False
Question 1
1.
When you compare hurricanes to tornadoes, hurricanes are ___________
smaller, and tornadoes are less powerful
larger, but tornadoes may be more powerful
larger, and are always more violent
smaller, but tornadoes may be more violent
Question 2
2.
Unlike hurricanes, tornadoes...
<select all that apply>
form all over the world
form over tropical seas
have stronger wind speeds than hurricanes
Question 3
3.
Why do winds on the ground move slower than winds in the air
Winds in the air have bubbles
Winds have side movement near the ground
Winds on the ground experience friction, which slows them down.
Question 4
4.
How do scientists think a tornado is formed?
Earthquakes cause the winds to uplift and pull on the air in a circular path
Slow winds along the ground meet faster wetter wind in the air that are moving in the opposite direction
Question 5
5.
What scale is used to measure the strength of a tornado
The LS scale
A Seismograph
The Richter Scale
The Enhanced Fujita Scale (EF)
Question 6
6.

Next to the shore line or coastal areas.
Near plate boundaries
Near the ocean
Question 7
7.
What does a Richter scale measure?
The size of a tsunami
The intensity of an earthquake
The size of a seismic wave
The location of an earthquake

8.
Both California and Alaska are located near ____________ which is known for its seismic actvity
The Ring of FIre
The Equator
The North Pole
Question 9
9.
Why does Alaska experience stronger and more frequent erthquakes
Because California is warmer and expereicnes more climate changes because of pollution
Because Alsask is bigger than California
Because Alaska is located on the North American and Pacific plate boundaries
Because Alaska is colder
