b. the atmosphere and hydrosphere
c. the geosphere and hydrosphere
d. the geosphere, hydrosphere, and atmosphere
D) The geosphere, hydrosphere, and atmosphere
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
The carbon cycle is the biogeochemical cycle which involves an exchange of carbon among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Carbon is the most important component of the biological compounds such as limestone. Also, during soil respiration, Carbon can leave the soil through it which releases , which carries it into the rivers or the ocean, where it then enters the hydrosphere.
Thus, option D is correct.
The two factors that affect the magnitude of the force are magnitude of force and distance of line of action of force.
Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
