Answer:

As principais formas desenvolvidas pelos seres humanos para se orientar e observar o espaço foram a bússola, a rosa dos ventos e o GPS.

Explanation:

Antes de explicar a sua eprgunta, eu preciso te falar que esse não é osite brasileiro e sim o americano, por esse motivo ele esta todo em inglês. Isso significa que para postar pergunta em português nesse site, você deve postar essa pergunta no campo "World Languagens", independente da materia que essa pergunta é, caso contrario, a sua pergunta pode ser apagada sem receber resposta.

Os seres humanos precisavam criar sistemas que permitissem que eles se orientassem a cerca do espaço ao seu redor e podesse, assim, se locomover para qualquer região que quisessem.

Dentre esses sistemas, a rosa dos ventos e a bússola foram essenciais não só para a locomoção, mas para a evolução das sociedades, ja que isso permitiu que os navegadores e exploradores tivessem contato com outras regiões e outros povos.

Atualmente o GPS é a criação mais eficiente, podendo orientar os individuos com precisão, a cerca do espaço onde estão localizados.

Answer:

e. is produced by the absorption of UV radiation.

Explanation:

The thermosphere is a layer of Earth's atmosphere which is directly above the mesosphere and below the exosphere. It extends from about 85 to 500 km altitude above the earth.

In the thermosphere, the temperature is strongly dependent on the level of solar activity. When the Sun is very active and emitting more high energy radiation, the thermosphere becomes hotter by X-ray and UV radiation absorption.

Answer:

The soil structure and soil salinity are the main agents, controlling the distribution of mangroves. Along the Indian coast and major groups of islands, large variations exist in the soil of mangrove forests.

Answer:

The lenght of one leg is 22 units

Explanation:

Given

[tex]h = 22\sqrt 2[/tex] --- hypotenuse

Required

The length of one side (l)

In a 45-45-90 triangle, the two sides are equal; i.e.

[tex]x^2 + y^2 = h^2[/tex]

Where:

[tex]x = y[/tex] --- the legs of the triangle

So, we have:

[tex]x^2 + x^2 = (22\sqrt{2})^2[/tex]

[tex]2x^2 = (22\sqrt{2})^2[/tex]

This gives:

[tex]2x^2 = 968[/tex]

Divide both sides by 2

[tex]x^2 = 484[/tex]

Take square roots of both sides

[tex]x = \sqrt{484}[/tex]

[tex]x=22[/tex]

Answer: You must be in the path of totality.

Explanation:

It is a thin ribbon of area.

Answer:

Only viewers located in the path of the Moon's full shadow, its umbra, can see a total solar eclipse. Those outside the path see a partial eclipse. By convention, therefore, eclipses are named after their darkest phase—if a solar eclipse is total at any point on Earth, it is called a total solar eclipse.

Answer:

No.

Explanation:

No, 6x - 3 has not 3 terms but 2 terms. In algebra, + and - signs separate two terms from one another not multiplication. In the equation, we can see that there is two terms that is separated by one + sign.  3x + 4y -z, 5xy + 4yz + 4 ,a + b –c are the examples of an equation having three terms and also called trinomial whereas the 6x - 3 is binomial because it has two terms.

Answer:

I believe it is 50 ft

Explanation:

Each line going to the top of the hills are contour lines. If we use the contour lines going to the thick line labeled 250, we can assume that each sub line below it is 50 ft.

Answer:

Vegetation can affect climate and weather patterns due to the release of water vapor during photosynthesis. The release of vapor into the air alters the surface energy fluxes and leads to potential cloud formation.

Answer:

Las principales diferencias entre el lado este y el lado oeste de América son del tipo geográfico e histórico, lo cual a su vez influye en los factores culturales de la región.

Así, el este de la nación es la región más antigua del país, y a su vez la más poblada, en tanto la mayor parte de las ciudades más pobladas del país (como Miami, Nueva York, Filadelfia y Washington, entre otras) se encuentran allí. Culturalmente, es una zona más conservadora y con mayores influencias británicas y europeas.

En cambio, el oeste de los Estados Unidos tiene una cultura mucho más diversa, con gran influencia latina, y un clima mucho más árido que el del oeste.

grid plan

Explanation:

In simple words, The grid plan, also known as the grid street design or stadium design, is a sort of city layout in which routes travel at perpendicular to one another to create a grid. The cost of infrastructure is often higher for regular grid layouts than for layouts with disconnected streets.

These plans are highly evident as they started right from the ancient france and Spain.

-Pangaea broke and spread apart

-continents were once one land mass

Plate Tectonics

-Landforms result from moving plates

-plates move and interact

-Lithosphere is made of large pieces

Answer:

D

Explanation:

D layer is the last layer of the soil that is present at the bottom of other layers having the oldest layers. The bottom layer of soil is formed first and when we go up the age of soil layers decreases because it is formed after the parent soil. The fossil that is present at the bottom layer is considered as oldest fossil as compared to those fossils that are present in the above layers of that soil.

The crust is the outermost layer of the earth that is composed of rocks. The oldest fossil is found in the D layer of the cross-section.

Fossil is the dead remains of the plants and animals buried in the layers of the crust of the earth. The rock layers of the crust contain fossils from various eras.

The deep layer or the last layer was formed first hence, will contain the oldest fossil as the age of the rock and soil decreases when one moves upward towards the surface.

Therefore, option d. the D layer is the parent layer and will have the oldest fossil.

Answer:

Magma forms when any type of rock is melted, a process driven by energy from Earth's interior. The plate motion that occurred near the Great Plains and Rocky Mountains uplifted igneous rock that formed underground. This rock eventually eroded and its sediment formed sedimentary rock in the Great Plains.

Crystal growth, elastic deformation, and sediment load are the 3 stages that turn one rock into another. By undergoing one or more of these transformations, every rock can become any other rock. The rock cycle is the result of this.

Rising magma to the surface of the Earth, where it heats up and develops into igneous rock, like during a massive eruption. Soil erosion breaks down rock formations on the ground into gravel, dust, and clay, forming sediment that collects in valleys on the Planet's surface.

The material near the bottom is squeezed, hardened, and becomes rock type as subsequent layers of material descend on top of each other.

Wind erosion can break down sandstone and shale back into the sand. It could also result in the creation of a different sort of rock. It may turn into rock formations if it is buried deep enough inside the crust to be exposed to increased warmth and pressure.

Metamorphic rock can be changed from igneous rock, and metamorphic rock exposed to the Earth's surface can be eroded to produce sediment. Furthermore, metamorphic and sedimentary materials forced far down by subsidence may melt to generate magma and then cool to become igneous rock.
