Write one wondering question you have about this picture.

1

What direction does air move in high pressure systems?

From low pressure areas to high pressure areas

From high pressure areas to low pressure areas

Remain stationary

Randomly changing directions

1

What type of weather is commonly associated with high pressure systems?

Heavy rainfall

Snowy conditions

Stormy weather

Clear, calm weather

1

Why do winds blow from high to low pressure regions?

Due to gravity

Due to Earth's rotation

To balance out the pressure differences

Because of thermal heating

Required

1

What is the Coriolis effect?

A gravitational pull by the moon

Essence of Earth's magnetic field

An effect that causes moving objects to follow a curved path due to the Earth's rotation

The movement of air due to temperature differences

Required

1

Why wind doesn't move in a straight line due to the Coriolis effect?

Because of the rotation of the Earth

Because of the high pressure of the wind

Because of the presence of mountains and buildings

Due to the unequal heating of the Earth

Required

1

How does the Coriolis effect influence weather pattern?

It changes the Earth's temperature

It directly causes thunderstorms

It helps in the rotation of storm systems

It increases rainfall in the tropics

Summarize the big ideas about High and Low pressure in your notebook!

1

If the barometric pressure is rising, will do you think the weather will become more or less cloudy?

More

Less

1

Tre notices the barometric pressure is falling when he fills out his weather log. His friend in the afternoon saw the same thing. In fact, the pressure has been dropping all day. Describe what will most likely happen with the weather later tonight or tomorrow.
