Answer:
Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material.
Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.
Answer:
Let's assume that the erosion rate is "X/hour". The total volume of sand on a beach after 24 hours would be,
= total sand volume - (erosion rate per hour * 24)
= 1,278m - (X/hour * day)
Explanation:
Now assume that the erosion rate is 1 m per hour. Therefore, in 24 hours would be,
= 1,278m - (1/hour * 24)
= 1,278 - 24
= 1254 m.

Answer:
Elements in the same vertical column on the periodic table will have similar chemical properties and behave similarly in chemical reactions. These vertical columns can also be called groups/families.
