What two primary liquids were proposed as candidates for forming the channel on Mars?
Lava and water
What is a simplified representation of a real-world object, system, or process?
Model
What part of a scientific argument explains how the evidence supports the claim using scientific principles?
Reasoning
What two components are necessary for a planet to be considered habitable?
Liquid water and an energy source
Which four planets in our solar system are classified as rocky planets?
Mercury, Venus, Earth, and Mars
What term describes a path or physical depression that guides and directs the flow of water?

candle wax
What is the reasoning: Cats are better pets than dogs for people seeking low-maintenance, adaptable companions. Pet care studies show that cats require only 20 to 30 minutes of daily play, self-groom for up to half their waking hours, use indoor litter boxes, and cost significantly less in annual care than medium-to-large dogs, which demand 1 to 2 hours of daily outdoor exercise. Because cats manage their own hygiene, eliminate waste indoors, and require less dedicated exercise time, they fit much more seamlessly into busy schedules, tight budgets, and smaller living spaces. Therefore, their independence and cost-effectiveness make them the superior choice for modern lifestyles.
