Explanation:
B. Lead
C. Iron
D. Gold
Answer:
C. Iron
Explanation:
It is Iron because it is asking which resources does United States, Canada and Mexico have all together and if you look at the map the same resource they have in common is iron
sand
B.
water
C.
slate
D.
mud
The correct answer is slate.
Seismic waves travel faster in slate. They are waves of energy that move through earthquakes. The way seismic waves travel through the earth’s surface is very similar to the way other types of waves travel (water, light, sound) through the earth‘s surface.
Seismic waves are energy waves that move through the earth when earthquakes occur. The ground vibrates during earthquakes and it is the movement of seismic energy that causes the vibration.
There are two types of seismic waves and these include
The body waves are types of seismic waves that move through the Earth’s interior. That is, they travel under the ground.
Surface waves are also the type of seismic waves that travels through the Earth’s surface. This type of wave travels on the earth’s surface. Surface waves are rolling motions that contribute to most of the damages whenever earthquakes take place.
However, body waves can be classified into two, and these include
Primary waves are very fast and can moves at 7km within seconds.
Secondary waves are not as fast as primary waves and travel in different actions. Secondary waves travel at about 3.5 km per second.

The correct answer is C. How seismic waves travel
Explanation:
The Earth is composed of different layers that include the crust, the mantle, the outer core and the inner core, each of these layers and the features of them have been discovered throughout the years by topographers, and other experts mainly by studying seismic waves. This can be explained as seismic waves that occur due to earthquakes, eruptions, explosions and other phenomena, travel through the different layers of Earth and depending on which layer they are they display different features and speed which is the main information scientists used to determine the layers of Earth and other features of Earth's interior. Thus, it is how seismic waves travel the one that provides scientific data about the earth's interior.
