Answer:
Photosynthetic organisms began to reduce carbon dioxide and photosynthetic organisms began to produce oxygen.
Explanation:
Earth's early atmosphere was much different than the one we know of today. It was a type of atmosphere that did not provide conditions for larger life forms to develop, but this all change thanks to the first microorganisms on the planet. Even though extremely small, the cyanobacteria spread out across the planet and dominated it, but what's more important is that it used the process of photosynthesis, which changed Earth's atmosphere forever.
The cyanobacteria, in order to perform the process of photosynthesis, needed carbon dioxide, so it was obtaining it from the atmosphere. Once used for its purposes, the cyanobacteria were releasing the oxygen of the carbon dioxide back into the atmosphere. This resulted in a reduction of the carbon dioxide levels and an increase in the oxygen levels in the atmosphere, so over the course of a very long period of time the atmosphere changed drastically, and it provided conditions for other, larger organisms to start developing.
jobs focused on providing services are part of the ______ economic sector
Answer:
Jobs focused on providing services are part of the tertiary economic sector.
Explanation:
There are four economic sectors based on the activities that are performed by the people. The primary economic sector, secondary economic sector, tertiary economic sector, and quaternary economic sector are the four economic sectors, all of which have their own unique characterisitcs. The tertiary economic sector is characterized by providing services.
ng serIn this economic sector, the jobs focus on providing services for the customers, and this is a sector that tends to be dominant in the countries that are well developed or the countries that have no other choices than to get engaged in it in order to have income. The well-developed countries are dominated by this sector because in the primary and secondary ones they don't need much labor force because of the advancements in technology, plus this sector is highly profitable. The countries that depend almost exclusively on tourism for income, like the big portion of the island nations at and around the tropics, have almost all of their labor force engaged in tourismm thus providing services for the tourist.

What is the sum of the degrees of the interior angle of a 19-gon
Answer:
3060°
Explanation:
If a body is made up of 19 sides we can find sum of the interior angles using the relationship below;
Sum of interior angles = (n-2) x 180
n = number of sides = 19
So, the sum of interior angles;
Sum of interior angles = (19 -2) x 180
Sum of interior angles = 17 x 180 = 3060°

What are the social, economic and environmental benefits of a sea wall? brainliest for best answer
Answer:
While past studies had focused on examining how sea walls and armoring affect changes in habitat and species distribution, this model also takes into account nutrient cycling, connectivity, productivity and trophic structure. The team found that shoreline armoring negatively effects every single one of these categories.
Explanation:
Sea levels are rising and as a consequence so are the number of sea walls. However, until now the environmental impacts of sea walls and other engineering “armoring” have been inadequately studied. A team of scientists from UC Santa Barbara and the National Science Foundation's Long-Term Ecological Research (LTER) network recently collaborated to publish a study in the journal Estuaries and Coasts that analyzes a broad range of environmental effects from shoreline armoring in soft marine sediments, shedding light how such infrastructure is changing more than just landscapes.

What can be assumed about the layers in areas 2 and 4?
The layers formed from sand dunes.
The layers were originally horizontal.
The layers formed in a marine environment.
The layers were deposited in a river bed.
Answer:
The layers were originally horizontal.
Explanation:
We will be correct to say that both layers 2 and 4 were originally horizontal.
As with all sedimentary beds, they are originally laid horizontally in their basin of deposition.
They both now occur in a folded structure. The fold is an anticline and it youngs upward. Layer 2 is older than 4At the time of deposition, we can know the geometry of the beds by the principle of original horizontality. Which suggests that beds are originally laid down flat in a basin.Answer:

There are two numbers. One number is twice the other number. The difference of the smaller number and half the larger number is 20. An equation created to find the smaller number will have .
Answer:
There will be no solution for the question.
Explanation:
Assume;
Smaller number = x
Larger number = y
So,
2x = y
and
x - y/2 = 20
So,
y = 2x
x - y/2 = 20
If we put y = 2x
x - x = 20
There will be no solution for the question.
Answer:
no solution

What problems did the construction of the Aswan High Dam create for the people of Egypt and their environment?
Answer:
this is the possible answer;
Explanation: The Aswan High Dam in Egypt has had some negative consequences for the people and the environment. Hundreds of thousands of people were forced to move. Silt, which has increased the fertility of farmland in Egypt for thousands of years, is no longer carried downriver. Without the silt, the use of chemical fertilizers has risen, increasing pollution. In addition, the Nile River Delta ecosystem has been damaged from the lack of silt and increased pollution.

What is sustainability?Sustainability is commonly described as having three dimensions, environmental, economic, and social. Many publications state that the environmental dimension, and, in everyday use, sustainability are often focused on countering major environmental problems, such as climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. The concept of sustainability can be used to guide decisions at the global, national, and individual levels.
A closely related concept is that of sustainable development, and the terms are often used synonymously. However, UNESCO distinguishes the two thus: Sustainability is often thought of as a long-term goal, while sustainable development refers to the many processes and pathways to achieve it. The concept of sustainability has been criticized for various reasons.
One such criticism is that the concept is vague and merely a buzzword.

1 point
a. lithosphere
b. mesosphere
c. asthenosphere
d. none of the above
Answer:
D none of the above
Explanation:
Answer:
c. asthenosphere
Explanation:
Among the choices above, "asthenosphere" is considered to be the softest or least rigid of all. Its softness is often described as "plastic" because of its ability to bend or having high ductility. The temperature and pressure here is higher compared to the rigid lithosphere, thus most of the rocks reaching this point are melted.
