Cloud and Seasons
A fluffy cloud whose name means "a pile" in Latin.
What is cumulus?
Imaginary lines that run north/south across the earth
What are lines of longitude?
A boundary between two air masses.
What is a weather front?
A wave with a direction of propagation (travel) that is perpendicular to its direction of oscillation.
What is a transverse wave?
The sound produced as the result of an object traveling at or above Mach 1.
What is a sonic boom?
The difference between cirrus clouds and stratus clouds
Name one cause of wind on earth
What is temperature differences that cause areas of high pressure and low pressure?
Rising air creates areas of _________ pressure.
What is low pressure?
An example of something that travels in a longitudinal wave.
An indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
What is pitch?
A cloud prefix that means "high" and a prefix or suffix that means "dark."
What are "alto" and "nimbus"?
The way in which the rotation of the earth bends the path of winds, sea currents, and objects that fly through different latitudes.
What is the Coriolis Effect?
Four basic types of weather fronts.
What are cold fronts, warm fronts, stationary fronts, and occluded fronts?
The distance from one point on a wave to an identical point on the next wave.
What is wavelength?
Describes the way that motion affects the pitch of a sound.
What is the Doppler Effect?
The difference between a solstice and an equinox.
What is a solstice occurs in summer and winter when the sun is furthest from the equator, making the longest or shortest days?
What is an equinox occurs in spring and autumn when the sun is directly over the equator, making equal day and night lengths?
Warm air at the Equator rises leaving an area of low pressure. The warm air (that rose) spreads out and cools in the atmosphere, then falls to earth again creating an area of high pressure. This air travels to areas of low pressure, warms, and begins the cycle again.
What is a Hadley Cell?
The type of weather front is that is the cause of most severe weather systems.
What is a cold front?
What is an ultrasonic wave?
Describe a Ruben's Tube.
What is a tube that is filled with gas and has many holes in a line. The holes are lit, and the vibrations from nearby sound is carried through the air in the tube, making the flames dance in a wave.
A definition for the aphelion and perihelion.
What is the aphelion is the farthest the earth will ever be from the sun?
What is the perihelion is the closest the earth will ever be from the sun?
Two different types of winds on earth
What are polar easterlies, westerlies, or trade winds? (name two)
At nighttime, high elevations usually cool faster than low elevations. Thus, at night, the land on a mountain is usually cooler than the land in the valley next to the mountain. Describe the direction the wind will blow: from the mountain into the valley or from the valley up to the mountain?
What is from the mountain to the valley?
The relationship between wavelength and frequency
What is they are inversely related. If one increases, the other decreases and vice versa.
The speed of sound in air that has a temperature of 20℃. Use the following equation and show all your work:
v = (331.5 + 0.6 ⋄ T) m/sec
What is 343.5 m/sec?
