Day 16 Meteorology

What is atmospheric pressure?

• The weight of the air above a given point
• The temperature of the atmosphere
• The density of the atmosphere
• The movement of air from high to low pressure

What causes wind to form?

• Rotation of the Earth
• Differences in atmospheric pressure
• Ocean currents
• The Coriolis effect

Which factor primarily determines wind direction?

• Temperature differences
• Coriolis effect
• Earth's magnetic field
• Elevation

What happens to wind speed when isobars are closer together on a weather chart?

• Wind speed increases
• Wind speed decreases
• Wind direction reverses
• Wind stops entirely

In the Northern Hemisphere, how do winds circulate around a low-pressure system?

• Clockwise and outward
• Clockwise and inward
• Counterclockwise and inward
• Counterclockwise and outward

What is the Coriolis effect?

• The force that pulls winds toward the Earth's surface
• The deflection of moving objects due to Earth's rotation
• The increase in wind speed at higher altitudes
• The mixing of warm and cold air masses

What are trade winds?

• Winds that blow from east to west in the tropics
• Winds that circulate around the poles
• Seasonal winds affecting monsoon regions
• Winds associated with cyclones

Which of the following best describes geostrophic wind?

• Wind caused by ocean currents
• Wind affected by friction near the surface
• Wind resulting from a balance between the Coriolis force and pressure gradient force
• Wind flowing along the equator

What does the Beaufort Scale measure?

• Atmospheric pressure
• Wind speed
• Air temperature
• Humidity levels

What effect does the pressure gradient force have on wind?

• It stops wind from moving
• It creates wind by causing air to move from high to low pressure
• It slows wind due to friction
• It deflects wind due to Earth's rotation
