Banded iron formations are composed of alternating light and dark bands of chert.

<h3>What is chert?</h3>
  • Banded iron formations are made up of alternating light and dark chert bands.
  • Chert is a sedimentary rock that forms in a variety of ways and is almost entirely composed of silica (SiO 2).
  • When the siliceous skeletons of marine plankton are dissolved during diagenesis, silica precipitates from the resulting solution, biochemical chert is formed.
  • Chert layers, which occur as irregular beds or rounded nodules within limestone formations, are common in eastern Kansas.
  • Because it is harder than limestone, chert is more resistant to erosion.
  • The Flint Hills' chert-topped hills are the result of the landscape's uneven erosion.

Therefore, banded iron formations are composed of alternating light and dark bands of chert.

This purchase best represent land, as the factors of production

Land as a factor of production has a broad meaning and can take difference forms, from agricultural land to real estate to the available resources from a certain pieces of land.

<h2>Further Explanation</h2>

Land represents all natural resources available to create supply. Land includes raw property and anything that emanates from the ground. It can be a non-renewable or renewable resource. Non-renewable resources include commodities such as gold and oil and renewable resources such as timer.  

All this becomes capital goods when it is changed from its original condition. For example, farm land is considered to be natural resources, but a mall or shopping center built on it is a capital good. Also the cultivation of crops on land improves its utility and value. In short, the primary purpose of land is to generate economic value.  

Although, land as factor of production, is very essential part of many ventures. Its value can increase or diminish depending on the industry. For example, the most important investment in real estate business is land but land might not be an important investment in a technology company

The three other factors of production are labor, entrepreneurship and capital. These factors are needed mainly for supply. They are responsible for the production of goods and services in any economy.

Explain how clearing of land also has a detrimental impact on the water supply.
mixas84 [53]
Let's say that the land has pollution meaning there is trash everywhere and dead plants over there, with those types of pollution it will harm our water supply because sometimes the pollution can affect our water.
Clearing the lands that has pollution can do good for our water and our ecosystem. When we clean the lands, more plants are able to grow, animals build their homes there, etc. That means that the animals and/or plants have a drinking water that is safe to drink and isn't polluted because we cleaned the land and the water. 
Keep America clean.

Hope this helped :)

There are nearly 300 million passenger cars in the U.S. The average gas mileage is 25 MPG (miles per gallon) and each car is dri
Natasha_Volkova [10]

Answer:

1.0236 billion metric tons

Explanation:

Given Parameters

Number of cars = 300000000

Average gas mileage per car = 25 MPG

Average distance covered by a car in one year = 10000 miles

CO2 Emission = 8.53 kg/gallon

Derivations from the given parameters,

If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:

<em>10000 miles ÷ 25 MPG = 400 gallons </em>

The CO2 emission for one car in a year is:

<em>400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton) </em>

The CO2 emission for 300000000 cars in year is:

<em>3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons </em>
