hydrogen (H) atoms and an oxygen (O) atom bond together to make water (H2O). What term best describes H2O? Why?
compound (two different elements chemically combined)
or
molecule - two or more atoms chemically combined WITH a covalent bond

In the Arctic, melting sea ice exposes more dark ocean, which in turn absorbs more heat and causes more ice to melt...the cycle continues.
This is an example of

Give a clear example of how the biosphere and the atmosphere are interconnected/ depend on each other.
EX: Organisms, such as plants depend on the atmosphere for carbon dioxide to go through photosynthesis, and release oxygen back into the atmosphere.

How do chemical bonds form?
By the sharing or exchange of electrons between atoms.

Caption the image below using the terms tectonic plate, landforms.
The caption should illustrate the relationship between the terms/ how they are related.
tectonic plates colliding against each other create landforms such as mountain ranges.

What is the cause and effect of eutrophication?
Cause: Excess nutrients in water from agricultural runoff, sewage, and stormwater discharge.
Effect: Oxygen depletion, leading to fish kills and the formation of dead zones.
