The upstream of a river can be determined by..
the direction of the points of the V shapes on contour lines.
Good luck! :)
The units that are used <span>in space because metric units are too small would be: The astronomical Unit (A.U)
In space, the unit measurement is often used to measure the distance between planets or between stars.
Since the distance between these objects are very large, using metric units to measure it would be inefficient</span>
The Seine river
Did you hear about the guy who dived in to a river in France? He was in-Seine!
Insane. Get it? No? OK...
Sediments is most likely to be as a result of the interaction.
As wind and water are both weathering agents that cause the fragments of rocks to loosen,under the pull of gravity the fragments will fall off and sediments will be formed.
Reason why these are incorrect:
Lava and magma- Rocks has to be molten under an extremely high temperature to turn back into magma of lava,as the high
temperature is not present,the formation is impossible.
Metamorphic rock- It requires either high temperature or high pressure to lead to the formation of metamorphic rock, however the conditions are not present, thus this is incorrect.
Details of weathering:
The water would seep into the joints of the igneous rock as it is well-jointed,and carry out chemical weathering.
The materials such as feldspar and mica are nit weather-resistance hence easily loosen after weathering take place,causing the fragments to fall off.
Hope it helps!
Answer:
II and III
Explanation:
A species is classified as endangered when it comes to a situation where the number of individuals within the species is so low that it might not be enough for it to reproduce properly and survive. Also, when species is listed as endangered, the chances are very high that the species will go extinct.
In order for the species to be saved, there are numerous methods that are used:
- One thing is to make the hunting of the species illegal, usually making a very strict law that would fend off anyone tempted to do so.
- Creating a special program for monitoring the species, where every individual will be tracked, constantly checked, and protected on the ground.
- Any entry into the area where the species lives to be forbidden, except for scientific goals related to the species, and even for it to have a species permit.
Unfortunately, this doesn't always have the wanted effect, and despite all efforts some species go extinct, like it is the example with several species of rhinos in the past century. On the other hand, there are species that seem to be extremely resilient, and despite having very low numbers, they manage to survive, even if they don't have any particular rise in their populations, like it is the examples of the Iberian lynx and the Balkan lynx.
Very often, the method of breeding individuals in captivity of a species that is endangered is used. This is done so that there are controlled circumstances and no danger for the offspring, thus to maximize the chances of their survival. By using this method though, special programs are needed afterwards in order to prepare the young ones for life in the wilderness, which is not always successful.
