What causes seasons on Earth?
Earth's tilt on its axis as it revolves around the Sun.
100
What causes tides?
The gravitational pull of the Moon and the Sun.
100
What is Newton's 2nd Law?
Force = mass × acceleration (F = ma).
100
What are two factors that affect gravitational force?
Mass of the objects and distance between them.
100
What base number is the metric system based on?
10
200
What is the degree of the angle of Earth's tilt?
23.5 degrees
200
Name all 8 moon phases in order.
New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent.
200
What happens if force increases but mass stays the same?
Acceleration increases.
200
Does an astronaut weigh the same on Earth and the moon?
No
200
Convert 1.2L to mL.
1,200 mL
300
Why is it hotter near the equator?
The equator receives direct sunlight year-round.
300
What is a spring tide?
A tide with the greatest high tides and lowest low tides, occurring during new and full moons.
300
A toy car (1kg) is pushed with 10N. What is its acceleration?
10 ÷ 1 = 10 m/s².
300
Why does a truck take longer to stop than a car?
The truck has more mass, which means more momentum and requires more force to stop.
300
Convert 4kg to grams.
4,000 grams
400
What season is it in the Northern Hemisphere at position 3?
Summer in the Northern Hemisphere.
400
During which moon phase does a lunar eclipse occur?
During a full moon.
400
If mass increases but force stays the same, what happens to acceleration?
Acceleration decreases
400
Why do objects fall toward Earth?
Earth has a large mass and its gravity pulls objects toward its center.
400
What is the base unit for mass in metric?
Gram
500
What is a solstice?
When the Sun is at its greatest distance north or south of the equator, marking the longest and shortest days of the year.
500
How many high and low tides typically occur each day?
Two high tides and two low tides.
500
A cart is pushed with 20N and has a mass of 4kg. Find acceleration.
20 ÷ 4 = 5 m/s².
500
How does the Sun’s gravity keep planets in orbit?
It pulls planets toward it, while their inertia keeps them moving forward — together this causes orbital motion.
