same both rise and set at both the hemispheres.
2. <u>Yes</u>, there exist changes of 12 hours in sunlight and darkness on earth due to the rotational speed of the earth on its axis as the earth is tilted 23.5 degrees so in both the hemisphere there exists equinoxes and solstices.
3. <u>True</u>, as the known fact the earth rotates in anticlockwise direction hence the eastern side gets to see the sun first and western side later this rule applies everywhere in the earth on both the equinoxes.
4. <u>True</u>, The celestial poles and equator are two points on earth that represent the equinoxes and the point that falls directly over the poles is called the zenith and the plane that touches is called the galactic plane.
