One night Katrina was studying the position of the stars and the Moon in the sky. She made a sketch of the position of the Moon in the sky, as shown in the figure. What is the reason for this movement of the Moon in the sky? Responses A The rotation of Earth about its axis The rotation of Earth about its axis B Earth’s orbital motion around the Sun Earth’s orbital motion around the Sun C The Moon’s orbital motion around Earth The Moon’s orbital motion around Earth D The rotation of the Moon about its axis

Answer 1

The correct response to the question regarding the movement of the Moon in the sky is:

C The Moon’s orbital motion around Earth

The apparent movement of the Moon across the sky from the perspective of an observer on Earth is primarily due to the Moon orbiting Earth. This motion causes the Moon to change its position relative to the background stars throughout the night and over the course of different phases.

Answer 2

When a planet completes a full rotation about its axis, which of these does it also cover? Responses A A dayA day B A weekA week C A yearA year D A month

Answer 3

The correct response is:

A A day

When a planet completes a full rotation about its axis, it encompasses what is referred to as a day. A full rotation defines the length of a day for that planet.

Answer 4

Stephanie notices that the Moon rises at 7 PM local time in the east, over the peach tree in her garden. Where and when can she expect to see the Moon rise the next day? Responses A At 8 P.M. in the same placeAt 8 P.M. in the same place B At 7 P.M. in the same placeAt 7 P.M. in the same place C At 6 P.M. in the opposite directionAt 6 P.M. in the opposite direction D At 7 P.M. in the opposite direction

Answer 5

The correct response is:

A At 8 P.M. in the same place

The Moon rises approximately 50 minutes later each day due to its orbit around Earth. Therefore, if the Moon rises at 7 PM one day, the next day it will rise around 8 PM in the same location in the east.
