Imagine that you are a member of a team of scientists who are drilling into a large crater approximately 200 km wide. The crater was formed by an NEO impact that wiped out many species 251 million years ago. The drilling team will recover rock samples during the drilling process. You have some data to suggest that the crater is located between 500 and 1,500 meters below the surface. How will the drilling team know when the drill reaches the crater

Answers

Answer 1

Answer:

Explanation:

The team will obviously known that they have reach the crater because during impact the rock would have ungergone contact melting of the rock. However, the rock maybe composed of angular fragments in a matrix that may be similar or a different material underneath the crater. Suppose the scientist drilling further down the surface, there will be presence of little or no impact. But inside the crater there will be fragments of broken rocks. They will observe the shocked minerals and the drill will eventually located the undisturbed sequence of rocks at the crater floor.

Answer:

A population

Explanation:

The rate of natural increase of a population depends on birth and death rates, which are strongly influenced by the population age structure. Births occur primarily to people in the younger-adult age groups. If there are comparatively more young adults than older adults where mortality is highest, then even at replacement fertility levels (when each woman has about an average of two children) there will be more births than deaths.

In hot deserts we also find plateau land– ________________ with flat tops.

Answers

Answer:

landscape or landform with flat top.

Explanation:

A desert is a barren landscape that consists of very little rainfall. Lack of vegetation and unprotected surface makes the soil weak and prone to erosion. They cover one-third of the surface of the earth and have a semi-arid type of climate.  A plateau consists of a flat elevated landform that rises sharply above the surrounding area. Soft rocks are often eroded at the top of a plateau. The caprocks protect its surface from erosion.

Answers

Answer:

African slaves were brought in the area to work on sugarcane plantations

Hello. You forgot to say that this question refers to the northeast of Brazil.

The influence of African culture in northeastern Brazil was due to the large number of African slaves who were taken to this region to work hard in the sugar cane plantations. These slaves were taken to Brazil by the Portuguese, who colonized the place. Most of the slaves were concentrated in the northeastern region, the one with the most elements of African culture.

What stage of genocide is "Population distinguished between Ottoman Turks (Muslim) and Armenians (non-Muslim, Christians). "

Answers

Answer:

This happened in the first stage of genocide.

Explanation:

The Turkish government has made up its mind to make the country homogoenous when it comes to ethnicity and religion. This meant that everyone in Turkey should be Turkish by ethnicity and Sunni Muslim by religion. One ethnic group in particular though was a thorn in the eyes of the Turkish government, that being the Armenians.

In order to start a process of genocide, they played tactically an step by step. What they did first was to set a clear distinction on the ethnic and religious base between the Muslim Ottoman Turks on one side, and Christian Armenians on the other side. This was done because it opens up the gates for divisio between the populations which makes it easier to convince people to later act aggressivelly when they don't feel any connection to the other group.

Answers

Answer:

The correct answer is C. 2, 4, 1, 3.

Explanation:

The Middle East is a region that has had big problems for quite some time now. The problems mainly have occurred because of political and religious reasons. It is something that has started with the crumbling of the Ottoman Empire and continues to this day.

The Middle East, in big portion, got under the rule of the Western powers. That didn't last long, but the rulers, before granting independence to the countries of the region created and implemented borders in accordance with their interests, leading to the partitioning of the Middle East and creating long-term problems. The tensions and problems just increased when after World War II, the Jewish people were granted Israel as a piece of land to form their own country. This led to several wars in the region and a lot of hatred. The dictators and terrorist organizations didn't help the region with their activities too, giving a reason to foreign countries to attack them, overthrow them, and create even bigger chaos, as was the war in Iraq. Last but not least, the people have had enough of their oppressive rulers and tried to take them down so that democratic societies can be organized, which also led to a lot of violence and chaos.
