Answer:
Hi,
Geologists obtain indirect evidence about the earth’s interior by studying seismic waves produced.
Explanation:
Geologists are able to study the layers of the interior of the earth by observing the seismic waves patterns. The recorded data for the waves can show how the waves traveled through the earth and the path followed which will reveal the structure of the interior of the earth. The speed and magnitude of the wave can further reveal the characteristics of the earth’s interior.
Best wishes!
Answer:
Core.
Explanation:
The core is magnetic and is the cause of the Poles and the magnetosphere.
If you add the two lengths on the left, you can figure out that one side is 100 units and the base is 50. In the smaller triangle, the ratio of base length to side length should be the same. If the big triangle is 50:100, then the small triangles base should be 1/2 it’s side. 1/2 of 60 is...
30 units
Hope this helps :)
