By observing how seismic waves are absorbed and refracted, scientist have been able to work out where the properties of the earth change dramatically. our understanding of the internal structures of the earth and the size of its core is based on these observations.
basically:
size of core
structure of the earth I.e. the layers of the earth
and I think the last one is how the internal structure is changing? not sure on the last one but its still a solid guess.
Well,not exactly. Longitude is the <em>angle</em> east or west of the Prime Meridian.
Answer:
Asteroids can cause great damage if they collide with Earth.
Explanation:
The above statement is actually the passage that is too broad in the passage. A "too broad" statement is one that lacks details and also too general. Such statements tend to cover generalize and cover many possible issues/topics. In such statement, different topics can fit within it.

The Great Barrier Reef is special because it is by far the largest reef in the world. It is consisted of around 2,900 individual reefs. The size of this reef is approximately as the size of Germany. There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.
Well to start off on a graph the x goes left and right and the y goes up and down. you always read coordinates (x,y), so -4 needs to go left and make -6 and the 2 needs to go up making 4 so your new coordinates are (-6,4)
