Which of the following sciences are similar?

Question

biology, ecology, earth science, or astronomy?

I have to make an essay on two of them. Here's what I'm suppose to do, just in case this helps you:

Describe what you believe any two of these sciences to be and their scope. What are the differences between them and how do they overlap?

Answer 1

its bio,eco = Biology is the study of life. Eco is the study of life in how it effects other life.

earth,asto = earth examines rocks, earth and substances. Asto examines planets.

Answer 2

ecology and earth, hm but maby ecology n bio

Answer 3

any of these things are related. just pick the one that would be easiest for you to argue. I would choose earth science and astronomy, because many things, such as climate and tides, are dependant on our distance from the sun- which ties into astronomy.
