Well to find this out you need to make an equation
s+7=j
So for example if Johnny's sister is 15 then Johnny would be 22 because
s(sister's age) +7(number of years difference between their ages)=22(Johnny's age)

Explanation:
An understanding of the structure of the Earth is important for many reasons
1. It can help us understand things that happen on the surface, like the magnetic field. The structure of the Earth explains that.
2. Things like tectonic plates severely affect the planet, such as the creation of many natural disasters. Understanding them helps us better prepare and anticipate them.
3. Understanding the structure of the Earth can help us identify the location of important natural resources (like different metals)
4. In the production of things like geothermal energy we need to understand the Earth's structure to know where we will get the most heat
