Problem Analysis:
The task is to understand the concept of
revolution in the context of Earth's movement around the Sun and to complete sentences based on that understanding. The image provided shows Earth orbiting the Sun, which visually represents revolution.
Key Concepts:
1.
Revolution: The movement of Earth around the Sun.
2.
Rotation: The spinning of Earth on its axis (which causes day and night).
3.
Duration of Revolution: One complete revolution takes approximately 365 days, or 1 year.
4.
Effect of Revolution: Causes changing seasons due to Earth's axial tilt.
Solution Explanation:
#### Sentence 1: "The movement of the Earth around the Sun is called"
-
Correct Answer:
Revolution
-
Explanation: The term "revolution" specifically refers to the motion of Earth as it orbits the Sun. This is different from "rotation," which is the spinning of Earth on its axis.
#### Sentence 2: "One revolution takes about"
-
Correct Answer:
365 days, or 1 year
-
Explanation: Earth completes one full orbit around the Sun in approximately 365 days, which is why we have a year. The option "24 hours, or 1 day" refers to the time it takes for Earth to rotate once on its axis, not to revolve around the Sun.
#### Sentence 3: "Revolution gives us"
-
Correct Answer:
The Seasons
-
Explanation: As Earth revolves around the Sun, its axial tilt (approximately 23.5 degrees) causes different parts of the planet to receive varying amounts of sunlight throughout the year. This results in the changing of seasons. The option "Day and night" is caused by Earth's rotation, not its revolution.
Final Answers:
1. The movement of the Earth around the Sun is called
Revolution.
2. One revolution takes about
365 days, or 1 year.
3. Revolution gives us
The Seasons.
Boxed Final Answer:
\[
\boxed{
\begin{array}{l}
\text{Revolution} \\
\text{365 days, or 1 year} \\
\text{The Seasons}
\end{array}
}
\]
