This is the type of weather that is caused by a cold front.
What are thunderstorms, heavy rains, or heavy snow followed by lower temperatures?
This describes long-term weather patterns of a specific region.
What is climate?
These are some major sources of air pollution
What are factories, power plants, cars, aerosol cans, and more.
These are the 2 types of ocean currents
What are surface currents and deep (or density) currents?
Which of these descriptions indicate a condition that would cause warm temperatures?
1.Being on top of a mountain
2. Living near the equator
3. Receiving sunlight at a low angle
Living near the equator
Look at the picture below representing two air masses meeting. Describe what is happening (which air mass is rising?)
When a cold air mass meets a warm air mass, the warm air mass will rise over the cold air mass.
This is the properties of the atmosphere at a given time and location, including temperature, air movement and precipitation.
What is weather?
This is the layer of the atmosphere where weather occurs.
What is the troposphere?
Why does an increase in salinity cause a density current to form?
Saltier water is higher in density than fresh water. This denser water then sinks to the bottom, forming a current.
What is the major source of energy for wind, air, and ocean currents?
What is thermal energy from the sun which causes uneven heating of Earth's surface.
This is the type of weather causes by a warm front.
What is days of gentle rain or snow followed by warm, clear weather.
The high temperature was 85 degrees Fahrenheit yesterday.
What is weather?
Which of the following is the only list representing NATURAL components of the atmosphere?
1. pollen, oxygen, and carbon dioxide
2. dust, oxygen, and sulfuric acids
3. pollen, argon, and smog
What is pollen, oxygen, and carbon dioxide?
Your lab group has been assigned the job of making a model to show how ocean currents circulate water around the Earth. Which variables are important to look at to correctly model ocean currents?
What are water temperature, the position of the continents, Earth's spinning, salinity, and the direction of blowing wind. (at least 3)
A major cause of surface currents that does NOT have an effect on deep ocean currents.
What are global winds?
These types of weather events happen much more often on the east coast of the US because of the Gulf Stream.
What are hurricanes?
Summers are typically very warm in the southeastern part of the United States.
What is climate?
How does the temperature change as you go higher into the atmosphere?
At first it gets colder, then warmer, colder again, and finally it gets hotter and hotter until you get to space.
This describes the effect the spinning of the Earth has on the path of air currents (making them curved into of straight).
What is the Coriolis Effect?
The processing by which deep ocean currents return nutrients to the surface.
What is upwelling?
An El Niño is caused when winds shift and push warm surface water toward the west of South America. The warm water replaces the cold water that usually rises from the deep ocean near the coast. When an El Niño occurs, what effects does it have on weather patterns?
It sets off a series of events that can influence weather around the world.
Florida is usually sunny, warm, and humid
What is climate?
This concept drives air currents (think temperature change).
What is convection?
What are at least 2 ways that density changes in the ocean? (think back to the passages your summarized).
What is-
temperature change: Cold air cools the water which makes the molecules get closer together . This make the water denser which causes it to sink and form a current
salinity change due to freezing: water freezes into ice which floats on top of the water and squeezes salt into the water. This makes the water underneath higher in salinity which makes it denser and sink.
Salinity change due to evaporation: water evaporates from the surface leaving salt behind. This makes the water left behind higher in salinity which makes the water denser and sink.
These are the differences between low and high pressure systems.
High pressure systems are more dense, cool, and dry with clear sunny skies
Low pressure systems are less dense, warm, and moist with warm rainy weather.
