Chapter 1 Quiz: Weather Patterns

1. What is evaporation?

• the process by which a liquid changes into a gas

• water as a gas

• the process by which a gas changes into a liquid

• conditions such as rain, clouds, and wind at a particular time and place

Answer explanation

Evaporation is defined as the process by which a liquid changes into a gas. This occurs when molecules in a liquid gain enough energy to enter the gaseous state, making this choice the correct answer.

2. What is water vapor?

• water as a gas

• the process by which a gas changes into a liquid

• conditions such as rain, clouds, and wind at a particular time and place

• the layer of the atmosphere closest to Earth, where weather happens

Answer explanation

Water vapor is defined as water in its gaseous state. It is an essential part of the water cycle and contributes to weather phenomena, but the correct choice specifically describes it as 'water as a gas'.

3. Which air parcel will have more rainfall?

• Both would have the same amount of rain.

• Air Parcel 1 because it will lose energy and there is a greater difference in temperature.

• Air Parcel 2 because it is colder inside the parcel.

Answer explanation

Air Parcel 1 will have more rainfall because it loses energy as it rises, leading to condensation. The greater temperature difference enhances this process, resulting in more precipitation compared to Air Parcel 2.

4. Mrs. Richards left a cup of hot coffee in her classroom. When she returned, she noticed that the coffee was a lot cooler. How cold could the coffee have got?

• Colder than her classroom. It will cool down every minute until it gets to 0 degrees.

• Only as cold as the temperature of the room. It will stop cooling down when it EQUALS the same temperature as the room.

• There is no way to tell what will happen.

• It would remain the same temperature no matter what.

Answer explanation

The coffee will cool down until it reaches the same temperature as the room. It cannot get colder than the room temperature, as heat transfer stops when both are equal.

5. What is condensation?

• the process by which a gas changes into a liquid

• water as a gas

• the process by which a liquid changes into a gas

• conditions such as rain, clouds, and wind at a particular time and place

Answer explanation

Condensation is the process by which a gas changes into a liquid. This occurs when gas molecules lose energy and come together to form liquid, such as when water vapor turns into liquid water.

6. What is an air parcel?

• an amount of air that moves as a unit

• water as a gas

• the process by which a liquid changes into a gas

• conditions such as rain, clouds, and wind at a particular time and place

Answer explanation

An air parcel is defined as an amount of air that moves as a unit. This concept is crucial in meteorology for understanding weather patterns and atmospheric behavior.

7. One morning Alisha woke up and opened her curtains and couldn’t see out of her window. Her window was covered with liquid water droplets like in the image below. She wanted to know why this happened. How could you explain this to her?

• The water vapor in the air in her house CONDENSED and became liquid water drops on her window.

• The water vapor in the air in her house EVAPORATED and became liquid water drops on her window.

• The water vapor in the air in her house PRECIPTATED and became liquid water drops on her window.

Answer explanation

The water vapor in Alisha's house cooled down when it came into contact with the cold window, causing it to CONDENSE into liquid water droplets, which is why she couldn't see out.

8. Who became the first woman to earn a PhD in meteorology?

• Joanne Simpson

• Miley Cyrus

• Mrs. Richards

• Henrietta Leavitt

Answer explanation

Joanne Simpson became the first woman to earn a PhD in meteorology in 1949, making significant contributions to the field and paving the way for future female scientists.

9. What happens when water vapor cools? Choose all that apply. (Hint there are three answers.)

• It becomes liquid water.

• It stays the same.

• Energy transfers

• Clouds form.

Answer explanation

When water vapor cools, it condenses into liquid water, releasing energy in the process. This energy transfer can lead to the formation of clouds as the vapor condenses around particles in the atmosphere.

10. The energy that transfers out of an air parcel to form clouds originally comes from:

• people

• sun

• electricity

• coal and oil

Answer explanation

The energy that transfers out of an air parcel to form clouds originally comes from the sun. Solar energy heats the Earth's surface, causing evaporation and ultimately cloud formation.
