The correct answer is - wave erosion.
The sea stack, sea arch, and the sea caves, are all land features that have gradually been formed by the influence of the waves, or rather by the erosion that the waves have caused on them.
The sea stack is a land form very close to the coast, and it is manifested by solitary very steep rocks, or as group of very steep rocks, and they have formed because of the wave and wind erosion.
The sea arch is land form that appears as an opening in a cliff, being formed by the the wave refraction where the focus of waves goes on the sides of a headland.
The sea caves are openings deeper into the crust, where the waves managed to erode the softer rocks, and the water to penetrate deeper inside.
The atomic number,atomic mass,valence electrons and the formula for calculating the number of neutrons is also given.The following table has been completed below in the attachment.
Explanation:
Atomic Number:the number of protons /electrons present in the nucleus of an atom is called the atomic number.
Mass Number/Atomic Mass:the number of protons and neutrons present in a nucleus
<u>Example:</u>
;here;6 implies the atomic number and 12 implies the mass number/atomic mass
<u><em>No.of neutrons=Mass number-Number of protons</em></u>
Valence electrons:the number of electrons present in the outer most shell of an atom are called valence electrons
<u>Example:</u>If we consider a carbon atom;as its <em>e</em><em>lectronic configuration is2,4 and</em> it belongs to 4th group.Therefore the number of valency electrons in carbon is <u>4.</u>
Answer:
17 protons
19 neutrons
Explanation:
Chlorine will always have the same amount of protons, and that would be 17 protons.
The atomic mass will change according to how many neutrons are present.
Cl - 35 is comprised of 17 protons and 18 neutrons.
We want to find Cl - 36:
We simply add 1 neutron. 18 + 1 = 19 neutrons.
D) refracted
because , the light changes direction.. causing the penny to look bigger than it is.
