After reviewing the chart you posted, I can give the correct chart that will best describe the landscape category and the general bedrock structure, type, and composition of the New York States Catskills.
The best chart to describe the Catskills will be chart number 1. The landscape is plateau, the bedrock structure is horizontal, the bedrock type is sedimentary, and the bedrock composition is limestone, shale, and sandstone.
d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.
Explanation:
The magma is spilled from the mid-oceanic ridges and spreads onto the seafloor creating a newer seafloor.
This is why it's called as the divergent boundary due to the spreading of magma on both sides of the floor. Grabbo is a coarse-grained mafic intrusive igneous rock and is formed at the oceanic ridges.
