Question

5 this question has two parts. first answer part a. then answer part b.
(a) part a
based on the data shown in figure 2, which statement is correct?
a each planet has a unique orbit that changes in direction and speed every year.
b all planets orbit our sun in a predictable pattern in the same direction.
c the size of the sun and the size of the planets have no effect on each other which is shown by the orbits of the four rocky planets.
d the orbits of the planets are affected by the steps of the rock cycle and the formation of elements and minerals.

Explanation:

To solve this, we analyze each option:

• Option A: Planetary orbits are predictable and don't randomly change direction/speed yearly. Eliminate A.
• Option B: In the solar system, all planets orbit the Sun in a predictable (elliptical) pattern and mostly in the same direction (prograde). This aligns with astronomical knowledge.
• Option C: The Sun's gravity (related to its mass/size) affects planetary orbits. The rocky planets' orbits show gravitational influence. Eliminate C.
• Option D: The rock cycle and mineral formation are Earth - specific geologic processes, not related to planetary orbits (governed by gravity). Eliminate D.

Answer:

B. All planets orbit our sun in a predictable pattern in the same direction.
