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.

Explanation: To calculate the mass of 1 Xe-atom , we will require atomic mass of Xe which is 131.29amu.
This atomic mass is the mass of 1 mole of 1 Xe-atom. One mole of Xe-atom is 
atoms of Xe. We will use this relation to convert Mass of Xe-atom into grams.

Answer:
electroluminescence is a production of light by the flow of electrons, as within certain crystals. An example is at most resataurants with a bright sign that either says open or closed.
Explanation:
If U-235 decays into Cs-135 and 4 neutrons, the other nuclide that will be produced is Rb-96 (option D).
<h3>What is radioactive decay?</h3>
A radioactive decay is the process by which an unstable large nuclei emit subatomic particles and disintegrate into one or more smaller nuclei.
According to this question, a radioactive material Uranium- 235 undergoes radioactive decay into Cs- 135 and 4 neutrons (1/0n).
This means that the mass of the products we have is 135 + 4 = 139.
The mass of the nuclide left must be 235 - 139 = 96, hence, the other nuclide that will be produced is Rb-96.

Answer:
For your first question, Curium does not occur naturally on Earth, meaning that it is not produced naturally on Earth. However, it can be formed in nuclear reactors.
For your second question, Curium has been used to provide power to electrical equipment used on space missions, but doesn't seem to be that important overall.
