Questions and Answers
• 1.

### The water cycle in ORDER is:

• A.

Precipitation, Evaporation, Condensation

• B.

Evaporation, Precipitation, Condensation

• C.

Evaporation, Evaporation, Condensation

• D.

Precipitation, Evaporation, Evaporation

Correct Answer
A. Precipitation, Evaporation, Condensation
Explanation
The correct answer is Precipitation, Evaporation, Condensation. This is the correct order of the water cycle. Precipitation occurs when water vapor in the atmosphere condenses and falls to the Earth's surface as rain, snow, sleet, or hail. Evaporation happens when heat from the sun causes water to change from a liquid to a gas and rise into the atmosphere. Condensation occurs when the water vapor in the air cools and changes back into liquid form, forming clouds.

### Which of the following is NOT an example of precipitation?

• A.

Rain

• B.

Frost

• C.

Hail

• D.

Sleet

Correct Answer
B. Frost
Explanation
Frost is not an example of precipitation because it is formed by the process of deposition, where water vapor changes directly into ice without passing through the liquid phase. Precipitation, on the other hand, refers to any form of water that falls from the atmosphere to the Earth's surface, such as rain, hail, or sleet.

### Evaporation is:

• A.

Gas to liquid

• B.

Liquid to gas

• C.

Gas to gas

• D.

Falling down from sky

Correct Answer
B. Liquid to gas
Explanation
Evaporation is the process by which a liquid changes into a gas. It occurs when the molecules of a liquid gain enough energy to escape from the surface and enter the gas phase. This process is influenced by factors such as temperature, surface area, and air movement. Evaporation is a crucial part of the water cycle, as it allows water from bodies of water, such as oceans and lakes, to enter the atmosphere as vapor and eventually form clouds.

### Two types of wind are:

• A.

Low/Hot

• B.

High/Hot

• C.

Hot/ Cold

• D.

Cold/low

• E.

High/ Cold

Correct Answer
C. Hot/ Cold
Explanation
The correct answer is "Hot/ Cold". This answer suggests that there are two types of wind: one that is hot and another that is cold. This makes sense as wind can vary in temperature depending on various factors such as the climate, location, and weather conditions. Hot wind could be associated with warm or tropical regions, while cold wind could be associated with colder climates or seasons.

Rate this question:

• 5.

### Condensation is:

• A.

Gas back to liquid

• B.

Liquid to gas

• C.

Falling from sky

• D.

Gas to gas

Correct Answer
A. Gas back to liquid
Explanation
Condensation refers to the process of a gas transforming into a liquid state. This occurs when the temperature of the gas decreases, causing the gas molecules to slow down and come closer together. As a result, the gas molecules lose energy and form bonds with each other, forming a liquid. This process is commonly observed when warm air cools down, leading to the formation of water droplets on surfaces or in the atmosphere, such as clouds or dew. Therefore, the correct answer is "gas back to liquid."

Rate this question:

• 6.

### The center of a Severe Storm is:

• A.

The center

• B.

The eye

• C.

The mouth

• D.

The vortex

Correct Answer
B. The eye
Explanation
The correct answer is "the eye." In severe storms, such as hurricanes or tornadoes, the center is referred to as the eye. The eye is a region of calm weather located at the center of the storm. It is typically characterized by clear skies, light winds, and a decrease in precipitation. Surrounding the eye is the vortex, which is the area of intense rotation and strongest winds in the storm. Therefore, the eye is the correct term for the center of a severe storm.

Rate this question:

• 7.

### Hurricanes have a wind speed minimum of:

• A.

71 mpH

• B.

72 mpH

• C.

73 mpH

• D.

74 mpH

• E.

75 mpH

Correct Answer
D. 74 mpH
Explanation
Hurricanes have a wind speed minimum of 74 mph. This is because hurricanes are classified as tropical cyclones and are characterized by strong winds that exceed 74 mph. These powerful winds are a result of the intense low-pressure system that forms in the center of the storm. Wind speeds in hurricanes can reach well over 100 mph and can cause significant damage to infrastructure and pose a threat to human lives.

Rate this question:

• 8.

### The correct stages of Severe Weather (in order of first to last) is:

• A.

Hurricane, Tropical Depression, Tropical Storm

• B.

Tropical Depression, Tropical Storm, Hurricane

• C.

Tropical Storm, Depression, Hurricane

• D.

Tropical Depression, Hurricane, Tropical Storm

Correct Answer
B. Tropical Depression, Tropical Storm, Hurricane
Explanation
The correct stages of severe weather, in order from first to last, are tropical depression, tropical storm, and hurricane. This progression makes sense as a tropical depression is the initial stage where a low-pressure system forms and winds start to circulate. As the system gains strength and wind speeds increase, it becomes a tropical storm. Finally, when the wind speeds reach 74 mph or higher, it is classified as a hurricane. This sequence follows the logical progression of a weather system intensifying and reaching its peak intensity as a hurricane.

