The regular cycle of day and night.
400
What process inside the Sun produces its energy, and approximately how much energy does the Sun generate every second (in megawatts)?
Nuclear Fusion and approximately 386 billion billion megawatts, 3,86 x 10²6
400
Why do scientists think the Moon was created from material that came from Earth?
Because Moon rocks and Earth rocks have very similar compositions.
400
What layer of Earth do humans live on?
The crust.
500
Put these layers in order from the center outward: Core, Corona, Radiative Zone, Photosphere, Convection Zone, Chromosphere.
Core → Radiative Zone → Convection Zone → Photosphere → Chromosphere → Corona.
500
Why does the Moon affect ocean tides even though it is much smaller than Earth?
Because its gravitational pull attracts Earth's oceans, causing high and low tides.
500
Why would ocean tides be much weaker if Earth had no Moon?
Because the Moon's gravity pulls on Earth's oceans, creating tides.
