Answer me guys​

Answer 1

Answer:

HOPEFULLY THIS ANSWER MAY HELP U

Explanation:

a) Rotation of the Earth is its turning on its axis. Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. The Earth's axis of rotation is tilted by 23.5 degrees.

b)Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

c)They are used in communication. They are used in weather forecasting system. They are used in GPS (Global Positioning System) They are used to transport instruments and passengers to the space to perform experiments.

d)Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.

Answer 2

(A)

• Rotation:

• Rotation of the Earth is its turning on its axis.
• The Earth takes 24 hours to complete a rotation with respect to the sun. The Earth takes a full year (365 days) for one complete revolution around the Sun
• The Earth’s axis of rotation is tilted by 23.5 degrees. This tilt causes the different seasons of the year.

• Revolution

• Revolution is the movement of the Earth around the Sun.
• The Earth takes a full year (365 days) for one complete revolution around the Sun
• The path of the Earth moving around the Sun is called an orbit. The Earth’s orbit is elliptical.

(B)

Earth's Spheres. Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
