What is the main purpose of investigating a channel on Mars?

• to study volcanoes

• to decide if we can live on Mars

• to determine if it was formed by flowing water or flowing lava

• to find out about rocks

How can scientists gather more evidence about whether water or lava formed the channel on Mars?

• By observing the behavior of water and lava in a laboratory setting
• by studying landforms on Earth and comparing them to those on Mars

• By asking the Martians who live near the channel
• By tasting the water and lava to see which one matches the composition of the channel

What do models represent in scientific investigations?

• Unrelated to real-world phenomena or systems
• Simplified representations of natural processes

• Exact replicas of real-world phenomena or systems
• Complex versions of real-world phenomena or systems

Why do landforms provide evidence about the past?

• Landforms are unrelated to past events
• Landforms are only formed by human activities
• Landforms remain after the geologic processes that formed them have ceased

• Landforms have no impact on the environment

What type of rock is typically found near channels made by flowing water on Earth?

• Time travel
• Global warming

What did the rover Curiosity discover near the channel on Mars?
