Why are neap tides weaker than spring tides?
The Sun and Moon pull at right angles (perpendicular), partially canceling each other’s gravity
500
Why don’t eclipses happen every month?
The Moon’s orbit is tilted (5°) relative to Earth’s orbit
500
Why are seasons opposite in the Northern and Southern Hemispheres?
because Earth’s tilt causes one hemisphere to tilt away from the Sun while the other tilts toward it
