Natural Hazards and Layers of Earth

Question 1

Are all natural hazards predictable? Why or why not?

Answer 1

Not all are predictable because we may not have the right technology or understanding of the disaster.

Question 2

Giving examples of Geologic and Weather disasters

Answer 2

Geological: Landslides, earthquakes, and volcanic eruptions
Weather: Hurricanes, floods, blizzards

Question 3

Look at the map that shows natural hazards. Predict whether an area is in danger or not. How do you know?

Answer 3

You can tell whether it is in danger because of past natural hazards, AKA historical data

Question 4

What is the order of earth’s layers?

Answer 4

Earth’s crust
Mantle
Outer core
Inner core

Question 5

How does the pressure change from earth’s outermost layer to its innermost layer?

Answer 5

The farther down you go, the more the pressure increases

Question 6

Look at a model and be able to identify the layer of the earth being pointed out.

Answer 6

N/A

Question 7

What is the inner core made out of? Solid, liquid, or in between?

Answer 7

The inner core is made out of iron and nickel. It’s solid

Question 8

What is the outer core made out of?
Solid, liquid, or in between?

Answer 8

The outer core is a liquid layer of iron, nickel, sulphur, and oxygen

Question 9

What is the mantle made out of?
Solid, liquid, or in between?

Answer 9

This layer is made out of lithosphere, asthenosphere, and mesosphere. Rocks are partially melted and move slowly.

Question 10

What is earth’s crust made out of?
Solid, liquid, or in between?

Answer 10

The crust is made out of oceanic and continental crust. Oceanic crust is liquid, continental crust is solid

Question 11

What are convection currents? Draw a model

Answer 11

The natural process of heat transfer involving the movement of energy and heat from one place to another. (Search up image)

Question 12

IGNORE

Answer 12

IGNORE

Question 13

How can you predict natural hazards? (3 ways)

Answer 13

Scientific understanding, historical data, and data monitoring

Question 14

What is the difference between Geologic and Weather Disasters?

Answer 14

Geological has to do with the earth while weather disasters has to do with extreme weather.

Question 15

What is a geological disaster?

Answer 15

A geological disaster occurs when natural processes within or on the earth impact on our activities, either through death, injury, or through economic loss.

Question 16

What is a weather disaster?

Answer 16

Weather disasters cause damage by extreme weather. Ex: Rain, drought, snow, extreme heat or cold, ice, or wind.

Question 17

What is the difference between a natural hazard and a natural disaster?

Answer 17

Natural hazards may have a negative effect on the environment. Natural hazards can become natural disasters if there is widespread death, injury, property damage, or damage to an ecosystem. Natural hazards are worse.

Question 18

What is a natural hazard?

Answer 18

Events in nature that may have a negative effect on humans or the enviornment

Question 19

What is a natural disaster

Answer 19

Any natural hazard can become a natural disaster if it causes widespread injury, death, property damage, or damage to an ecosystem.

Question 20

Give an example of both a natural hazard and a natural disaster

Answer 20

Natural hazards: Asteroid falling, earthquakes, floods, tsunamis, and volcanic eruption
Natural disasters: Tornadoes, hurricanes, wildfires, droughts
