Science Exam Review Test

What is the main difference between weather and climate?

• Weather is short-term; climate is long-term

• Weather is always hot; climate is always cold

• Weather is measured in decades; climate is measured in hours

• Weather never changes, while climate changes daily

Which of the following is an example of weather?

• The Arctic is generally cold year-round

• Africa is mostly warm throughout the year

• The Philippines has a tropical climate

• It rained in Cebu yesterday

Weather is like mood, while climate is like personality. What does this analogy mean?

• Weather is permanent, while climate changes every day

• Weather is short-term and can change quickly, while climate shows long-term patterns

• Weather and climate are both permanent traits

• Weather depends on personality, while climate depends on mood

A student records that it was hot and sunny for 3 days in Manila. Can this be used to describe the climate of Manila? Why or why not?

• Yes, because 3 days is enough to show the long-term pattern

• Yes, because Manila is always sunny and hot

• No, because climate requires long-term data (30+ years)

• No, because weather and climate mean the same

Which of the following pictures best shows weather?

• 
• 
• 
• 

Which part of Earth receives the most direct sunlight?

• The Poles

• The Equator

• The Mantle

• The Oceans

What gas is the most common greenhouse gas released by burning fossil fuels?

• Carbon dioxide (CO₂)

• Nitrogen (N₂)

• Oxygen (O₂)

• Helium (He)

Which of the following is a natural greenhouse gas?

• Nitrogen (N₂)

• Oxygen (O₂)

• Carbon dioxide (CO₂)

• Argon (Ar)

Why is the Philippines generally hotter than countries near the poles?

• It has more cars and factories

• It is near the equator

• It is closer to the sun

• It has more forests and mountains

How do greenhouse gases make life possible on Earth?

• They destroy harmful UV rays

• They remove all heat from the Earth

• They block sunlight so the Earth won’t overheat

• They trap enough heat to keep Earth warm
