Answer:
(4) period of revolution
Explanation:
have, at one time, been covered by water?
(1) Volcanic eruptions contain large amounts of
water vapor.
(2) Coral reefs formed, in the past, along the
edges of many continents.
(3) Seafloor spreading has pulled landmasses
apart and pushed them together.
(4) Sedimentary bedrock of marine origin covers
large areas of Earth’s continents.
Statement 4, 'Sedimentary bedrock of marine origin covers large areas of Earth's continents' best supports the inference that most of Earth's present-day land surfaces have, at one time, been covered by water because these rocks are formed from the sediments gathered on the seafloor, indicating that the area they are found in was once underwater.
The statement that best supports the inference that most of Earth's present-day land surfaces have, at one time, been covered by water is '(4) Sedimentary bedrock of marine origin covers large areas of Earth's continents'. Here's why:
Sedimentary bedrock of marine origin, also known as marine sedimentary rocks, are often clear indicators that the area they are found in was at some point underwater. These rocks form as a result of the accumulation of sediments, such as sand, silt, and organic material, on the floor of oceans or seas. Over time, due to processes such as compaction and cementation, those sediments transform into rock. Therefore, wherever we find this type of rock, we can infer that this region was once submerged underwater.

Answer:
THE 1883 KRAKATOA VOLCANIC ERUPTION
Resources:
1. Mary Bagley, “Krakatoa Volcano: Facts About 1883 Eruption,” LiveScience (September 14, 2017).
2. Simon Winchester, Krakatoa – The Day the World Exploded: August 27, 1883 (New York: HarperCollins, 2003).

(Krakatau | Volcano World | Oregon State University)
Explanation:
The island of Krakatau is located in Sunda Strait between Java and Sumatra. It is part of the Indonesian Island Arc. Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward toward mainland Asia. The Krakatoa island is found to be about 3 miles wide and 5.5 miles long (9 by 5 kilometers). As at the time of this eruption in 1883, the region was part of the Dutch East Indies; it’s now part of Indonesia. Location: Krakatoa, Anak Krakatau Island, Pulau, South Lampung Regency, Lampung, Indonesia, Asia.
In August 1883, the eruption of Krakatoa, (or Krakatau), was one of the most deadly volcanic eruptions of modern history ever recorded. It is estimated that more than 36,000 people died. The deaths recorded were as a result of the thermal injury from the blasts. Also, the victims were of the tsunamis that followed the fall of the volcano into the caldera below sea level. The temperatures dropped all over the world and the climate was affected because the eruption was so terrible.
b. Panama’s sole control over the Panama Canal
c. Frances abandonment of the Panama Canal project
d. Joint control of the Panama Canal and Los Estados Unidos
The main factor attributed to Panama's booming economy is that Panama's sole control over the Panama Canal.
The canal links the Atlantic and Pacific Oceans, saving ships from having to travel around South America. A new set of locks allowing larger ships to passage through the canal were opened in 2016.
The panama canal was built to lower the distance, coast and time it look for ships to carry cargo between the Atlantic and the Pacific Oceans. Before the canal, ships would have to go around the entire continent of South America.
The correct answer is option B.

The correct answer is - nonrenewable.
Even though lots of countries are making big efforts in reducing the usage of nonrenewable resources, mainly because of the harm they cause to our health and they damage the environment, still it is always the economic factor that doesn't allow that they are totally kicked out of usage. These resources are still cheaper than the renewable and inexhaustible resources, and a lot of investments and technological advance is needed so that these resources are able to outcompete the nonrenewable ones.
Answer:
Exhaustible and non renewable resources.

Answer:
The routes show that most of the slaves were going to the colonies in the Americas
Explanation:
The slave trade was very big during the colonial period. The Portuguese were the first ones to start buying slaves from Africa, and the world quickly spread around, so the other colonial powers started to do so. The main reason why the slave trade became so big was because the colonies in the Americas primarily had huge demand for labor force for the enormous plantations of cash crops. The slaves were seen as ideal labor force, as they were obtained easily, they were paid nothing for their work, but only provided simple shelter and food. This resulted in mass forceful migration of Africans toward the Americas, which in the time to come contributed to the culture and demographic composition of the New World.
