How long does it take for Earth to complete one rotation?
It takes 24 hours for Earth to complete one rotation.
How does the Moon affect tides?
The Moon’s gravitational pull causes high and low tides on Earth.
What is gravity?
Gravity is the force that pulls objects toward each other, keeping celestial bodies in orbit.
Why does Earth have seasons?
Seasons are caused by the tilt of Earth’s axis as it orbits the Sun.
What is the difference between a planet and a moon?
A planet orbits a star, while a moon orbits a planet.
What causes day and night?
Earth’s rotation on its axis.
How long does it take for the Moon to orbit Earth?
About 28 days.
What is the Midnight Sun?
The Midnight Sun is when the Sun remains visible for 24 hours in polar regions during summer.
Why do we have leap years?
Leap years account for the extra 0.25 days in Earth’s revolution, adding an extra day every four years.
What is the difference between a solar and lunar eclipse?
A solar eclipse occurs when the Moon blocks the Sun, while a lunar eclipse occurs when Earth’s shadow falls on the Moon.
What is the role of Earth’s atmosphere in protecting life?
Earth’s atmosphere blocks harmful solar radiation, traps heat, and provides oxygen for life.
How does Earth’s gravity affect the Moon?
Earth’s gravity keeps the Moon in orbit around Earth.
What is Earth’s revolution?
Earth’s revolution is its orbit or path around the Sun.
What is the main reason summer is warmer than winter?
Summer is warmer because the Sun’s rays hit the Earth at a more direct angle during this time of year.
Why do we see different stars at different times of the year?
As Earth orbits the Sun, its position changes, revealing different parts of the night sky.
Why does the equator have consistent temperatures year-round?
The equator receives direct sunlight throughout the year, resulting in consistent warm temperatures.
How long does it take for Earth to complete one revolution around the Sun?
It takes about 365.25 days for Earth to complete one revolution.
What happens during a solstice?
A solstice is when the Sun reaches its highest or lowest point in the sky, creating the longest or shortest day of the year.
On what dates does the summer solstices typically occur?
The Summer Solstice usually occurs around June 21.
Why do the Northern and Southern Hemispheres have opposite seasons?
Opposite seasons occur because one hemisphere always tilts toward the Sun while the other tilts away.
What are auroras?
Auroras are colorful lights in the sky caused by solar particles interacting with Earth’s atmosphere near the poles.
What is an equinox?
An equinox is when day and night are almost equal in length.
What is the significance of moon phases in Indigenous cultures?
Indigenous cultures traditionally use moon phases to guide land-based activities like planting, harvesting, and ceremonies.
What causes the phases of the Moon?
Moon phases are caused by the changing angles of sunlight reflecting off the Moon as it orbits Earth.
When does the Spring Equinox typically occur?
The Spring (Vernal) Equinox usually occurs around March 21.
