b. Period of revolution increases, orbital velocity decreases
C. Period of revolution decreases, orbital velocity stays the same
d. Period of revolution decreases, orbital velocity increases

i think

1. continental slope

2. continental rise

3. continental shelf

mark me branliest, only got it 1 time

a. the production of carbon dioxide through the process of photosynthesis

i think its both a and b
