Main cause: The moon's gravity pulls on the water in the oceans.
Secondary cause: The sun's gravity makes tides more extreme (extra high + extra low) during new moon and full moon, or less extreme during 1st and 3rd quarter moon
Cause: During a new moon, the moon blocks our view of the sun
Effect: Solar eclipse
Cause: During a full moon, the Earth's shadow falls across the moon, making it turn dark (and even red!)
Effect: Lunar eclipse
Cause: Gravity pulled dust together into a spinning disc, then pulled clumps together into the sun + planets
Effect: Formation of solar system
Cause: The earth rotates on its axis
Effect: Day and night (24 hours)
Cause:The earth's axis is tilted, so as it revolves around the sun, hemispheres get different amounts of direct and indirect sunlight.
Cause: Weathering breaks down rocks into sediments and erosion carries the sediments to new places
Effect: Mountains are worn down and sediments are deposited at the bottom of lakes, rivers, and oceans
