When dead plants decompose and nitrogen is returned to the soil, the interaction is between which two spheres? A. biosphere and atmosphere

B.geosphere and atmosphere

C. atmosphere and geosphere

D. biosphere and geosphere


Answer 1

When nitrogen is return to the soil from decomposing plant matter, the interaction is between the D. biosphere and the geosphere.

The biosphere comprises all living things in the planet. Plants are living things and when they die and get decomposed, the nitrogen in them leaves the biosphere because the plants are dead.

The nitrogen goes to the geosphere which comprises of:

  • rocks
  • minerals
  • fossilized animal matter

Because the nitrogen goes to the soil which is made up of rocks, we can conclude that it goes to the geosphere which means that the interaction described in the question is definitely between the geosphere and biosphere.

D. biosphere and geosphere


Biosphere is the sum of all the ecosystem. The biosphere house all the living things . The biosphere is composed of recycling of matter and the abundant of various factors like sunlight and oxygen that can keep life . Water is another major factor that contribute to life existence. Other elements like phosphorus , nitrogen, oxygen and hydrogen contributes to the building block of life in the form of carbohydrate, fats , protein and lipids.

The geosphere compose of the lithosphere, hydrosphere and the atmosphere and this is strictly the lifeless earth.

The interaction whereby dead plant(biosphere) decompose to add nitrogen to the soil (Geosphere) is an interaction between biosphere and geosphere.

3.What is significant about the tropic of cancer and Tropic of capricorn?


These two "Tropics" are in fact two parallels, that is, circumferences belonging to Earths theoretical sphere surface, and parallel to the equator. They are the curves on which, on the solstice days, the Sun rays hit the Earth's surface perpendicular to it, along with Earth's rotation. Cancer Tropic is located at the North Emisphere, while Capricorn Tropic is on the South Emisphere. They are both at an angular distance of about 23°26' from the equator.

These two curves (circumferences, actually parallels) are the furthermost points from the equator where the Sun rays would ever reach the Earth's surface in a perpendicular way. For higher or lower latitudes (higher values of latitude's absolute value, be it towards the North or the South poles), Sun rays shall always reach Earth's surface obliquely, that is, by an angle lower than 90 degrees.

These two phenomena occur on:

  • December 21st (starting Capricorn period), northern winter, southern summer.
  • June 21st (starting Cancer period), northern summer, southern winter.

The geographic surface between these two Tropics are called, in fact, the tropical areas, where seasons are not perceived and the Sun can be seen right above our heads (that is, at an elevation angle of 90°) at two specific moments within the year period (depending on the specific latitude).

This all phenomenom is caused by the tilt of the Earth's rotational axis with respect to its traslation plane around the Sun, which causes the existence of two solctices and to equinox every year.


Which two continents are part of one huge land mass, separated by a chain of mountains?


Europe and Asia parts of one huge land mass and they are separated by a chain of mountains. Asia and Europe also share one mass of land. They are also joined in a one large land mass. Europe is a continent and it is the western part of Eurasia. Asia is also a continent, not only a continent but the largest and most populous continent. They are separated by the Ural Mountains in Russia and the Bosporus Strait in Turkey.

What is one reason why many geologists did not at first accept the theory of continenal drift ?



The Continental drift is the displacement of continental masses relative to each other. This hypothesis was developed in 1912 by Alfred Wegener, who affirmed that thousands of years ago there was a single and unique supercontinent, called Pangea, which later became separated.

His formulations were based mainly on the way in which the forms of the continents seem to fit on each side of the Atlantic Ocean, such as Africa and South America. He also took into account the distribution of certain fossils that coincided in continents far from each other.

At first this approach was discarded by most of his colleagues, because his theory lacked a logical and geological explanation for its epoch.

He proposed that the continents move on another denser layer of the Earth that made up the ocean floor. But it was not until the 1960s, with the development of the theory of tectonic plates, that the movement of the continents could be adequately explained.


Because Alfred Wegener was unable to explain the mechanism behind the drifting of the continents


Alfred Wegener was the first person to discover the concept of continental drift. He proposed various evidences in support of the continental drift theory. This includes the following-

  • presence of similar fossil assemblages in different distant continents.
  • matching of the continental margins
  • presence of similar rock sequences, in the continental edges

But the main mechanism behind the continental motion was not explained by him. So, most of the geologists did not accept the continental drift theory.

Later, with the modification, the plate tectonic theory was developed that provided the main mechanism for the plate mechanism. The main mechanism here is the convection current that forms in the mantle.

How many time zones does earth have?


If you count only the time zones which are in the intervals of full hour, it's 24, but the actual number of the different time zones on Earth is 40. Many time Zones are not full hours separated from other time zones, for example, India is in the time zone of UTC+5hrs 30 mins and Nepal is its own time zone: UTC+5hrs 45 mins

Which civilization calculated the movement of the planets? Answer Aztec Maya both a and b none of the above


The correct answer is B. Maya

Mayans had calculated the movement of the planets and moon phases because they believed that planets were gods. That is why they crowned their kings on nights when planets were clearly visible on the sky.

And thus for a time I was occupied by exploded systems, mingling, like an unadept, a thousand contradictory theories and floundering desperately in a very slough of multifarious knowledge, guided by an ardent imagination and childish reasoning, till an accident again changed the current of my ideas. When I was about fifteen years old we had retired to our house near Belrive, when we witnessed a most violent and terrible thunderstorm. It advanced from behind the mountains of Jura, and the thunder burst at once with frightful loudness from various quarters of the heavens. I remained, while the storm lasted, watching its progress with curiosity and delight. As I stood at the door, on a sudden I beheld a stream of fire issue from an old and beautiful oak which stood about twenty yards from our house; and so soon as the dazzling light vanished, the oak had disappeared, and nothing remained but a blasted stump. When we visited it the next morning, we found the tree shattered in a singular manner. It was not splintered by the shock, but entirely reduced to thin ribbons of wood. I never beheld anything so utterly destroyed. Before this I was not unacquainted with the more obvious laws of electricity. On this occasion a man of great research in natural philosophy was with us, and excited by this catastrophe, he entered on the explanation of a theory which he had formed on the subject of electricity and galvanism, which was at once new and astonishing to me. All that he said threw greatly into the shade Cornelius Agrippa, Albertus Magnus, and Paracelsus, the lords of my imagination; but by some fatality the overthrow of these men disinclined me to pursue my accustomed studies. It seemed to me as if nothing would or could ever be known. All that had so long engaged my attention suddenly grew despicable. By one of those caprices of the mind which we are perhaps most subject to in early youth, I at once gave up my former occupations, set down natural history and all its progeny as a deformed and abortive creation, and entertained the greatest disdain for a would-be science which could never even step within the threshold of real knowledge. In this mood of mind I betook myself to the mathematics and the branches of study appertaining to that science as being built upon secure foundations, and so worthy of my consideration.

Readers can see the events from more than one perspective. Readers cannot form an opinion without Victor's interpretation. Readers see little to suggest Victor is guilty of any crime.
