Name all 5 layers of the atmosphere.
Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
What type of weather happens at a cold front?
Violent storms, heavy and intense precipitation
cooler temperature
What is the difference between weather and climate?
the current state of the atmosphere- weather
The average weather of a place over a long period of time(30+ years)- climate
What is the name of the tool that measures air pressure? The tool that measures temperature?
The tool that measure wind?
1. Barometer
2. Thermometer
3. Anemometer
What layer of the atmosphere does weather occurs?
troposphere
What is the difference between a weather forecast and a weather report?
weather forecast- prediction of future weather
weather report- what the weather is like right now
Why do we have different weather in different seasons of the year?
the Earth is tilted on it's axis and revolves around the sun, causing certain parts of the Earth to receive more or less sunlight at different times of the year
tropical, dry, severe, polar, highland, mild
What are 3 factors that shape climate?
Latitude
Distance from Water
Elevation
Global Winds
Ocean Currents
Topography
approximately what percent of Earth is covered by water?
71%
define clouds
large collections of tiny liquid droplets or frozen crystals. when these droplets become too heavy for air currents to hold them up, they fall down as precipitation.
What is the formula for converting degrees Fahrenheit into degrees Celsius?
Convert 10 degrees F to C
C= 0.55 (F-32)
What are 3 consequences of climate change?
more extreme weather patterns
rising sea levels and flooding
polar ice caps melting
droughts that can affect food sources
disappearance of habitats
extinction of species
What are the two main jobs of the atmosphere?
Protection- from meteors/UV light
Trapping- of gasses needed for life and heat
what is wind?
the movement of air from one high pressure to low pressure
What are 3 processes that ensure water is cycled in Earth's system?
Evaporation-heats water from surface causing it to rise into the atmosphere
Condensation- cools water vapor and form clouds
Precipitation- water falls back to surface to be reused
what is the gulf stream?
A warm ocean current that carries warm water from the tropics toward Western Europe.
Refute the following statement "My town just had the largest snowfall on record in the past 100 years, so obviously global warming is a joke."
This person is confusing weather with climate-just because there is a spike in cold weather or snow for a few days does not mean that the annual temperatures around the globe are not rising.
list at least 3 gases that Earth's atmosphere is made up of and their percentage.
78% nitrogen
21% oxygen
Less than 1% other gases such as argon, carbon dioxide and water vapor.
define mean, median, mode and range
mean- average
median- middle number
mode- value that appears most often
range- the difference between the lowest and highest values
Give the mean, median, mode and range for the list of temperatures below:
29, 42, 15, 8
mean- 8+15+29+42=94/4=
median- 8,15,29,42= 15+29=44/2=22
mode- none
range- 42-8= 34
What is the formula for converting degrees Celsius into degrees Fahrenheit
Convert 24 degrees C into F
F= (1.8 X C) + 32
What is the greenhouse effect? How do humans contribute to the greenhouse effect?
greenhouse gases trap radiation from the sun in the atmosphere causing the Earth to warm, the burning of fossil fuels in factories or transportation by humans releases carbon dioxide which is a greenhouse gas
