Are You Smarter Than a Sixth Grader?

The Earth's four main spheres are the geosphere (the solid Earth, including rocks and land), the hydrosphere (all the water on Earth), the atmosphere (the layer of gases surrounding the planet), and the biosphere (all living things). What I don't understand is how this relates to any of the answers. I answered this question with "Nitrogen and Oxygen" because those two gasses make up most of earth's atmosphere. Hydrogen and Helium are only minor components of earth's atmosphere.

5 / 7. What are earths 4 spheres! Sounds like nonsense to me! Also, what is a producer? This question is a bit vague! Not much of a quiz with only 7 questions!

A few questions made zero sense and I doubt a child could answer.

6/7, but as with everyone else, question 7 makes no sense whatsoever.

The last one me too.

the last one makes no sense to me.

Yes billyboy915,

Number 7 sounds like a question meant for the Atmosphere of the SUN.

5 / 7. What are earths 4 spheres! Sounds like nonsense to me! One better than last time!

Thanks for the answers!

I'm in good company. No one seems to understand #7.

The last question just makes no sense.

I was hitting 100% until I got to that cryptic question #7! Did that one make sense to anyone?