Rate this question:

• 9.

### Two things are needed to create severe tropical weather:

• A.

Wind, Waves

• B.

Wind, Whirlpools

• C.

Waves, Birds

• D.

Some W words that I don't remember ....

Correct Answer
A. Wind, Waves
Explanation
Severe tropical weather is created by the combination of wind and waves. Wind provides the driving force that initiates and sustains the weather system, while waves are a result of the wind's interaction with the ocean surface. Together, these elements contribute to the formation of intense storms such as hurricanes or typhoons.

### A line with a spike on it is a sign of:

• A.

Warm front

• B.

Cold Front

• C.

High Pressure

• D.

Low Pressure

Correct Answer
B. Cold Front
Explanation
A line with a spike on it is a sign of a cold front. Cold fronts occur when a mass of cold air moves into an area, displacing warmer air. The spike on the line represents the steep slope of the cold front, indicating a rapid change in temperature and weather conditions. This can bring about stormy weather, including thunderstorms, heavy rain, and strong winds.

### A line with a semi-circle over it is a symbol of:

• A.

Warm Front

• B.

Cold Front

• C.

High Pressure

• D.

Low Pressure

Correct Answer
A. Warm Front
Explanation
A line with a semi-circle over it is a symbol of a warm front. In weather maps, warm fronts are represented by a line with semicircles pointing towards the colder air mass. A warm front occurs when warm air moves into an area previously occupied by cooler air. As the warm air rises over the cooler air, it creates a gradual lifting of the warm air, resulting in the formation of clouds and precipitation. This symbol is used to indicate the boundary between the warm and cold air masses associated with a warm front.

### On a weather map, an L means:

• A.

High Pressure

• B.

Lawn Pressure

• C.

Low Pressure

• D.

Light Pressure

Correct Answer
C. Low Pressure
Explanation
An "L" on a weather map represents low pressure. Low-pressure systems are associated with unstable weather conditions, such as clouds, precipitation, and potentially stormy weather. In these areas, air is rising and creating a region of lower atmospheric pressure compared to the surrounding areas. This leads to the formation of clouds and the potential for rain or other forms of precipitation.

### On a weather map, an H stands for:

• A.

Hot Air

• B.

Hard Pressure

• C.

Hot Pressure

• D.

High Pressure

Correct Answer
D. High Pressure
Explanation
On a weather map, an H stands for high pressure. High pressure systems are associated with clear skies, calm weather, and sinking air. The air in a high-pressure system is denser and cooler, causing it to sink towards the ground. This sinking air inhibits cloud formation and leads to stable atmospheric conditions. High-pressure systems are typically associated with fair weather and are often responsible for clear and sunny days.

### When there is no rain for a while, it is a:

• A.

Flood

• B.

Drought

• C.

Tornado

• D.

Hurricane

Correct Answer
B. Drought
Explanation
A drought is a period of abnormally dry weather, typically resulting in a shortage of water. When there is no rain for a while, it can lead to a lack of water in rivers, lakes, and reservoirs, causing agricultural and ecological problems. This can result in crop failure, water scarcity, and even famine in severe cases. A drought is different from a flood, tornado, or hurricane, which are all weather phenomena involving excessive water or strong winds.

### These form on warm water:

• A.

Flood

• B.

Drought

• C.

Tornado

• D.

Hurricane

Correct Answer
D. Hurricane
Explanation
Hurricanes are formed over warm water. Warm ocean waters provide the necessary energy and moisture for the formation and intensification of hurricanes. As the warm water evaporates, it rises and condenses, forming clouds and releasing heat. This heat transfer powers the storm, causing it to rotate and grow in strength. Therefore, hurricanes are a result of the interaction between warm water and atmospheric conditions, making them distinct from floods, droughts, and tornadoes.

### There are _________  steps of the water cycle.

• A.

Two

• B.

Three

• C.

Four

• D.

Five

Correct Answer
B. Three
Explanation
The water cycle consists of three main steps: evaporation, condensation, and precipitation. During evaporation, water from bodies of water, such as lakes and oceans, turns into water vapor due to the heat from the sun. This water vapor then rises into the atmosphere. As the water vapor cools down, it condenses into clouds. Eventually, the condensed water droplets become heavy enough to fall back to the Earth's surface as precipitation, which can include rain, snow, or hail. These three steps are essential in maintaining the continuous movement and distribution of water on Earth.
