#13. where should you go to minimize risk of lightning strike, and why?
comparing lightning strikes
coulombs law is given by (f = k\frac{q_1q_2}{r^2})
which best explains why cloud - to - ground strikes are more intense?
gravity pulls electrons downward, making the strike stronger.
charges are closer together, so the force is stronger.
charges are farther apart, so the force is weaker.
trees attract lightning because of chlorophyll.

#14. answer this question and the following multiple - choice scaffolded questions to build your understanding. then, use your answers as evidence to write a full response to the big question. where should you go to minimize risk of lightning strike, and why?
comparing lightning strikes
which strike type is more dangerous to humans and why?
cloud - to - air because it produces more light
cloud - to - air because it travels through open space
both are equally dangerous regardless of location
cloud - to - ground because it delivers more energy directly to earths surface.

Explanation:

1. For the question about why cloud - to - ground strikes are more intense: According to Coulomb's Law $F = k\frac{q_1q_2}{r^2}$, when charges are closer together (in cloud - to - ground strikes, the charges in the cloud and on the ground are relatively close compared to some other scenarios), the force is stronger. This makes the strike more intense.
2. For the question about which strike type is more dangerous to humans: Cloud - to - ground strikes are more dangerous because they deliver more energy directly to Earth's surface where humans are located.

Answer:

1. Charges are closer together, so the force is stronger.
2. Cloud - to - Ground because it delivers more energy directly to Earth's surface.
