Geologic history is divided into eras, periods, and epochs based on the changes or events recorded in rocks and fossils.
What is Geologic history?According to the geological time scale, a method of measurement based on the examination of the planet's rock strata, the geological history of Earth follows the main geological events in the planet's past (stratigraphy). The Solar Nebula, a disk-shaped collection of dust and gas left over after the birth of the Sun, which also produced the rest of the Solar System, was the source of Earth's origin around 4.54 billion years ago.
Due to intense volcanism and frequent collisions with other things, the Earth was first molten. When the water started to gather in the atmosphere, the planet's outer layer eventually cooled to create a solid crust. A planetoid's impact on the Earth may have caused the Moon to develop shortly after.

The Arctic Mediterranean Sea is what some oceanographers refer it, however the International Hydrographic Organization (IHO) classifies it as an ocean.
he Atlantic Ocean's estuary has also been used to characterize it. It is also regarded as the northernmost region of the vast World Ocean.
The Arctic Ocean, which reaches south to roughly 60°N, encompasses the area around the North Pole, which lies in the center of the Northern Hemisphere. The borders between Eurasia and North America, which encircle the Arctic Ocean, are determined by topographical features: the Bering Strait on the Pacific side

Answer:
SORRY ITS SO LONG IT TOOK ME AGES
Explanation:
Africa, the second-largest continent, is bounded by the Mediterranean Sea, the Red Sea, the Indian Ocean, and the Atlantic Ocean. It is divided in half almost equally by the Equator. The continent includes the islands of Cape Verde, Madagascar, Mauritius, Seychelles, and Comoros.
Africa’s physical geography, environment and resources, and human geography can be considered separately.
The origin of the name “Africa” is greatly disputed by scholars. Most believe it stems from words used by the Phoenicians, Greeks, and Romans. Important words include the Egyptian word Afru-ika, meaning “Motherland”; the Greek word aphrike, meaning “without cold”; and the Latin word aprica, meaning “sunny.”
Today, Africa is home to more countries than any other continent in the world. These countries are: Morocco, Western Sahara (Morocco), Algeria, Tunisia, Libya, Egypt, Sudan, Chad, Niger, Mali, Mauritania, Senegal, The Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, Côte d’Ivoire, Ghana, Burkina Faso, Togo, Benin, Nigeria, Cameroon, Central Africa Republic, Equatorial Guinea, Gabon, Congo, Democratic Republic of the Congo, Angola, Namibia, Botswana, South Africa, Lesotho, Swaziland, Mozambique, Zimbabwe, Zambia, Malawi, Tanzania, Rwanda, Burundi, Uganda, Kenya, Somalia, Ethiopia, Djibouti, Eritrea and the island countries of Cape Verde, Madagascar, Mauritius, Seychelles, and Comoros.
Cultural Geography
Historic Cultures
The African continent has a unique place in human history. Widely believed to be the “cradle of humankind,” Africa is the only continent with fossil evidence of human beings (Homo sapiens) and their ancestors through each key stage of their evolution. These include the Australopithecines, our earliest ancestors; Homo habilis, our tool-making ancestors; and Homo erectus, a more robust and advanced relative to Homo habilis that was able to walk upright.
These ancestors were the first to develop stone tools, to move out of trees and walk upright, and, most importantly, to explore and migrate. While fossils of Australopithecines and Homo habilis have only been found in Africa, examples of Homo erectus have been found in the Far East, and their tools have been excavated throughout Asia and Europe. This evidence supports the idea that the species of Homo erectus that originated in Africa was the first to successfully migrate and populate the rest of the world.
This human movement, or migration, plays a key role in the cultural landscape of Africa. Geographers are especially interested in migration as it relates to the way goods, services, social and cultural practices, and knowledge are spread throughout the world.
Two other migration patterns, the Bantu Migration and the African slave trade, help define the cultural geography of the continent.
The Bantu Migration was a massive migration of people across Africa about 2,000 years ago. The Bantu Migration is the most important human migration to have occurred since the first human ancestors left Africa more than a million years ago. Lasting for 1,500 years, the Bantu Migration involved the movement of people whose language belonged to the Kongo-Niger language group. The common Kongo-Niger word for human being is bantu.
The Bantu Migration was a southeastern movement. Historians do not agree on why Bantu-speaking people moved away from their homes in West Africa’s Niger Delta Basin. They first moved southeast, through the rain forests of Central Africa. Eventually, they migrated to the savannas of the southeastern and southwestern parts of the continent, including what is today Angola and Zambia.
The Bantu Migration had an enormous impact on Africa’s economic, cultural, and political practices. Bantu migrants introduced many new skills into the communities they interacted with, including sophisticated farming and industry. These skills included growing crops and forging tools and weapons from metal.

Which of the following processes would take the longest to change landforms on the Earth's surface?
A) An earthquake shaking and cracking the ground
B) A volcanic eruption depositing lava
C) Weathering of a rock by wind
D) Landslide down the side of a mountain
hello,
here is your answer:
**********
C. Weathering of a rock by wind
This process would take the longest time because it is a slow process while the rest are quick.
**********
hope this helped,
:)
This process would take the longest since it moves slowly while the others do so quickly. Hence option C is correct .
What is Weathering ?Weathering, erosion, and deposition typically take years to produce observable changes. However, other events alter the surface of the Earth far more swiftly. These include landslides, earthquakes, and volcanic outbursts.
Landforms are generated, modified, or destroyed as several types of crust intersect. Dramatic occurrences like earthquakes and volcanic eruptions can also be caused by these encounters. In contrast to this activity, changes in landforms typically take hundreds or even millions of years.
The breakdown or dissolution of rocks and minerals on the Earth's surface is referred to as weathering. Agents of weathering include water, ice, acids, salts, plants, animals, and variations in temperature. When a rock is broken down, a process known as erosion removes the rock and mineral fragments.

What do you think is Population Density? How does population density affect global warming?
Answer:
Per-capita greenhouse gas emissions may drop,
Explanation:
Per-capita greenhouse gas emissions may drop, but the population bulge will continue to contribute to a dangerous increase in greenhouse gases in the atmosphere. Time is short, but it not too late to stop runaway global warming.
Answer:
Population density allows for broad comparison of settlement intensity across geographic areas. When comparing population density values for different geographic areas, then, it is helpful to keep in mind that the values are most useful for small areas, such as neighborhoods. For larger areas (especially at the state or country scale), overall population density values are less likely to provide a meaningful measure of the density levels at which people actually live, but can be useful for comparing settlement intensity across geographies of similar scale.

Answer:
This is a convergent plate boundary. Two tectonic plates push into each other, leading to the bottom of the plate being pushed back into magma under the plates. This movement creates mountains and valleys.
In the diagram mentioned above, states about the convergent plate boundary.
What is convergent plate?A convergent border occurs when two plates come together. The impact of colliding plates can cause one or both plates' edges to bow up into mountain ranges, or one plate to bend down into a deep undersea trench.
Subduction is the process through which one plate moves beneath the other. The Wadati-Benioff zone, a plane where frequent earthquakes occur, defines the subduction zone.
This is a plate border that has converged. When two tectonic plates collide, the bottom of the plate is forced back into magma under the plates. Mountains and valleys are formed as a result of this movement. Therefore, The convergent plate boundary is seen in the diagram above.
