Answer:
The fish did not yet exist when the old layers of rocks were deposited. In fact, animals with hard parts did not evolve until about 600 million years ago, which is only about 13% of the 4.5 billion year age of the Earth. Multicellular animals without hard parts left tracks in older sediments, but had no fossilize-able body parts.
Explanation:
A good topic idea that could be used can be about ecosystems. Such as how geographic area, plants, animals, weather and landscape make up the types of organisms in that specific ecosystem.
Answer:
B. the long beak helps the bird eat insects.
<em>Rocks erode and sediment is deposited, and No sediment is deposited over a long time.</em>
<u>Explanation:</u>
The most common reason for the formation of <em>uncomformity is erosion</em>. The <em>times of formation of the rocks</em> above and below the uncomformity are different when no sediment is deposited over a long time.
The rock above the uncomformity are younger than the rocks below the uncomformity. Types of uncomformity are <em>angular uncomformity, discomformity and non comformity.</em>
In angular discomformity horizontal sedimentary rock layers are formed above sedimentary rock layers that are in tilted position. Discomformity lies between two <em>horizontal sedimentary rock layers</em>. Non comformity lies between<em> sedimentary and igneous rock layers or metamorphic rocks.</em>
