A. For the south china sea! hope this helps!!
The correct answer is - unequally distributed.
The water on the planet is not distributed equally. Be it the salt water or the fresh water, there's big differences from place to place.
The salt water for example, is much more abundant on the Southern Hemisphere, while it is much less found on the Northern Hemisphere.
The freshwater though, has much bigger differences on much smaller spaces. While places like the northern half of South America or most of Europe are abundant with water, there's places do not have it at all, like the Arabian Peninsula. The Arabian Peninsula actually doesn't have a single stream or river that have a constant flow, while on the other hand, you have a very small country like Macedonia that has over 2,000 streams and rivers on just above 25,000 km².
The statement "Mass extinctions have occurred several times on Earth" explains the indication of the fossil record.
<h3>Indication of Fossil fuels:</h3>
Paleontologists are fascinated by the evolution and extinction of fossil species throughout geologic history. To do so, they look at all the fossils that have been preserved in sedimentary rocks.
The fossil record is what we call it. Paleontologists have been collecting fossils from sedimentary rock layers all over the world for over two centuries.
Their goal is to figure out how species have evolved over geologic time. It can be used as a geologic timescale once the succession is established.
Then, if a specific fossil is discovered in a rock, you can determine where it belongs on the geologic timescale.
Therefore, the correct option is the third sentence.

Explanation:
Ecosystems exist at a range of scales and involve the interaction between biotic and abiotic components. An example of a small scale UK ecosystem to illustrate the concept of interrelationships within a natural system, an understanding of producers, consumers, decomposers, food chain, food web and nutrient cycling.
Answer:
The layers constitute fossils, calcium carbonate rocks
Explanation:
- Limestone is a biologic sedimentary rock and is formed by the collection of shells and debris. It can also be formed by the chemical process of sedimentary and precipitation of calcium carbonate.
- The limestone is composed of calcium carbonate, calcite, feldspar, and Quartz. Limestone represents karst topography and consists of the chemical composition of clay, iron, feldspar, and quartz. These are arranged in layers.
