Answer:

 \huge\bold{\purple{\fbox {\pink{\mathbb{ANSWER}}}}}

  1. Earth's Axis An axis is an invisible line around which an object rotates, or spins. The points where an axis intersects with an object's surface are the object's North and South Poles. In this illustration, Earth's axis is represented by the red line.
  2. Plane of Ecliptic The ecliptic is the plane of Earth's orbit around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars.
  3. Perihelion Apsis denotes either of the two extreme points in the orbit of a planetary body about its primary body. The plural term, "apsides," usually implies both apsis points; apsides can also refer to the distance of the extreme range of an object orbiting a host body.
  4. Aphelion The point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
  5. Ferrell's law A law stating that Coriolis forces deflect winds and freely moving objects to the right in the northern hemisphere and to the left in the southern hemisphere.
  6. Rotation A rotation is a circular movement of an object around a center of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin.

earth's axis-

An axis is an invisible line around which an object rotates, or spins. The points where an axis intersects with an object's surface are the object's North and South Poles. In this illustration, Earth's axis is represented by the red line. The white circle represents axial precession, the slow "wobble" of the axis.

perihelion-

The perihelion is the point in the orbit of a planet, asteroid or comet that is nearest to the sun. It is the opposite of aphelion, which is the point farthest from the sun.answer :

aphelion-

The aphelion is the point in the orbit of an object where it is farthest from the Sun. The point in orbit where an object is nearest to the sun is called the perihelion. The word aphelion derives from the Greek words, apo meaning away, off, apart and Helios.

rotation-

A rotation is a transformation that turns a figure about a fixed point called the center of rotation. • An object and its rotation are the same shape and size, but the figures may be turned in different directions. • Rotations may be clockwise or counterclockwise.

plane of ecliptic-

The ecliptic is the plane of Earth's orbit around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars.

perihelion-

the law that wind is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, derived from the application of the Coriolis effect to air masses.

plz plz plz mark me as brainliest for my hard work

hope it will help u :-)
