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)
I believe it's globular and open are the main types.
<span>National symbols of Canada are the symbols that are used in Canada and abroad to represent the country and its people. Prominently, the use of the maple leaf as a Canadian symbol dates back to the early 18th century, and is depicted on its current and previous flags, the penny, and on the coat of arms (or royal arms). Hope this will be useful im sorry if its not</span>
If such an earthquake was to strike L.A., the epicenter and the magnitude would be <u>Los Angeles</u><u> </u>and <u>7.8 </u><u>o</u>n the Richter scale respectively.
<h3>What is the epicenter and magnitude of an earthquake?</h3>
The epicenter of an earthquake is the place on the surface of the Earth where the earthquake is first detected which in this case is Los Angeles.
The magnitude is measured on the Richter Scale and in this case is 7.8 on that same scale which means it was quite a strong quake.

The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.
Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.
