" which graph best represents the percentage by mass of elements of earth's crust " ?
Answers
Answer: Graph 1
Explanation:
The Earth’s crust has minerals that are made up of different elements, most of them combined in compounds. Of those elements, oxygen takes 46.1% of the total mass, while there´s 28.2% of silicon and the other 25.7% includes the rest of the elements, which are aluminum, iron, calcium, sodium, potassium, magnesium, copper, uranium, gold, and silver.
The elements of the earth's crust are oxygen, silicon, iron, and aluminum that accounts for about 88% of the earth's crust and the remaining 90 elements make up 12% of the earth's crust.
Oxygen hare the largest mass of these elements. The O2 elements are 46%, silicon 28.2%, and others 25% hence the option one is correct.Learn more about the represents the percentage by mass.

Tectonic plates move because they are slowly expanding and growing larger.
What is tectonic plates?An enormous, unevenly shaped slab of solid rock known as a tectonic plate also known as a lithospheric plate is typically made up of both continental and oceanic lithosphere.The Pacific and Antarctic Plates are among the largest, however plate sizes can range from a few hundred to thousands of kilometers broad.The Earth's crust and uppermost mantle are divided into enormous fragments called tectonic plates. Oceanic and continental crust both make up their structure.Mid-ocean ridges, as well as the significant faults that delineate the boundaries of the plates, are subject to earthquake activity.Tectonic plates move because they are slowly expanding and growing larger.To learn more about Tectonic plates refer to:

Which demographic indicator would best align with high educational attainment in a more developed country?
Answers
Answer:
Demographic indicators of income status.
Explanation:
The education attainment of the nation such as developing or developed ca be seen in terms of higher standards of living and describes the schooling, along with the teachers and students. A higher-income status would best indicate the level of education as many countries don't have money to continue for higher studies. Thus are unable to take higher education and are school dropouts.What is shown in this illustration?
continental-continental convergence boundary
oceanic-oceanic convergence boundary
divergent boundary
transform boundary
Answers
Answer:
The answer is B. Oceanic-Oceanic convergence boundary
I took the test and got it right. Good luck!
Oceanic-oceanic convergence boundary is shown in this illustration. Option B is an appropriate response.
What is Oceanic-oceanic convergence ?Two oceanic plates converge or clash during ocean-ocean convergence. Under the convergence zone, the denser plate subducts into the asthenosphere, creating a trench on the surface. The zone of subduction is the area beneath the convergence zone.
Examples of ocean-ocean convergence zones are the Aleutian Islands, which were formed when the Pacific Plate was subducted beneath Alaska, and the Marianas Trench, the deepest portion of the ocean, which was formed when the Philippine Plate was subducted beneath it.
Two oceanic lithosphere-based plates colliding is referred to as an oceanic-oceanic convergent boundary. One of the plates will subduct beneath the other even if this boundary comprises the same kind of lithosphere.
Hence, Option B Oceanic-oceanic convergence is an appropriate response.

Answers
Answer:
B. Central America
Explanation: Central America is made up mostly of islands.
According to figures by Territorio Indigena & Gobernanza, there are 375 indigenous peoples in the Amazon of Peru, Ecuador, Colombia, and Brazil Hence option C is correct.
What are Isolated Indigenous ?which at least 71 are living in voluntary isolation, have a deep understanding of nature, and continue to live in a self-sufficient manner.
The indigenous people of the world, particularly those in the Americas, have experienced significant losses over the last few centuries. This was brought on through genocides, forced assimilation, forced marriages, and colonization. Some indigent individuals have had more luck than others, and they have continued to exist in this way up until the present.
The Amazon is home to the bulk of these tribes in the Americas. The rationale is straightforward: It is a vast territory that provides everything they require for but prevents modern civilisation from influencing and gaining access to them. There are thought to be 350 indigenous groups in this region, while there is a strong possibility that there are more given the small populations in question and how difficult it is to locate or get in touch with them.

Without gravity, our universe would not exist. All things have gravitational pulls, but the larger the object, the larger the pull. This explains why planets and other celestial bodies are greatly affected by gravity. Think about ways our planet and the solar system are affected by gravity.
Pick all that apply
Moons' orbits around planets
Annual amounts of snow on Earth
The moon has less gravitational force than Earth because it is smaller and has less mass.
The orbit of each planet in the solar system is controlled by its moon(s).
Mass is the force that holds people and objects to the Earth's surface.
The Sun's gravitational pull is what keeps the planets in its solar system in orbit.
The Sun has more gravitational pull than any planet in the solar system because it has the most mass.
The smaller the distance between two objects, the larger the force of gravity between them
Answers
Answer:
The Sun's gravitational pull is what keeps the planets in its solar system in orbit.
Explanation:
because every planet must orbit the sun and others.
Answer:
Statements that are correct are: moons' orbits around planets, the moon has less gravitational force than Earth because it is smaller and has less mass, the Sun's gravitational pull is what keeps the planets in its solar system in orbit, the Sun has more gravitational pull than any planet in the solar system because it has the most mass, the smaller the distance between two objects, the larger the force of gravity between them.
Explanation:
Option 1: is correct because all moons are orbiting around planets because the planets are the closest objects that are also larger are influence them the most.
Option 2: is not correct because the snowfall on Earth has much more to do with the conditions on the planet than it has with the orbit.
Option 3: is correct because the moon is much smaller than Earth, and its mass is even smaller proportionally, thus its gravitational force is much smaller.
Option 4: is not correct because the moons don't control the orbits of the planets, but the other way around.
Option 5: is not correct because gravity is the force that keeps people and objects to Earth's surface.
Option 6: is correct because the Sun is the object with the most mass and gravitational pull in the solar system, thus it has a big effect on all objects in it.
Option 7: is correct because the Sun is by far the biggest objects in the solar system, and it also has by far the biggest mass, thus its gravitational pull is incomparably bigger than any other object in the solar system.
Option 8: is correct because the closer the objects are the stronger the gravitational pull between them, and the further away they are the weaker the gravitational pull between them.

If you were analyzing a population pyramid, which age and gender would be most
affected if there was a war?
Help!!!!
Answers
Answer:
The age between 18 and 35 of the male population would be the most affected if there was a war.
Explanation:
In a scenario where there is a war, the population that will be affected (negatively) the most will be the male one. In the case of war, in almost all countries in the world, it is the male population that is mobilized, while the female population is not (except in North Korea for example). In general, it is the male population between the ages of 18 and 35 that is mobilized, as this is considered the best age for it.
The male population of this age will have a very negative effect, or rather its numbers will drop in the total population. This will happen because there will be a lot of soldiers that will lose their lives on the fronts, doesn't matter will the war be won or lost. This will also have a negative impact on the female population of the same age group because a lot of them will remain without their husbands or partners, there also will be a lack of males for creating families.
