1. The spinning of Earth around its axis is called _________.
✔ Answer: rotation
Explanation:
The Earth spins on its axis once every 24 hours. This spinning motion is called
rotation, and it causes day and night.
---
2. A real or imaginary line that an object spin around is _________.
✔ Answer: axis
Explanation:
The
axis is an imaginary line that runs through the center of the Earth from the North Pole to the South Pole. The Earth rotates around this axis.
---
3. What causes Earth’s cycle of day and night?
✔ Answer: rotation
Explanation:
As the Earth
rotates on its axis, different parts of the planet face the Sun (day) or are turned away from it (night). This rotation creates the daily cycle of day and night.
---
4. What causes seasons?
✔ Answer: revolution
Explanation:
Seasons are caused by the Earth's
revolution (or orbit) around the Sun, combined with the tilt of its axis. As Earth revolves around the Sun over 365¼ days, different parts of the Earth receive varying amounts of sunlight, leading to seasonal changes.
---
5. When does the Sun rise highest in the Northern hemisphere?
✔ Answer: June
Explanation:
In
June, during the
summer solstice (around June 21), the Sun reaches its highest point in the sky in the Northern Hemisphere. This is when the Northern Hemisphere is tilted most toward the Sun.
---
6. Which process takes Earth 365 ¼ days to complete?
✔ Answer: revolution
Explanation:
Earth's
revolution around the Sun takes approximately
365¼ days (one year). This is why we have a leap year every four years to account for the extra quarter day.
---
7. The sun is highest in the sky. Daytime is the longest. Which season am I?
✔ Answer: summer
Explanation:
When the Sun is highest in the sky and daylight lasts the longest, it is
summer in the respective hemisphere. In the Northern Hemisphere, this occurs in
June.
---
8. Which process takes Earth 24 hours to complete?
✔ Answer: rotation
Explanation:
The Earth completes one full
rotation on its axis in about
24 hours, which defines a day.
---
9. Your shadow is short when you go outside. What time of day is it?
✔ Answer: noon
Explanation:
At
noon, the Sun is directly overhead (or near its highest point), so shadows are shortest. As the Sun moves lower in the sky during morning and evening, shadows become longer.
---
10. Which season the sun shines directly on the equator on the 21 March?
✔ Answer: spring
Explanation:
On
March 21, the
Sun shines directly on the equator during the
vernal (spring) equinox. This marks the beginning of
spring in the Northern Hemisphere and
autumn in the Southern Hemisphere.
