Sinkholes form when limestone is slowly dissolved by acidic groundwater over geologic time. ... This process of dissolution can create large cavities in limestone. A sinkhole forms when the roof of a cavity in the limestone collapses and creates a depression at the land surface.

densk [106]

Answer:

difference:

1. The generation mechanism is different, the mechanical wave is generated by mechanical vibration; the electromagnetic wave generation mechanism is also different, there is the periodic movement of electrons (radio waves); the outer electrons with atoms are generated after being excited (infrared, visible, ultraviolet) The inner electrons with atoms are generated after excitation (roentgen rays); the nuclei with atoms are generated after excitation (gamma rays).

2. The propagation mechanism is different: the mechanical interaction between the particles and the alternating induction of the electromagnetic field.

3. Mechanical waves have both transverse waves and longitudinal waves; electromagnetic waves are material waves and belong to transverse waves.

4. The influence of the medium on the propagation speed is different

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children

vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

║ A ║O

O║AO║OO

There is a 50% of probability of having O offsprings with AO and OO.

║ A ║A

O║AO║AO

O║AO║AO

With AA and OO, the probability is 0%

║ A ║O

A║AA║AO

O║AO║OO

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.

Explain how the ages of the rocks on the ocean floor support the theory of seafloor spreading

Dafna11 [192]

The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.

Explanation:

The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor. The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.

The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.
