Question 2

B. Sediment

Answer 2

Small, solid fragments of rock and other materials that are carried and deposited by wind water or ice examples would be send mod or gravel

Question 3

C. Sedimentary rock

Answer 3

Rock formed when chemical reactions cement sediments together, hardening them

Question 4

D. Igneous rock

Answer 4

Get the forms from molten rock

Question 5

E. Metamorphic rock

Answer 5

Igneous or sedimentary rock that has been changed into a new kind of rock as a result of the great pressure and temperature

Question 6

F. Plastic rock

Answer 6

Rock that behaves something mean and liquid and a solid

Question 7

G. Earthquake

Answer 7

Vibration of the earths crust that results either from volcanic activity or rock masses Suddenlink moving from a fault

Question 8

H. Fault

Answer 8

The boundary between two sections of the app that can move relative to one another

Question 9

I.Focus

Answer 9

The point where an earthquake begins

Question 10

J. Epicenter

Answer 10

The point of the surface of the earth directly above the earth quake focus

Question 11

Scientists often separate the earth into five distinct sections name though sectionals

Answer 11

Atmosphere, hydrosphere, crust mantle and core

Question 12

Of the five sections listed in question two, which can we observe directly

Answer 12

The crossed the atmosphere and hydrosphere

Question 13

What do readings of the earth does the Moho discontinued this Kanuti separate? What about the Gutenberg does Kanuti what about the Lehmann discontinuity

Answer 13

The Moho this Kanuti is between the crust and the mantle. The Gutenberg disc in the ready is at the beginning of the court. The lemon does community is between the inner and outer core

Question 14

What is the difference between the ways that igneous rock and sediment Terry rock form

Answer 14

Igneous rocks comes from lava/ magma. Sediment Terry rocks comes from sediments

Question 15

Of the three types of flat discussed in this module, which type start out as different types of rock

Answer 15

Metamorphic rocks

Question 16

What is unique about rocks in the asthenosphere

Answer 16

The raft is plastic rock

Question 17

What is the main thing scientists observe in order to learn about make up of the earths interior

Answer 17

Seismic waves

Question 18

Which is 7 AM at the import or the outer core? Why is it solid when the other is?

Answer 18

The inner core. Because of the pressure

Question 19

Where is the magnetic field of the earth generated?

Answer 19

In the course

Question 20

What causes the magnetic field of the year

Answer 20

A flow of electricity inside the course

Question 21

Give a brief description of the two main theories that attempt to explain the earths magnetic field

Answer 21

There is the Dynamo theory which states that the motion of the elbow to her would create a magnetic field and there’s the rapid the K3 which says that the magnetic field is a result of the weather there it was created

Question 22

What is the rapid – decay theory more scientifically valid then the Dynamo Siri

Answer 22

The rabbit decay Siri correctly predicted the magnetic field of the other planets

Question 23

Why is a catastrophic event like the worldwide flood in the last time and essential part of the earths history if the rapid Becky Siri is true

Answer 23

Because it eould explain why the field reversed itself

Question 24

What are two reasons that make otherwise good scientist ignore it the more scientifically valid rapid Dash the catering

Answer 24

Because the rapid DK Siri has makes the earth young lesson 10,000 years old and it relies on a global clock cataclysmic event a.k.a. the flood

Question 25

Why would life cease to exist without the earths magnetic field

Answer 25

The magnetic field reflects cosmic rays from the sun that would otherwise kill wife

Question 26

Where are the "plate" in plate tectonics

Answer 26

The plates are broken pieces of the earths crust

Question 27

What can happen when plates collide with one another?

Answer 27

Mountains or trenches conform and order a new crust

Question 28

What is Pangaea

Answer 28

The theory that the earth had one landmass in the past and it separated into the known continents

Question 29

Why do otherwise good scientist ignore plate tectonics theory despite the evidence that it exists for it

Answer 29

Because play tectonics seems to indicate an old age for the earth even though it does not necessarily mean the earth is extremely old cataclysmic event could have induced rapid plate movement

Question 30

What causes earthquakes

Answer 30

Plates scraping together when they move

Question 31

Briefly describe the elastic rebound theory of earthquakes

Answer 31

First two plates try to move parallel teach other because they get can get caught up on the rough edges of the others plates the bend while trying to move when they eventually break free of each other rocks snap back into place causing an earthquake

Question 32

Eight says mall a just the text and earthquake that measures for on the Richter scale. Later, he did text one that measures eight. How many more times energy does the second earthquake release as compared to the first

Answer 32

The earthquake that measured four equals 32 to the fourth power So eight equals 32 to the eighit's power to 32 to the eighth power divided by 32 to the fourth power equals 32 to the fourth power which equals 1048576

Question 33

Name for times of mountains. What is required for the formation message

Answer 33

The phone like mountains require where to call plane wasn't 14 mountains required like pushing together volcanic and don't mountains require magma
