Answer:
A) sea level drops; land subsides
Explanation:
The sea is the final destination of all streams on land. All streams empty into seas which are the basins that collects all terrestrial materials.
The base level is the lowest level to which a river can erode its channel. The base level is greatly influenced by what happens to a sea.
When a river reaches its base level, erosion ceases. If a river is young and set above its base level, we see a rapid rate of erosion.
A sea, the final basin of depostion of rivers controls the base level to a very large extent. When there is a tectonic movement and a sea subsides. It becomes more deeper and lower. Sea level also falls and materials grades seaward. A river would cut rapidly along its channel and its bed to measure up to the level of the ocean.
Therefore, we see a very rapid rate of erosion of channels when sea level falls and the earth sags downward. This would lead to a lower base level.
When sea level rises and there is a tectonic uplift, rivers erode their channels less and begins to aggrade materials. The base level also rises.

<u>Answer:</u> transitional
<em>Gerobatrachus hottoni mostly like to be transitional fossil.</em>
<u>Explanation:</u>
<em>Gerobatrachus refers to an extinct genus of amphibamid temnospondyl, which thrived in the initial Permian, that is, about 290 Mya</em>, in the region, which is now known as Baylor County, Texas.
The transitional form of fossils is those that <em>demonstrate the intermediate form between the two distinct living species, </em>it could be in a form of an ancestor and its descendants.
It has been believed that the reptiles creatures as frog have evolved from the <em>previous ancestor of primitive amphibian tetrapod subclass known as Temnospondyl. </em>
The number of degrees of longitude that separate New York City and Reno, Nevada is 120 – 75 = 45 degrees of longitude. The time difference can be calculated by dividing it by 15 degrees because for every 15 degrees there is 1 hr difference. 45 / 15 = 3 hr difference
