In a series of rock layers, a geologist finds fossils of a lizard-like dinosaur and a fern-like tree in layers that are 1.0 m and 1.5 m deep. However, in a layer that is 2.0 m deep, he finds fossils of bony fish and shellfish.

 

Which explains his findings?

 

 A.

The ancient sea dried up and became land.

 

 B.

The continent shifted to a polar region.

 

 C.

An asteroid hit the area, causing the dinosaur to become extinct.

 

 D.

The ancient land area was invaded by a sea.

  D is the right answer for this question. The water the fish and shellfish lived in either dried up or drained away, and over time other growth and erosion/deposition built up the soil levels over that location. Those newer soils contain the land animal remains.

 D is the right answer for this question. The different chemical compositions of minerals are as bountiful as people on the earth. Many minerals have amorphous (without clearly defined shape or form), though the vast majority have distinguishable shapes and cleavages allowing for proper identification. Organic just means their chemical compositions include organic elements like carbon, magnesium, potassium, sulfur, etc; not all minerals contain organic elements
