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:
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:
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?
What two conditions must exist for an artesian well to form?
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-
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.
