b) Earth Rotation on its own axis
c) Earth Revolution
d) Changing Seasons
can u tell me the meanings

Answer 1

Answer:

a)The curvature is the reciprocal of the curvature angular radius in radians. A curvature of 1.0 appears as a circle of an angular radius of 57.3° corresponding to an altitude of approximately 2,640 km (1,640 mi) above Earth's surface.

Explanation:

b)Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.

c)Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.

d)Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
