why is it difficult to determine the carrying capacity of the earth?

Understanding Carrying Capacity There are limits to the life-sustaining resources earth can provide us. ... However, it is very difficult for ecologists to calculate human carrying capacity. Humans are a complex species. We do not reproduce, consume resources, and interact with our living environment uniformly.

Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.

In other words, it's the amount of weight your tire can support safely. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car's maximum load carrying capacity.

A: On earth, we use scales to measure mass and weight; we can use spring scales or hydraulic scales, to name a few. Because we're on earth, an object with 100 kg mass is said to weigh 100kg.

Between its size, composition and the distribution of its matter, the Earth has a mass of 5.9736×1024 kg (5.9 trillion trillion kilograms) or 1.31668×1025 lbs (13 billion trillion tons).

Water is a renewable resource. The amount of water on Earth will always remain the same. We can't run out of water because water continuously works its way through water cycle.

The gravitational acceleration is the same (average 9.81 m s^-2) around the world because it depends on the mass of the Earth and the distance from the centre of the Earth. (How cool is that?!) It doesn't depend on the mass of the object being dropped.

Mass as we measure it today is a comparative gravity of the earth between the standard unit and the object being measured. Because gravity changes with the size and structure of the object, there is no way to determine the absolute value for the mass of an object.

Because Earth is almost spherical, you can calculate its volume (V) using the mathematical relationship V = 4/3 pi x r^3, where "r" is its radius.

The gravitational force exerted on an object near the earth's surface is called the object's weight.

The total mass of Earth's atmosphere is about 5.5 quadrillion tons, or roughly one millionth of Earth's mass.

Fortunately for us, Earth's gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth's size and around one-tenth Earth's mass. Less mass means less gravitational pull. ... The higher you go in the atmosphere, the thinner the air becomes.

The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.

At present, the Earth receives about 1,500 Watts of power per square meter from the Sun. In order to obtain enough power to migrate the Earth in the right amount of time, we'd need to build an array (in space) that collected that entire 4.7 × 1035 Joules of energy, evenly, over a time period of two billion years.

Gravity is determined by how much mass a given material has, so the more mass an object has, the stronger its gravitational pull. ... "The Earth's gravity field changes from one month to the next mostly due to the mass of water moving around on the surface," said Watkins.

Larger Capacity: The carrying capacity of the railways is extremely large. Moreover, its capacity is elastic which can easily be increased by adding more wagons.
