Identify the biome shown in the photographs above. In a short paragraph, explain at least three of its characteristics.

Answers

Answer:

Hi! The biome in the photo is a jungle/rainforest.

Jungles are very moist, with rain misting almost daily, if not always. Jungles can also be very hot and humid, attracting reptiles to sunbathe, which makes the jungle a dangerous place. Predators of all types roam in the jungle. Leopards, Cobras, Poisonous Frogs, Tigers, Panthers, and more can be found here.

Hope this helped!

Answer:

These photographs show Earth’s rainforest biome. This biome is usually located in areas with tropical climates. Plants in these areas have adapted to survive with large amounts of rain. Animals have adapted to deal with dense forests, large jungles, and a warm climate. The rainforest biome stands out because of its biodiversity. This means that it has a very large number of species, including plants and animals.

A thrust fault increases the thickness of the crust as it moves toward a continental interior in a mountain belt; yet the crust beyond the mountain front stays the same thickness. Isostasy would suggest that the area at the mountain front, where the thrust emerges, should ________ over time.

Answers

Answer:

subside

Explanation:

Isostasy is a geographical term which describes the condition of gravitational equilibrium that exists within the Earth's crust and mantle, there by, making the crust stays above a heights that relies on its physical attributes, such as thickness and density.

In Isostasy, its occurrence process involves principles of buoyancy in which an Earth crust apply stress on the less stronger mantle, such that for over a geological time moves laterally in a way that the load is contained by height adjustments.

Hence, Isostasy would suggest that the area at the mountain front, where the thrust emerges, should SUBSIDE over time.

Look at the Declaration of Independence, and explain why the United States seperated from
England.

Answers

Answer:

Religion.

Explanation:

England was a very religion based country, as it had many historical back and forths from going from a strictly Catholic country, to Protestant. Many people were forced to conform according to whatever the religion was during that time period, and to some people that was not acceptable. A lot of people that were heartfelt Catholics felt it was betraying their religion and condemning their souls by proclaiming not to follow Catholicism anymore. It did not help that the main reason Protesism came into play was all started because King Henry the 8th wanted to marry Anne Boleyn while he was still married to his very Catholic wife, Queen Catharine of Aragon.

When Englanders came to America, it was to escape religious persecutions and to be able to follow whatever religion they chose, without fear of a ruler burning them at the stake for doing so. Hence, religion was a huge part of why U.S. seperated from England.

Do you think the climate of our Earth will remain same after next 30 years? Justify it.​

Answers

Answer:

No it will not stay the same for the next 30 years

Explanation:

We are polluting the planet vey fast and so fast that the planet cannot recover. Just thing of the virus spreading and now spreading so fat that we have no time to cure it .

Answer:

The Earth's climate changes from year to year, summers are warmer, winters are harsher and sometimes snow-free. In desert areas, temperatures are rising, and water resources are insufficient. Human activities greatly destroy the geographical environment: oil accidents, pollution of oceans and seas, large amounts of waste.  

Scientific studies show that the Earth's climate is changing and there is an increase in temperature and even the melting of mountain and cap glaciers.  

In the next 30 years the planet's climate will change depending on the responsibility of humans to protect the planet and maintain a healthy and clean environment.

Porosity increases:_________. a. when grains settle more closely together after deposition.b. with increasing crystallization between grains in sedimentary rock. c. with the cementing of sediments by minerals from groundwater. d. when rocks develop joints or fractures.

Answers

Answer:

The correct solution is Option d (when rocks develop joints or fractures ).

Explanation:

Porosity is observable from descriptive samples taken. The drawbacks of receivable dams are that this is impossible to make true reflection temperature measurements, specific side-wall concrete samples while being often valuable can also result in poor coverage as well as dependence on log-derived porosity seems to have become the standard.As porosity rises, too much wind needs to pass further through most of the shelterbelt, which would be to say the less significant decrease in wind direction.

Some other available scenarios have no connexons with the particular circumstance. So this seems to be a reasonable option.

Lines b and c are parallel. Horizontal and parallel lines b and c are cut by transversal a. Where line b intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: (13 x + 9) degrees, 2, 4, 3. Where line c intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, (5 x + 9) degrees, 8. What is the measure of Angle6?

Answers

Answer:

  54°

Explanation:

We believe the intended angle numbering is as shown below. This means the marked angles are supplementary, so ...

  (13x +9) +(5x +9) = 180

  18x +18 = 180

  x + 1 = 10

  x = 9

Angle 6 is congruent to (5x+9), so has measure ...

  (5(9) +9) = 54 . . . . degrees

Angle 6 is 54 degrees.

Describe how voting changed in America from the early days to the present.

Answers

Hey there! I'm happy to help!

There are many ways that voting has changed in America. When America was founded, only property-owning white males could vote.

During the end of the 18th century to about the mid-1800s the part that you had to own property was removed.

In 1870, the 15th amendment was passed, which allowed males of all races to vote.

In 1920, the 19th amendment gave women the right to vote.

Decades later, the 23rd amendment let residents of Washington D.C. vote.

The 17th amendment also let the people choose who their Senators would be, not the Legislature.

How are catastrophic events related to changes in geological timelines

Answers

They define geological periods because scientists use them as reference points for tracking the history of the earth. They cause significant changes that disrupt the equilibrium of the earth and lead to natural separation points.

Uniformitarianism means:________. a. neither the scientific past nor the future can be predicted because physical laws change over time. b. earth's surface, including the oceans and continents, has always been the same and will always remain unchanged. c. geologic processes on Earth all operate at roughly the same speed, which has not changed over time. d. geologic processes that operate today operated in the past at about the same speed.

Answers

Answer:

Uniformitarianism means:

d. geologic processes that operate today operated in the past at about the same speed.

Geologists study present geologic processes, whether they are sudden, like an earthquake, or slow, like the erosion of a river valley, to gain insight into the past. This is known as uniformitarianism.

Thus, option D is correct.

Who made uniformitarianism?

The theory of uniformitarianism was developed by Charles Lyell in the 19th century and is based on the writings of James Hutton. According to this hypothesis, the forces and processes that can be seen at the surface of the earth are the same ones that have sculpted the planet's terrain throughout natural history.

The belief that the same natural laws and processes that govern the universe today and have always governed it in the past and apply to all of it is known as uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle. Today, we accept uniformitarianism as genuine and understand that major catastrophes like earthquakes, asteroids, volcanoes, and floods are a regular part of the earth's cycle.

Answers

Answer:

O Brasil é rico em minerais como: nióbio, ferro, manganês e alumínio.

Explicação:

Altas reservas de nióbio, ferro, manganês e alumínio estão presentes no Brasil. O nióbio é um metal muito precioso e importante que é usado como ligas porque fornece resistência ao metal em uma temperatura muito baixa. É usado principalmente em foguetes porque a temperatura do espaço é muito baixa, cerca de -270 Celsius, o que é insuportável para o aço, então ele quebra, mas a liga com o nióbio o torna mais difícil nessa baixa temperatura. É por isso que o nióbio é um metal muito caro.
