Answer:
Zicrons
Explanation:
The oldest of the zircons in the study, which came from the Jack Hills of Western Australia, were around 4.3 billion years old—which means these nearly indestructible minerals formed when the Earth itself was in its infancy, only roughly 200 million years old.
Answer: It refers to the decline in travel time between geographical locations as a result of transportation, communication, and related technological and social innovations.
Explanation:
Answer:
The rocks at the bottom of the ocean are younger than the rocks on the continent. This can be pessible due to the process called Continental Drift.
Explanation:
For a long time the human being wondered what would be the age relationship between the rocks at the bottom of the ocean and the rocks of the continent. Which rocks were younger or older? The scientific advance that humanity achieved during the second world war allowed this question to be answered, as it was during this period that "sonar" was created, a device that is able to reveal the ocean floor
From the creation of this device, and other equipment, scientists were able to study the underwater mountains known as oceanic dorsals. During these studies, scientists were able to create methods of donating rocks and were able to conclude that the closer to the oceanic mountains the rocks were, the younger they were. On the other hand, the closer to the continent, the rocks were, the older they were. They will conclude that this must have been influenced by the phenomenon called continental drift, which refers to the movement of the masses of the planet over a period of time.
Because of Earth's axial tilt (obliquity), our planet orbits the Sun on a slant which means different areas of Earth point toward or away from the Sun at different times of the year. Around the June solstice, the North Pole is tilted toward the Sun and the Northern Hemisphere gets more of the Sun's direct rays.
Answer:
Norway
Explanation:
Officially there are three countries that compose Scandinavia, Norway, Sweden, and Denmark. Occasionally, Finland, Iceland, Faeroe Islands, and Aaland Islands are included, but that is only for local usage.
Out of the three countries, the one that has the biggest elevation is Norway, with Sweden coming as second, and Denmark having the lowest elevation. Norway's average elevation is 460 m. Sweden's average elevation is 320 m. Denmark's average elevation is only 34 m, making it the fifth joint lowest country in the world.
Norway has the highest elevation out of the three because the around half of the country is dominated by mountains, while Sweden also has mountains, it is mostly dominated by lowlands, and Denmark is entirely very low, lacking a single mountain or even a higher hill on its territory.
