Science:Clouds
Basic cloud types
| Question | Answer |
|---|---|
| What type of clouds have clear blue skies? | Cirrus clouds |
| Do cirrus clouds come before or after warm fronts? | Before |
| How many km are cirrus clouds? | 16km-17km |
| True or False: Cirrus clouds have bad weather | False, they have fair weather |
| What are cirrus clouds made out of? | Ice crystals |
| How many feet do stratus clouds go up to? | 6,500 feet |
| Do Stratus clouds form at low or high altitudes? | Low |
| Are these clouds low? | Yes |
| What color are stratus clouds? | Greyish |
| What does stratus clouds resemble? | Fog |
| What cloud causes light to no precipitation and cover the whole sky | Stratus Clouds |
| What is fog? | When air is cooled to its dew point near the ground |
| What cloud is fog? | Stratus |
| What are air masses? | HUGE bodies of air that forms over water or/and in tropical or polar regions |
| What determines the weather conditions of an air mass? | Temperature and humidity of the air masses as they form. Warm, cold, dry, or moist determines the weather as air masses move. |
| Describe fronts | Fronts are boundaries where air masses move and collide with each other. They are basically warm air and cold air meeting together. |
| How many types of fronts are there and what are the fronts names? | There are four fronts. 1. Warm Front 2. Cold Front 3. Stationary Front 4. Occluded Front |
| Describe a warm front | A warm air mass collides and rides over a cold air mass. |
| What type of weather does warm fronts bring? | Warm fronts may produce long periods of precipitation and warmer temperatures. |
| What does the symbol for a warm front look like? | Red semicircles in a line |
| Describe a cold front | A cold air mass collides and slides under a warm air mass |
| What type of weather does a cold front bring? | May produce thunderstorms and sometimes tornadoes and cooler temperatures. |
| Describe a stationary front | If neither a cold air mass or a warm air mass moves when they meet, it becomes a stationary front. |
| What type of weather does a stationary front bring? | Long periods of precipitation |
| Describe an occluded front | First you have a warm air mass that pushes into a cold air mass. Then, before it can move away, a cold air mass comes along after the warm air mass and sort of sandwiches the warm air mass. |
| What type of weather does occluded front bring? | Long periods of precipitation. |
| What forms high and low pressure systems? | Warm air rising on cold air sinking combined with the spinning of the Earth causes the air to spin |
| What type of weather does high pressure systems usually signal? | Fair weather |
| What direction do winds in a high pressure system circulate? | Clockwise direction |
| What type of weather comes with low pressure systems? | Rainy/stormy weather conditions. |
| What causes storms? | Storms occur when air pressure differences cause rapid air movement |
| What is a thunderstorm? | A storm with thunder, lightning, heavy rains, and strong winds. |
| What type of cloud are thunderstorms usually created in? | Large cumulonimbus clouds |
| How are thunderstorms formed? | They usually follow a cold front but can form within an air mass. |
| What is a tornado? | Rapidly whirling funnel shaped cloud that extends down from a storm cloud. |
| Describe a tornado | A tornado has very low pressure and strong winds. They can cause great damage to people and property. |
| How are tornado's formed? | Likely to form within the frontal regions with strong thunderstorms. |
| Describe a hurricane | *Low pressure tropical storm *ONLY forms over warm ocean water *Winds spin in a circular pattern around a center (eye) *The lower the air pressure at the center, the faster the winds blow toward the center of the storm |
| What measurement unit is air pressure measurement | Milliliters |
| What measurement tool is air pressure measured in? | Barometer |
| wHAT IS THE SIMPLEST KIND OF BAROMETER? | Mercury Barometer |
