How are the ionic and covalent bonds alike?
What will be an ideal response?
Both the ionic and covalent bonds are electrical forces holding atoms tightly together. Recall that there is not a black-and-white distinction between the two. Rather, there is a gradual change from covalent to ionic as the atoms that bond are found farther apart in the periodic table.

What will be an ideal response?
The classical economic paradigm and the new ecological economic paradigm differ in the way that
A) each views the land, either as a resource within the human economy (classical) or as something that encompasses the economy (ecological).
B) the value of capital is assessed, either in dollars (classical) or as resources that can be mined from the Earth (ecological).

D) labor and capital are assessed, either counting the total labor and capital resources available (classical) or that which is in use in operations (ecological).
Volcanoes are generally not preserved in the geologic rock record as they are eroded away. However, the various materials erupted from volcanoes are often found preserved in the rock record
How could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples and briefly discuss if some materials may be linked to different types of volcanoes. What will be an ideal response?
