Augustin observes the moon every 3 days for 15 days. He notices that over this 15-day period,the moon looks different. What accounts for the differences in the appearance of the moon over this time period?

• The speed of the moon's orbit
• The position of Augustin on Earth
• The distance between Earth and the moon
• The position of the moon in its orbit around Earth

Why is it warmer at the equator than the poles? 

• The Earth's revolution
• Equator recieves more direct sunlight
• The Earth's tilt
• Equatro is closer to the sun

What causes seasons on Earth? 

• Earth's revolution only

• Earth's rotation only

• Earth's tilt only

• Earth's revolution and tilt

Why does the moon appear to go through phases as viewed from Earth? 

• The Earth's rotation and the angle of the sunlight
• The Earth's revolution around the Sun
• The moon's rotation
• The moons revolution around Earth and angle of the sunlight
