This is in science about plate tectonics plz help: Some regions of the Earth are more likely to have earthquakes, volcanoes, or hot springs than other regions. What do these places most likely have in common? A.
They are regions with big cities.
B.
They are regions where tectonic plates meet.
C.
They are regions in the northern hemisphere.
D.
They are desert regions.

B

Explanation:

Tectonic plates lead to all of these geographical occurences. It is when these plates interact with each other that we experience these things.

B. They are regions where tectonic plates meet.

Explanation:

Places, where tectonic plates meet, are most likely going to cause earthquakes, volcanoes, and etc. The reason for this is that when two tectonic plates meet, it is going to crash. When things crash, things are going to end up vibrating and smushed. In this case, it will be an earthquake, and when it is smushes, it will build or create a volcano.

the answers would be

the first one and the second one

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
