Question

1. what is the role of the moon in the tides on earth? *

a. the moon has no effect on the tides.
b. the moons gravitational pull causes high and low tides.
c. the moon reflects sunlight to create tides.
d. the moon causes tidal waves.

1. how long does it take for the earth to complete one orbit around the sun? *

a. 1 day
b. 7 days
c. 28 days
d. 365 days

1. what is the earths tilt responsible for? *

a. the changing seasons
b. the formation of mountains
c. the ocean currents

Explanation:

1. For question 12: Tides are primarily driven by the gravitational attraction between celestial bodies; the Moon's gravity pulls on Earth's oceans, creating high and low tides. Tidal waves are a misnomer here (they refer to tsunamis, not regular tides), sunlight reflection has no role in tides, and the Moon clearly affects tides.
2. For question 13: Earth's orbital period around the Sun is defined as a solar year, which is approximately 365 days. 1 day is Earth's rotation period, 7 days is a week, and 28 days is roughly the Moon's orbital period around Earth.
3. For question 14: Earth's 23.5-degree tilt means different parts of the planet receive varying amounts of sunlight throughout the year, leading to changing seasons. Mountain formation is from tectonic activity, and ocean currents are driven by multiple factors like wind and density, not axial tilt.

Answer:

1. b. The Moon's gravitational pull causes high and low tides.
2. d. 365 days
3. a. The changing seasons
