What instrument is used to measure wind speed? An anemometer.
Which do you think will heat up more quickly on a sunny day, the water in a lake or the sand surrounding it? The sand.
What is the difference between a local and a global wind? Local winds blow over short distances and global winds blow over long distances.
Name the three major global winds? Trade winds, pervailing westerlies, and the polar easterlies.
How do clouds form? When water vapor in the air becomes liquid water.
What clouds indicate fair weather? All except Nimbus.
Do all clouds produce precipitation? No.
How does precipitation form? Condensation.
Can precipitation fall without clouds? No.
Which clouds indicate rain? Nimbus.
How do metearologists measure rainfall? Rain gauge.
In general, 1 inch of rain equals how many inches of snow? 10 inches.
What are the layers of the atmosphere? The tropisphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.
As you increase in elevation, what happens to the density of the air? It decreases.
As you increase in elevation, what happens to the amount of water vapor? It decreases.
As you increase in elevation or altitude, what happens to the air pressure? It increases.
