the two main practices in science are supposition & fallacy.

true
false

Explanation:

• Question 4: Geoscientists, who deal with Earth - related matters, need to uphold high ethical standards in their work regarding Earth's stewardship. Making a great deal of money and planning to move off - planet is not relevant to their core role.
• Question 5: The first step of the Scientific Method is making an observation, not creating an experiment.
• Question 6: The Earth is an open system as it exchanges both matter (e.g., meteorites entering, gases escaping) and energy (solar energy input, heat radiation output). A human is a closed system in the context of matter exchange on a large scale (while it exchanges energy with the environment), as it does not freely exchange matter with the outside in the same sense as the Earth.
• Question 7: The main practices in science are observation, hypothesis - formation, experimentation, and analysis, not supposition and fallacy.

Answer:

• Question 4: B. adhere to the highest ethical standards in all professional activities
• Question 5: False
• Question 6: A. The Earth/ A human
• Question 7: False
