Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How tall is Scale height?Approximately 11 kilometers (7 miles) at sea level
2. What is the related concepts?Hydrostatic equilibrium, exponential decay, atmospheric escape, stellar scale height, barometric formula
3. Why does scale height depend on temperature?In the formula H = kT/mg, temperature is in the numerator, so a hotter atmosphere has a larger scale height and spreads out more.
4. How does gravity affect scale height?Gravity is in the denominator of H = kT/mg, so stronger gravity makes the scale height smaller, meaning the atmosphere is more compressed.

Euler's Number (e): An irrational mathematical constant, approximately 2.71828, fundamental to exponential growth and decay.
Hydrostatic Equilibrium: A state where the inward force of gravity is balanced by the outward force of pressure in a fluid.
Mean Molecular Mass: The average mass of molecules in a gas mixture, crucial for determining atmospheric properties.
