Answer:Sea Floor Spread is where the oceanic crust splits to form new crust on the earth forming ridges.
Continental slide is when tectonic plates slide past one another formed at the fault line causing earthquakes.
Transform boundaries can be explained by showing what happens after they slide almost like how after an earthquake the houses are destroyed and some have sunk into the grounds fault line.
Continental Crust is the crust of the earth that us humans and animals live on formed by divergent boundaries in the crust.

Answer:
The answers are Fluorine and Francium.
Explanation:
Fluorine has the highest affinity for electrons while Francium has the lowest affinity for electrons. This can be measured by the electronegativity of each one, where Fluorine is the most electronegative element. This can also be seen by the accommodation of elements in the periodic table.
After two half-lives or 60 years, 7.5 g of the element will be left.
<u>Explanation:</u>
<u>Half-life:</u>
- In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
- In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
- After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
- And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
- After two half-lives or 60 years, 7.5 g of the element will be left.
