Answer:
On subduction zones
Explanation:
Explosives volcanoes are most likely to be found on subduction plate boundaries where one plate subducts (goes under) another plate. The subducting plate is usually a plate made of denser oceanic crust and the upper plate usually consists of less dense continental crust. Because of the composition of the magma and the high silica content found in the continental crust, these eruptions are much more explosive than the gentler basaltic flows characteristics of oceanic hotspot eruptions or undersea divergent plate boundaries.
The answer would be false
A slopping shelf will let the water flow while a steep shelf will slow the surge.
So it will likely result in a better storm surge impact
In the US, there was a trade system where in West Africa would capture and sell slaves to slave traders in the US or many other European countries.
Answer: Also known as the Circum-Pacific Belt, the Ring of Fire traces the meeting points of many tectonic plates, including the Eurasian, North American, Juan de Fuca, Cocos, Caribbean, Nazca, Antarctic, Indian, Australian, Philippine, and other smaller plates, which all encircle the large Pacific Plate.
Explanation:
Answer:
c. 2
Explanation:
Given that
Parent to daughter ratio = 1:3
Based on the above information, after considering the 1 half-life of radioactive isotope there is one-half of the real radioactive atoms of the parent left also the equivalent number of daughter atoms produced
Therefore after one half, the ratio between parent and daughter atom is 1:1
Now after the second half, half of the left parent atom would be transformed into the daughter cells
This remains a quarter of parent atom and 3 quarter of daughter atoms
So, the ratio of 1:3 would be shown after 2 half-lives
