Meg: Use a sun tanning or UV tanning booth instead of staying on the beach for long hours
Sandy: Stop all outdoor activity and always stay indoors
Chang: Apply sunscreen half an hour before going out and reapply every 2 hours
Nathan: Use sunscreen with very low SPF once per day

Question 2
Which of these statements about heating up water on Earth's surface is true?
Water heats up faster than land.
Water heats up by convection from Earth.
Water heats up by conduction from the sun.
Water heats up to a lower temperature than land.
Question 3
What happens when warm air rises?
Global temperature decreases.
The movement creates a difference in air pressure.
Cool air rises with it.
It moves towards the poles.
Question 4
Which of these can be determined based on the knowledge about weather?
If you should carry an umbrella
Plants that can be grown
Animals that may be found
Clothes that should be bought
Question 5
The image below shows a certain type of global wind:
The Earth is shown as a circle. Equator is shown and labeled at 0 degrees. 30 degrees north and south latitudes are shown and labeled. 60 degrees north and south latitudes are shown and labeled. Curved arrows are shown from the top and bottom ends of the circle towards 60 degrees north and south latitudes.
What best describes these winds?
Trade winds blowing in a curved manner due to the rotation of Earth
Polar easterlies blowing in a curved manner due to Coriolis Effect
Polar westerlies that curve due to air above poles being relatively cooler
Jet streams that curve due to air above equator being relatively warmer
Question 6
What is the most likely effect of an increase in precipitation?
Lakes dry up
Shortage of water
Decrease in humidity
Fall in air temperature
Question 7
The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
La Niña, because the jet stream is displaced southwards
La Niña, because the jet stream is displaced northwards
El Niño, because of increased upwelling of cooler waters
El Niño, because of decreased upwelling of cooler waters
Question 8Which of these is an example of weather at a place?
Continental
Polar
Stormy
Tropical
Question 9
Which of the following spheres contains the ionosphere and reflects radio waves back to Earth?
Exosphere
Stratosphere
Thermosphere
Troposphere
Question 10
Location X and Y are adjacent. Location X has a lower air pressure than Location Y. What will most likely happen?
Wind will blow from one location to another.
Air above Location Y will rise up and condense.
Temperature at the two locations will become equal.
Convection currents of air above the two locations will stop.
Question 11
At what time should we definitely seek shade to avoid sun exposure?
Between 6 a.m. and 8 a.m.
Between 8 a.m. and 10 a.m.
Between 10 a.m. and 4 p.m.
Between 4 p.m. and 10 p.m.
Question 12
Study the following ocean currents map.
An ocean currents map is shown. On the map the locations for San Diego, California and Savannah, Georgia are marked. There is a looping current from the north past San Diego and a looping current from the south near Savannah
Which statement is most likely correct about the average temperatures in San Diego, California as compared to Savannah, Georgia?
It is higher in Savannah because of the cool ocean currents from the south.
It is higher in Savannah because of the warm ocean currents from the north.
It is lower in San Diego because of the warm ocean currents from the south.
It is lower in San Diego because of the cool ocean currents from the north.
Question 13
Maria described two layers of Earth's atmosphere.
Layer A: Weather changes take place here
Layer B: Location where weather balloons collect data
Which statement is most likely true?
Layer A is the thermosphere and Layer B is the exosphere.
Layer A is the exosphere and Layer B is the thermosphere.
Layer A is the stratosphere and Layer B is the troposphere.
Layer A is the troposphere and Layer B is the stratosphere.
Question 14
What preparation should be made for a hurricane that is likely to move onshore?
Move to a high tide zone near the sea
Move to a friend's place in a low lying area
Know the nearest evacuation shelter for the zone
Turn off the radio to avoid listening to uncertain news
