Name the four basic types of weather fronts:
What are: *cold *warm *stationary and *occluded fronts
100
The name for this type of cloud comes from Latin meaning "a pile" because they are fluffy--like cotton puffs.
What is CUMULUS
100
Name 3 main factors which affect earth's weather:
What is *thermal energy *uneven distribution of energy *water vapor in the atmosphere
100
Name the 3 basic types of air masses:
What are...arctic, polar, tropical
100
This is the term to describe when both hemispheres receive 12 hours daylight, 12 hours nighttime. In the Spring, it will begin March 20 or 21; in the Autumn, the date is Sept 22 or 23.
What is (Spring or Autumnal) EQUINOX
200
In this TYPE OF FRONT, 2 air masses traveling in the SAME direction collide. They usually result in slow, steady rains. Name this front:
What is OCCLUDED. **Bonus...double jeopardy.... (Explain how these 2 air masses collide when they are travelling in the same direction.........)
200
These types of clouds are usually found in mountainous regions, and are oval-shaped.
What is LENTICULAR
200
True or False... Our distance from the sun determines the seasons.
What is False BONUS...for double money... What determines the seasons?
200
An air mass is a large body of air with relatively uniform ____________, ___________ & ________________.
What are pressure, temperature & humidity
200
Scientists use this term to describe light that comes to earth.
What is INSOLATION
300
In this type of front, cumulonimbus clouds are usually formed by the warm air rising in response to the cold air mass. Temperatures decrease, and these fronts generally carry the MOST SEVERE weather system, including thunderstorms.
What is a COLD FRONT
300
We get this cloud name from a Latin word meaning "wisp" or "curl". They generally are found at the top of the troposphere and have a feathery appearance.
What is CIRRUS
300
What causes winds? a. return strokes b. temperature differences (imbalances) c. lines of latitude and longitude d. A + B e. B + C F. A + C
What are return strokes & latitude/longitude lines (F)
300
This air mass is very cold and dry. What kind of air mass is it?
What is arctic.
300
DEFINE aphelion and perihelion...
What is aphelion (earth is farthest it will ever be from sun) perihelion (point at which earth is closest to sun)
400
In THIS TYPE of front, masses collide and neither moves. It looks like a warm front. Winds usually blow in opposite directions up and down the front, and the weather sticks around longer.
What is a STATIONARY front.
400
This type of cloud usually forms LOW in the sky, when a mass of warm air is lifting it slowly upward. We can remember it from the Latin word which means "layer".
What is STRATUS
400
Fill in the blanks with these words: HIGH LOW HOT COLD _________ air rises. As this happens, it creates a region of ___________ pressure. _____________ air sinks. As this happens, it creates a region of __________ pressure.
What is HOT, LOW COLD, HIGH
400
An air mass is dry and warm. What kind of air mass is it?
What is continental tropical.
400
The amount of insolation our earth gets from the sun is affected by our planet's axial tilt. ABOUT how many DEGREES is the earth's average tilt?
What is 23.5 degrees
500
When THIS TYPE of front moves in, warm air tends to rise above the cooler air that was in the region. This usually causes a progression of clouds which bring a slow and steady rain plus increased temperatures.
What is WARM front.
500
This cloud is made completely of tiny ice crystals because it is found at the top of the troposphere.
What is CIRRUS
500
2 answers necessary... Because of earth's axial tilt, sunlight shines more directly on WHICH hemisphere when the earth is at aphelion (farthest from sun). At this time, what SEASON is it in the northern hemisphere?
What is... Northern (at aphelion) and The season is SUMMER.
500
When one air mass encounters another, it does NOT mix with the other air mass. Instead, it collides with the other air mass and "fights" to "take over" the region. When these 2 collide, it's called a ??????
What is WEATHER FRONT
500
This causes the wind patterns to BEND in different regions of the globe. (These winds blow near the ground.)
What is the CORIOLIS EFFECT
