Increasing the number of times Earth rotates on its axis.
Decreasing the speed of the Moon’s orbit around Earth.
Decreasing the amount of energy the Sun emits per year.
The changing appearance of the Moon during the lunar cycle is the result of the changing -

Students use the materials pictured here to create a model of the lunar cycle. The action the students must perform to demonstrate what causes the changing appearance of the Moon from Earth is -
moving the tennis ball around the flashlight.
covering up different amounts of the flashlight.
moving the tennis ball around the basketball.
moving the flashlight around the basketball.
Which lunar phase will occur approximately 7 days after a first quarter moon?
New moon
Full moon
Waxing crescent
Waning Crescent
Which of the following best describes how the interaction of the Sun, Moon and Earth result in the lunar cycle? Light from the Sun -
illuminates different amounts of the Moon’s surface as the distance between the Sun and Moon changes.
always illuminates half the Moon, but we see different portions of the lit half as relative positions change.
illuminates the entire surface of the Moon at all times, but looks different because of Earth’s shadow.
reaches only the parts of the Moon not blocked by clouds, which shrink and grow over time.
Which of the following would have the greatest effect on the size of tides on Earth?
Slowing the rate of rotation of the Moon.
Increasing the rate of revolution of Earth.
Decreasing the distance between the Moon and Earth.
Increasing the distance between the Moon and the Sun.
High tides are created on Earth when nearby celestial bodies create what change in the oceans?
Electromagnetic waves reverse the direction of ocean currents.
Water is warmed by the Sun and then rises to higher levels.
Radiation striking the water increases salt content.
Gravity pulls on the water creating bulges on two sides of Earth.
The diagram shows where in the Moon’s orbit it will create different moon phases. Spring tides are the strongest tides and neap tides are the weakest tides. Based on this information and the relative positions of Earth, the Moon and the Sun shown in the diagram, which of the following accurately identifies which moon phases are visible when spring or neap tides occur?
Spring Tides = First Quarter & Last Quarter Neap Tides = Full Moon & New Moon
Spring Tides = First Quarter & Full Moon Neap Tides = Last Quarter & New Moon
Spring Tides = Full Moon & New Moon Neap Tides = First Quarter & Last Quarter
Spring Tides = Last Quarter & New Moon Neap Tides = First Quarter & Full Moon

W and Y
X and Z
X and Y
What are the two main factors that create the tides on Earth?
Gravitational forces and rotation of Earth on its axis.
Phases of the Moon and distance from the Moon.
Distance from the Sun and distance from the Moon.
Gravitational forces and rotations of Moon on its axis.
