What causes warm air to rise?
the fact that it's less dense than cold air
The fact that it weighs more than cold air
The fact that it has higher pressure than cold
the fact that its more dense than cold air
What causes wind to blow?
Differences in longitude
Shock waves from clouds
Differences in air temperature and pressure
The rotation of the earth
Which term best describes how the earth's atmosphere is heated?
Spirally
Unevenly
Circularly
Kinetically
How are the winds in the northern hemisphere different from winds in the southern hemisphere?
Winds int he northern hemisphere are deflected right; winds int eh southern hemisphere are deflected left
winds in the northern hemisphere are deflected south; winds in the southern hemisphere are deflected north
winds in the northern hemisphere are deflected eart; winds in the southern hemisphere are deflected west
winds in the northern hemisphere are deflected left; einds in the southern hemisphere are deflected right
With wind-electric turbines, electric energy is turned into rotational energy.
True
False
What is called the cooler air that rushes to fill the space left by hot air leaving when temperature rises?
Water
Wind
Current
Gas
What ruler planned to use wind power for an ambitious irrigation project in the 17th century?
Hammurabi
Julius Caesar
Cleopatra
Charlemagne
Which country is currently not a leader in wind technology?
Germany
China
Denmark
Spain
The two basic types of wind turbine are:
horizontal-axis wind turbine
vertical-axis wind turbine
blade-free wind turbine
rotor-free wind turbine
What is an advantage of vertical axis wind turbine over the horizontal axis wind turbine?
It can harness winds from every direction without the need to reposition the rotor.
The blades are closer to the ground where the wind speed is higher.
The tower is strong to handle the heavy equipment on top.
The mechanical components are high off the ground so they don't have to be serviced periodically.
Which is not an essential part of a wind turbine?
Blades
Shaft
Generator
Wires
Which offers less friction as air moves across the earth's surface?
Structures
Buildings
Forests
Oceans
What is the global potential wind power on land and near shore?
10 megawatt (MW)
72 terawatt (TW)
10 terawatt (TW)
72 megawatt (MW)
It is an advantage to place wind turbines close to each other when planing a wind farm to maximize the power available for wind machines downstream.
True
False
What are wind farms and what do they do?
It's a power plant.
A bunch of wind turbines that generates power everywhere.
A bunch of windmills that generates power everywhere
A bunch of people that blow to create wind energy
How can you measure how fast the wind is blowing?
Lick your finger and stick it in the air
Anemometer
Tachometer
Wind Gauge
True or False; Wind energy is the most expensive energy in the world
True
False
True or False: Wind energy is a renewable source of energy
True
False
It is partially both renewable and nonrenewable
According to statistics by International Renewable Energy Agency (IRENA), wind energy is the second mostly used of renewable energy globally.
True
False
Malaysia doesn't harness wind for power generation. Why do you think that is?
The technology is too expensive
Lack of interest in renewable energy
Inconsistent and erratic wind patterns
Insufficient wind speeds
