The railroad tracks are parallel, because they go the same direction and don't intersect
Answer:
The answer is Option C: Index fossils.
Explanation:
Index fossils are used to identify geologic periods or faunal stages in rock layers. These fossils must have a wide geographic distribution and manifest obvious evolutionary trends to help geologists and others who need this geological data to better understand the time scale and to pinpoint a time period. For example, ammonites were common during the Mesozoic Era, but they were extinct by the Cretaceous period. Geologists would use ammonites to help determine this time frame if present.
The correct answer is - c. Hispania.
Hispania is just a latin term for the name Spain, though it has to be taken in notice that the Spanish people don't call the country Spain, but it is Espana in their own respective Spanish language, which is essentially the same, just that the English term is adjusted to the English language.
The crust is the part you walk on, and it's the surface of the earth.
Answer:
Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)
Not by using those measures as is (sides of a triangle with 25, 144 and 169).
Explanation:
A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.
The hypotenuse measurement squared is equal to the squared measurements of the other two sides:
c² = a² + b²
And those squares do verify the equation:
169 = 144 + 25
So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.
