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:
Smallpox has had a major impact on world history, not least because indigenous populations of regions where smallpox was non-native, such as the Americas and Australia, were rapidly decimated and weakened by smallpox. During the 18th century the disease killed an estimated 400,000 Europeans each year, including five reigning monarchs, and was responsible for a third of all blindness. After successful vaccination campaigns throughout the 19th and 20th centuries, the WHO certified the global eradication of smallpox in December 1979. Smallpox is one of two infectious diseases to have been eradicated.

Answer:
The correct answer is C. This maps represents the triangle trade.
Explanation:
The triangular trade was a slave trade in which manufactured goods such as alcohol, metal containers, clothing and firearms were transported from Great Britain (especially Liverpool). Cargo transported in Africa was exchanged for slaves transported to America or the West Indies. The slaves were replaced with sugar, cotton, rum and tobacco. For the shipowner, the deal was risky but very profitable. Each stage was profitable and the cost of the ship could be recovered in just a few trips. The triangle trade was practiced on a full scale since the 17th century and reached its peak in the late 18th century.
