The correct answer is B. False
Explanation:
Russia is considered the largest country in the world, located in both Asia and Europe. In terms of population, most of the Russian population is now located in the western zone of the country or in Europe, which includes cities such as Moscow or St. Petersburg. Despite this, since the 19th century and especially during the Soviet Union period there were migrations of Russians eastward or towards the Pacific coastal zone, which led to the creation of Russian settlements in new zones.
However, in the last decades, this migration pattern has decreased and settlements in the east are still small in comparison to those of the west. In this context, the eastward migration has not been a huge phenomenon since 1991, and even if there is still migration and the government promotes this, it has not led to a lack of accommodations or restrictions, which makes the statement false.
Fossilization is a process that requires certain conditions so that it can take place. The climate is very important, a hot and wet place is not a place where there's a chance of finding fossils, while the places with permafrost are a much better candidate because the bacteria can not dissolve the organisms. The pressure also can play a vital role. A place that manages to keep the organisms safe from outside influence, like the tar pits, are excellent preservers. Also the structure of the organisms play a key role, a boneless organism is very hard to preserve and be fossilized, while an organism with bone structure has a bigger chance of being preserved.
Answer:
<u>D. Gradient decreases, discharge increases.</u>
Explanation:
- As steam is a body of water that carries rock particles and dissolved ions, discharge is measured in terms of volume/time (m3/sec). So when a river discharges its flow from a headwater to its mouth the velocity increases in the downstream direction.
- Thus the river load-carrying capacity increases downwards and so does the discharge rate. The discharge rate can also be influenced due to the rainfall patterns, volume of water and velocity of flow.
- Rock types also impact the streamflow if it is a porous rock, the surface will absorb more of moisture content and comparative more will be the water penetration towers the mouth of the flow.
