Density
What is density?
How tightly packed molecules are
Solids - tightly packed, organized
Liquids - close together
Gas - Far apart
What causes surface currents?
Wind
What is the difference between weather and climate?
Weather: day to day, short term conditions of a specific area
Climate: long term average conditions of a specific area
What is light intensity?
The measurement of light directly hitting the surface of the Earth
The transfer of heat through liquids and gases. Warm will rise, cold will fall. This continues in a cycle.
Convection
Warm water is ________ dense than cold water
Less
What 2 things impact deep ocean currents?
Temperature and Salinity
This climate zone is located at the very top and bottom of the globe - located at the Arctic Circle (north) and Antarctic Circle (south). This region is very cold due to less light intensity.
Polar Zone
Where in the world gets the most intense, direct sunlight?
The equator
Does the earth spin clockwise or counterclockwise in its axis?
Counter clockwise
Cold air is ________ dense than warm air
True or false: Currents flowing from areas near the equator are cold
If false, make the statement correct
False
Currents flowing from areas near the equator are warm
This climate zone is found near the equator, between the Tropic of Cancer and the Tropic of Capricorn
Tropical Zone
Where in the world gets the least intense, direct sunlight?
Polar regions
This phenomenon is driven by differences in water temperature and salinity (density). It begins with cold, salty, dense water sinking in the North Atlantic and around Antarctica, driving a deep-sea circulation that regulates global climate and keeps European temperatures mild.
Global Ocean Conveyor Belt
Why do people float in water?
What could happen if our ocean currents changed or stopped all together?
It will affect our climate! Sea levels will rise, storms will intensify, rainy and dry seasons would flip, Earth's temperatures would be more extreme (both cold and hot depending on latitude), and more
This climate zone is warm all year round due to direct sunlight but are very dry. Where most of the world's deserts are located.
Subtropical Zone
Mid-latitude regions (sub-tropic & temperate zones)
This phenomenon causes the prevailing winds to curve or bend due to Earth's rotation
The Coriolis Effect
Explain why an egg will sink in fresh water but will float in salt water. Include density in your answer.
The egg will sink in fresh water because fresh water is less dense. It will float in salt water because salt water is more dense, not allowing the egg through.
What caused 28,000 rubber duckies to continuously move about the planet? Give a detailed explanation that includes at least 2 of the following: ocean currents, temperature, density, salinity, climate zones
Includes at least 2 of the following: ocean currents, temperature, density, salinity, climate zones
This climate zone experiences seasons, and the temperatures and climate vary depending on amount of direct or indirect sunlight. This is where we live!
Temperate Zone
Why is it hottest near the equator and coldest as we move towards the poles? Your explanations need to include light intensity.
The equator is hottest because it is in the most constant, direct sunlight throughout the year, making the light intensity high and temperatures warmer.
The poles are the coldest because they receive sunlight at an angle, making the light intensity low and temperatures colder.
Due to the Coriolis Effect, do the winds blow clockwise or counter clockwise the Northern Hemisphere?
Clockwise
