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.
Answer:
The presence of mustones by curiosity rover indicates chances of ancient life.
Explanation:
- The Yellowknife bay is a geologic formation of the Gale crater on the planet Mars and NASA named the rover as a curiosity. Its primary goal was to assess the potential habitability and whether the mars are capable to support life.
- The presence of the mudstones in the geologic depression area on mars leads to its name as Yellowknife i.e the capital of the northwest territory of Canada.
- The findings of the mudstone from the stepped bedded stata indicate the clay minerals that show the presence of water and claims that an ancient creator was found on in this region and these indicators of a potential mafic source of origin of deposition.
It went from a great power to an isolationist nation, much like japan.
D. vacuum packing
Explanation:
The best food preservation technique Andrea should use is vacuum packing.
Vacuum packing is a process in which food substances are preserved in seals where air has been removed.
- Since this is food product, vacuum packing the tomato will sustain the nutritional content of the tomato.
- Inside the vacuum, the tomato can ripen on its own as the hormones are stimulated to start working on their own.
- The organisms which are component of the dirt will not survive the packing due to the absence of oxygen for their life processes.
