Module 2 Lesson 5

What is a greenhouse gas?

• A gas that absorbs and emits radiation within the thermal infrared range

• A gas that only absorbs ultraviolet radiation

• A gas that is only found in greenhouses

• A gas that is only emitted by plants

DOK Level 1: Recall

Which of the following is NOT a key greenhouse gas?

• Carbon dioxide

• Nitrous oxide

• Oxygen

• Methane

Tags

DOK Level 1: Recall

How does Earth's magnetic field contribute to making Earth habitable?

• It provides oxygen to the atmosphere

• It protects Earth from the Solar Wind and cosmic charged particles

• It increases Earth's temperature

• It creates liquid water on Earth's surface

Tags

DOK Level 2: Skill/Concept

What is the significance of liquid water on Earth's surface for habitability?

• It is a source of oxygen

• It moderates Earth's temperature

• It is necessary for life as we know it

• It reflects sunlight

Tags

DOK Level 2: Skill/Concept

Explain why the presence of oxygen in Earth's atmosphere is crucial for life.

• Oxygen is a greenhouse gas

• Oxygen is necessary for cellular respiration in most life forms

• Oxygen blocks harmful UV radiation

• Oxygen is the main component of Earth's atmosphere

DOK Level 3: Strategic Thinking

What is the approximate extent of Earth's magnetic field in the direction toward the Sun?

• One Earth

• Five Earths

• Ten Earths

• Thirty Earths

Tags

DOK Level 1: Recall

Which of the following statements about Earth's magnetic field is true?

• It is weaker than the Solar Wind

• It can extend as far as the orbit of the Moon away from the Sun

• It is only present during the day

• It is responsible for Earth's gravity

Tags

DOK Level 2: Skill/Concept

Identify the two main properties of Earth's atmosphere that contribute to its habitability.

• Presence of nitrogen and carbon dioxide

• Presence of oxygen and moderate temperatures

• Presence of water vapor and high pressure

• Presence of methane and low pressure

Tags

DOK Level 1: Recall

Discuss the role of moderate temperatures in maintaining liquid water on Earth's surface.

• Moderate temperatures prevent water from evaporating

• Moderate temperatures allow water to exist in all three states

• Moderate temperatures ensure water remains in liquid form, essential for life

• Moderate temperatures increase the salinity of water

DOK Level 3: Strategic Thinking

Which of the following gases is primarily responsible for the greenhouse effect on Earth?

• Nitrogen

• Oxygen

• Carbon dioxide

• Argon
