I am pretty sure it is C but correct me if I'm wrong hope this helps.
It’s B, they sometimes do follow the borders of countries
Answer:
A sediment deposit close to the continental rise having a coarse material overlaid by successively finer materials of non marine origin is called a turbidite.
.
Explanation:
Turbidity current is the movement of sediment laden water . It is caused by the high density nature of sediments . The current is prevalent in oceans and lakes and it one process that transport sediments from coastal areas to deep sea.
The sediments in the current makes the flow denser and very rapid. The rapid nature of the movement of this sediment laden water causes a kind of selective deposition in deep sea. The more coarse sediments are deposited before less coarse sediments. The sediments deposited fines upward. The coarsest sediments are found at the bottom and it fine upward.
Turbidites are sediments deposited by turbidity currents which gradually change from coarse grain to fine grain sediments. The continental rise is the boundary between continents and the deep part of the oceans. This area is usually laden with sediment deposited by turbidity current. The sediments laden water moves downhill.
Answer:
"All of them except last one."
Explanation:
All of the given options represent NASA future projects:
- Use a probe to collect data- Parker Solar Probe will be the first-ever mission to study the Sun from such a small distance. The spacecraft will travel directly into the Sun's atmosphere about 4 million miles from the surface.
- Improve aviation technology- NASA is currently working on the development of the new experimental aircraft X-plane which will prove the dramatic benefits of advanced technologies in piloted flight.
- Conduct research from a space station- Humans are already living and working on board of the International Space Station which is one-of-a-kind research laboratory in micro gravity. A portion of the astronauts time aboard the space station has been designated for national laboratory investigations.
- Collect samples on an asteroid- First asteroid sample return mission, OSIRIS-R Ex, arrives at the near-Earth asteroid Bennu in December 2018 and should return a sample for study in 2023.
- Conduct an unmanned space mission- In Sight Mars lander is set to study the planet’s interior. The Mars 2020 rover will search for signs of past microbial life, gather samples for future return to Earth and investigate resources. The James Webb Space Telescope will be the premier observatory of the next decade, studying every phase in the history of our Universe in infrared
Russia, Kazakhstan, Turkmenistan, Iran and Azerbaijan all border the Caspian Sea.
