8. Where does much of our information on planets come from?

Idon't know. the question you are trying to ask doesn't make sense.

Place the point of the compass on point b and draw an arc that intersects  be¯¯¯¯¯  , using    ab    as the width for the opening of the compass.  hope it

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.
