- A student has a rectangular block. It is 2 cm wide, 3 cm tall, and 25 cm long. It has a mass of 600 g.
- First, calculate the volume of the block:
Then, use that answer to determine the density of the block:
volume = 150 cm3 , density = 4.0 g/cm3

The diagram below shows the locations of several volcanic mountains on the big island of Hawaii.
Which two volcanic mountain summits are closest to 50 kilometers apart?
Kilauea and Mauna Kea

Earth’s rotation spins Earth’s liquid metal outer core around its solid metal inner core. How does this phenomenon make life on Earth possible?
It creates the magnetosphere, which diverts high-energy particles from space away from Earth’s surface.

Every day, the Moon rises a little more than a half an hour later than it rose the day before. Which statement BEST explains this phenomenon?
One Earth rotation is faster than one Moon revolution around Earth.

A topographic map of part of Arizona is shown below.
Which of the labeled points on the map has the steepest slope?
3
300
How does the latitude of a region affect its climate?
by determining the angle of sunlight throughout the year
300
Earth’s magnetosphere is not uniformly shaped. It is compressed on the side facing the Sun and has a long tail extending away from the Sun. Which phenomenon is responsible for this shape?
solar winds bringing high-energy particles toward Earth

The diagram shows the difference in sunlight reaching Earth at Points 1 and 2.
Based on the diagram, what is another difference between Points 1 and 2?
The region at Point 1 is experiencing summer while the region at Point 2 is experiencing winter.
400
Which best describes how energy from the sun helps to maintain life on Earth?
It heats Earth’s atmosphere and surface, which helps stabilize temperatures on Earth and creates environments more favorable for life to exist.
400
The temperate zones of the United States experience changing of seasons from winter to summer. Which is the reason for this annual change of seasons?
the tilt of Earth’s axis of rotation

A direct alignment of bodies in the solar system can occur.
This alignment causes which phenomenon at Point X on Earth?
solar eclipse
