Of the seven (7) continents, South America is the fourth (4th) largest.
Asia, Africa, and North America, in that order, are larger.
Antarctica, Europe, and Australia, in that order, are smaller.
Unconformity refer to a condition in which horizontally parallel strata of sedimentary rock are deposited into eroded layers.
the process that can cause uniformity are :
- Weathering
- Erosion
Hope this helps
I think the The answer is B
The cold water observed along the northern California coast in summer is mainly due to: upwelling .
- here Upwelling is a process in which deep, cold water rises toward the surface replaces warm water from the surface.
- Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
- Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
- Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.

Answer: event horizon </h2><h2>
</h2>
The event horizon is the <u>surface of a black hole</u>, it is the border of space-time in which the events on one side of it can not affect an observer on the other side.
That is, at this border also called "point of no return", nothing can escape (not even light) and no event that occurs within it can be seen from outside.
In this sense, on April, 10th 2019 this was demonstrated with the publication of the image, for the first time, of the event horizon of the black hole (which appeared as an orange glow ) in the M87 galaxy. This is the first time in human history a picture of a black hole is taken.
