Understanding Weather and Climate

Which layer of the atmosphere is closest to the Earth's surface?

• Stratosphere

• Troposphere

• Mesosphere

• Thermosphere

Identify three sources of greenhouse gases in the atmosphere.

• burning fossil fuels

• photosynthesis

• volcanic eruptions

• wind energy

How does climate change affect weather patterns globally?

• Climate change only affects temperatures, not precipitation.

• Climate change causes more extreme weather events and alters precipitation patterns globally.

• Climate change has no impact on global weather systems.

• Climate change leads to more stable weather patterns worldwide.

What is the primary reason for the formation of a land breeze?

• Cool air from the ocean moving towards the land

• A temperature difference between land and sea causes a breeze from the land to the sea.

• High pressure over the land compared to the sea

• Wind patterns caused by the rotation of the Earth

Describe the characteristics of monsoon seasons.

• Monsoon seasons have consistent temperatures throughout the year.

• Monsoon seasons are defined by strong, cold winds and minimal rainfall.

• Monsoon seasons are characterized by dry weather and low humidity.

• Monsoon seasons are marked by heavy rainfall, high humidity, temperature variations, and a shift in wind patterns.

What is the difference between a land breeze and a sea breeze?

• A land breeze blows from land to sea at night, while a sea breeze blows from sea to land during the day.

• A land breeze occurs during the day, while a sea breeze occurs at night.

• A land breeze is stronger than a sea breeze all the time.

• A land breeze and a sea breeze are the same phenomenon.

What are the effects of the Amihan and Habagat winds in the Philippines?

• Amihan causes drought and heat; Habagat brings clear skies.

• Amihan leads to increased humidity; Habagat causes cooler temperatures.

• Amihan brings thunderstorms; Habagat results in dry weather.

• Amihan brings cooler, drier weather; Habagat brings heavy rainfall and humidity.

Explain the role of the Intertropical Convergence Zone (ITCZ) in weather patterns.

• The ITCZ is primarily responsible for polar weather patterns.

• The ITCZ has no impact on global climate systems.

• The ITCZ causes droughts in tropical regions.

• The ITCZ plays a crucial role in weather patterns by causing significant rainfall and influencing tropical climates.

How does high pressure create wind that moves to low pressure?

• High pressure traps air, preventing it from moving to low pressure.

• Wind moves from low pressure to high pressure due to temperature differences.

• High pressure causes wind to move in all directions equally.

• High pressure creates wind that moves to low pressure due to the difference in air density and pressure, causing air to flow from high to low pressure areas.

What are some impacts of climate change on sea levels?

• Decreased sea levels due to increased rainfall.

• Stable sea levels with no significant changes.

• Rising sea levels caused by volcanic activity.

• Rising sea levels due to thermal expansion and melting ice.
