The model shows the Moon at four different positions as it revolves around the Earth. Position A occurred on April 1, 2017. Which statement BEST describes the moon’s position in 14 days and why?

• Position A, a 1st Quarter moon, because the moon revolves around Earth about once every 28 days.

• Position B, a 3rd Quarter moon, because the moon revolves around Earth about once every 7 days.

• Position C, a full moon, because the moon revolves around Earth about once every 28 days.

• Position D, a new moon, because the moon revolves around Earth about once every 7 days.

Why do the temperatures change over the months?

• Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.

• Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.

• Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.

• Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.

The LITHOSPHERE is the rigid outer part of the earth’s crust and upper mantle, divided into tectonic plates. Collisions and separations of the plates result in landforms.

What does the prefix "litho" mean?

• stone

• soft

• ground

• life

The ASTHENOSPHERE is the upper layer of the earth's mantle, below the lithosphere, much hotter and more fluid than the lithosphere. Convection currents in the asthenosphere move tectonic plates.

What does the prefix "astheno" mean?

• stone

• soft

• ground

• life
