A parcel is lifted in an unstable atmosphere. Which response is most likely?

A
It is cooler and denser than the surrounding air, so it tends to sink.
B
It is warmer and less dense than the surrounding air, so it continues rising.
C
It immediately becomes saturated and stops moving vertically.
D
It remains at its new level because vertical motion is suppressed.

True
B
False

Which ingredients are typically required for thunderstorm development? Select all that apply.

A
Moisture to supply water for clouds and precipitation
B
Instability that allows buoyant air to keep rising
C
A lifting mechanism that starts the ascent
D
A temperature inversion that cannot be overcome

What happens when cloud particles become too large for the updrafts to keep them aloft?

A
They remain suspended because cloud particles cannot fall.
B
They evaporate immediately upon growing.
C
They fall as rain, snow, or another form of precipitation.
D
They turn into an updraft.

A storm has a continuing updraft, falling precipitation, and downdrafts developing alongside the updraft. Which stage is it most likely in?

A
Developing stage
B
Mature stage
C
Dissipating stage
D
Lifting condensation stage

Explain how outflow from a dissipating thunderstorm can weaken that storm yet contribute to new cloud or storm development nearby.

1 point

A parcel of air is lifted and then becomes cooler and denser than the air around it. What is the most likely response in a stable atmosphere?

A
It continues rising because it is warmer and less dense than the surrounding air.
B
It tends to sink back because it is cooler and denser than the surrounding air.
C
It remains saturated because lifting prevents its temperature from changing.
D
It forms a cumulonimbus cloud because all stable air produces strong updrafts.

Choose one

1 point

Wind pushes air up the side of a mountain, where the air expands and cools. Which lifting mechanism is responsible?

A
Convergence, because winds bring air together near the surface.
B
Frontal lifting, because dense cold air pushes beneath warmer air.
C
Orographic lifting, because terrain forces wind-driven air upward.
D
Surface heating, because the Sun warms the ground unevenly.

Choose one

1 point

Warm, moist air is present near the ground, but a layer warms with height and limits upward motion. What effect can this layer have?

A
The inversion can act as a cap that limits rising air and delays cloud growth.
B
The inversion guarantees that surface air will immediately become saturated.
C
The inversion causes all rising parcels to release latent heat before reaching saturation.
D
The inversion makes the air above it denser, so precipitation must begin.

Choose one

1 point

A rising parcel reaches saturation and condensation begins. How does this affect the parcel's cooling compared with its unsaturated ascent?

A
The parcel stops cooling because saturation prevents further expansion.
B
The parcel cools faster because condensation removes heat from it.
C
The parcel warms at the dry adiabatic rate because cloud droplets absorb sunlight.
D
The parcel cools at a lower, variable rate because condensation releases latent heat.

Written response

1 point

An unsaturated parcel rises, expands, and cools until it becomes saturated and cloud droplets can begin to form. What is the full name of this level?

Written response

1 point

An unsaturated parcel rises 2 kilometers. Using the approximate dry adiabatic lapse rate of 9.8°C per kilometer, what is its approximate temperature decrease?

True or false

1 point

True or false: Outflow from a thunderstorm can lift nearby warm, moist air and help new clouds or storms form along the resulting boundary.

A
True
B
False
