6.1 Earth's Dynamic Interior Review

Information gained by observing an actual event or phenomenon is​ (a)   evidence.

Information gained by using inferences, interpretation, and logical reasoning to reach a conclusion is​ (b)   evidence.

• direct
• indirect

Put the evidence for Earth's interior into the correct category for the type of evidence it would be:

Groups:

(a) Direct Evidence

,

(b) Indirect Evidence

• Laboratory experiments showing how extreme temperature and pressure can affect rock

• Earth having a magnetic field which surrounds it

• Calculating the overall average density of Earth to be higher than that of surface rock.

• Xenoliths (from the mantle) in rocks from volcanoes

• Presence of 4.6 billion year old iron rich meteorites in the solar system

• Analyzing the behavior of seismic waves at different places on Earth's surface

What evidence gives the most information about what the interior of the Earth may be like?

• Changes in Earth's gravity from one location to another around the Earth

• The presence of a magnetic field around the Earth

• Composition of volcanic rocks found on the surface

• Information from the speed and behavior of seismic waves

Energy which is usually released from earthquakes, what type of energy travels through the Earth?

• Seismic waves
• Thermal Waves

• Electromagnetic Waves

• Acoustic Waves

Place each statement into the correct category of seismic wave:

Groups:

(a) P (primary) Waves

,

(b) S (secondary) Waves

• Travels through ONLY solid layers of Earth, and not liquid layers

• 
• 
• Fast moving

• Slower moving

• Travels through both solid and liquid layers of Earth

How do the properties of seismic waves change as they travel through the Earth?

• Seismic waves will only change speed when they go through different layers.

• Seismic waves will change speed and direction when they go through different layers.

• Seismic waves will only change direction with they go through different layers.

• Seismic waves do not change their properties as they go through different layers.

What would a seismic station detect at each location around the Earth?

• Seismic Station A

• Does not detect either P or S waves

• Seismic Station B

• Detects only P waves

• Seismic Station D

• Detects both P and S waves far apart from each other

• Seismic Station C

• Detects both P and S waves close to each other

Shortly after the Earth had formed,​ (a)   created the individual layers by gravitationally pulling the​ (b)   dense material to the middle of the Earth.

• differentiation
• accretion
• most
• least

The​ (a)   layers of Earth are divided according to what elements and other substances they are made of.

The​ (b)   layers of Earth are divided according to their physical characteristics or how they behave.

• compositional
• structural
