7) explain how tsunamis are formed. how do tsunamis change the surface of the earth?

tsunamis form from tectonics plates of the earths surface slip, releasing a massive amount of energy into the water. this energy travels up to the surface, displacing water and raising it above normal sea level. but gravity pulls it back down, which makes the energy ripple outwards horizontally, then the tsunami is born moving over 500 mph. these can begin from an earthquake, volcanic activity, or lands slides.

Explanation:

i just know ok?

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
