The Sun
What is the Sun?
The Sun is a star that provides light and heat.
Why do we see different phases?
Because of the changing angles at which the Sun points at the sunlit portion as it orbits Earth.
What's the tallest mountain on Earth?
Mount Everest
What is the Sun's surface made of?
Plasma
What exactly are the dark plains (maria)?
flat basins filled with solidified basaltic lava
How hot is the Earth's core?
7,952°F
What heats the Sun's atmosphere? (Coronal)
"Heat Bombs" they travel from the Sun into the corona. In the corona, the heat bombs explode and release their energy as heat.
Why does the Moon always show us the same face (synchronous rotation)?
Tidal locking - when a celestial body's rotation period matches its orbital period, causing it to always show the same face to the body it orbits
Does wasting household water remove it from the cycle?
No, wasting household water doesn't remove it from the global water cycle
Why does the corona emit X-rays?
Its extreme heat
Why does the Moon have active volcanism (moonquakes) and a partially molten core if it's so small and cooled down?
slow shrinking due to cooling, Earth's tidal forces, and impacts
What is the deepest point in the ocean?
11,000 meters, about 7 miles, or 36,000 feet
How do sound waves reveal the sun's internal structure?
how they travel, reflect, and change speed within the Sun
Why does the Moon have so many craters compared to Earth, and how do we date them?
because it lacks an atmosphere, water, and active geology that erodes impact.
Why does water swirl differently in drains in the Northern vs. Southern Hemisphere?
The Coriolis effect.
