ASAP plz Which statement best describes how the Great Rift Valley in Africa formed?

The rift valley formed when the crust pulled apart.
The rift valley formed due to subduction.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary

Answers

Answer:

The rift valley formed when the crust pulled apart.

Explanation:

The Great Rift Valley in Africa is a rift valley that stretches across the eastern part of the continent, though regionally it passes through Eastern, Central, and South Africa. It is the longest rift valley in the world, and it is constantly becoming wider and wider. To not be confused, this rift valley is not just one line cutting through the continent, but it has divisions that are connected to it.

The reason for the formation of the Great Rift Valley is the divergent boundary that has formed in this part. This divergent boundary has cracked open the crust of the African plate, now dividing it into two separate plates, the Nubian plate, and the Somali plate. Now, these two plates are moving away from each other, and over time, as the gap between them grows, the seawater will fill in the space between them, physically separate them, and give rise to a new sea which will later become an ocean.

Answer:

A) The rift valley formed when the crust pulled apart.

Explanation:

Today, the term is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward across eastern Africa, and is in the process of splitting the African Plate into two new separate plates.

Pablo wants to know the stage of the democratic transition model that his grandparents’ home country is currently at. The mortality rate has been slowly declining for a couple of decades. The fertility rate is still higher than in the most developed countries, but it is beginning to decline as well. What stage would this represent?

Stage 1

Stage 2

Stage 3

Stage 4

Answers

Answer:

Pablo's grandparents' home country is in Stage 3 of the demographic transition model.

Explanation:

Stage 1; is not correct because in this stage the mortality rates are very high, and the fertility rates are also very high.

Stage 2: is not correct because in this stage the mortality rates are still relatively high, while the fertility rate is the highest.

Stage 3: is correct because in this stage the mortality rate is at a medium level, thus declining, while the fertility rates have declined but are still on a good level.

Stage 4: is not correct because in this stage the mortality rate and the fertility rate are both relatively low, they equalize at the end of this stage, and the population stagnates or has just a very small growth.

Which of the following is true of the Antarctic Treaty System?
A. It allows limited weapons testing of the continent.
B. It limits restrictions of environmental controls.
C. It encourages scientific research.
D. Members came from the Antarctic Agreement.

Answers

Answer:

The Antarctic Treaty System encourages scientific research.

Explanation:

The Antarctic Treaty has been put in place in order to prevent escalation of the situation during the past century, but also to prohibit any violence and military interventions in the continent. Numerous countries rushed to take their piece of Antarctica with the goal of taking as much as possible for further exploitation. This led to a lot of tensions, so luckily all sides set at a table and solved the problems in a diplomatic manner.

There are a lot of articles in the treaty, but one of the most important ones is the one that focuses on science. This treaty supports scientific research and encourages the countries to do so. Not just that, but it encourages collaboration between the countries in their scientific teams in order for them to get closer and to work for mutual and global interest.

Which of these descriptions most likely represents a human community with
the highest birthrates?
A. Low economic status, more access to technology
B. High economic status, more access to technology
C. Low population density, less access to technology
D. High population density, low economic status

Answers

Answer:

A human community with high population density and low economic status will have the highest birthrates.

Explanation:

A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.

B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.

C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.

D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.

D

Answers

Answer:

Number one is Mexico

The name of the country labelled with the number 1 on the map above is Mexico.

What is the prehistory of Mexico?

The prehistory of Mexico stretches back millennia. The earliest human artefacts in Mexico are chips of stone tools found near campfire remains in the Valley of Mexico and radiocarbon-dated to circa 10,000 years ago.

Mexico is the site of the domestication of maize, tomato, and beans, which produced an agricultural surplus. This enabled the transition from paleo-Indian hunter-gatherers to sedentary agricultural villages beginning around 5000 BCE. In the subsequent formative eras, maize cultivation and cultural traits such as a mythological and religious complex, and a vigesimal numeric system, were diffused from the Mexican cultures to the rest of the Mesoamerican culture area. In this period, villages became denser in terms of population, becoming socially stratified with an artisan class, and developing into chiefdoms.

The most powerful rulers had religious and political power, organizing the construction of large ceremonial centres.
