1. Using a Key Which mineral is mined in the most locations?
son4ous [18]

Answer:

Coal: 7.4 billion tonnes

Explanation:

The World Coal Association estimates that there are more than one trillion tonnes of coal reserves worldwide, enough to last 150 years at current rates of production, so it is unsurprising to see coal ranked as the most-mined mineral in the world.

While China has consistently led the world in production – the country was responsible for 3.3 billion tonnes in 2016 – this was down 16% from the 3.9 billion tonnes produced in 2012. Chinese coal output slumped below the 3.4 billion tonne-threshold predicted in 2016 and the trend may continue, as renewable energy sources become more widespread.

The Chinese decline has mirrored a trend in worldwide coal production, which fell to 7.4 billion tonnes in 2016 from 8.2 billion in 2012. While coal production has increased in Australia and Russia in the last five years, both South Africa and the US have seen sharp declines in production of anthracite and bituminous coal. American coal production in particular has fallen from over 900 million tonnes in 2012 to 782 million in 2016, the lowest figure since 1979.

In this exercise we used global distributions of dinosaurs. How might the FADs and LADs differ if we focused on dinosaurs within
Alika [10]

FAD's and LAD's would differ if we focused on dinosaurs within a certain region because of migratory patterns. Similarly, focusing on species levels would decrease the available data.

FADs or First appearance datum is a term used by scientists to refer to the first appearance of a species. Like-wise, LAD is used to refer to the last appearance of a species in the record.

If we were to focus on dinosaurs within a certain region, the FAD's and LAD's may be quite different. This is due to the migratory patterns of certain dinosaurs. Perhaps a certain species has a much more distant FAD or LAD in one region than it does in another because that dinosaur may have taken many years to wander to another region of the Earth.

Like-wise, limiting our search to a species level can impact the LAD or FADs. The taxonomy hierarchy is as follows:

  • species
  • genus
  • family
  • order
  • class
  • phylum
  • kingdom
  • domain

increasing in scope, Domain is the level that holds the highest variety of organisms. In contrast, species is the most specific, so limiting our data to a single species level would greatly affect the LADs and FADs because it lowers the number of dinosaur species that we take into account.

6. Two students are located 800 kilometers apart on the same meridian of
alexgriva [62]

Two students are located 800 kilometers apart on the same meridian of longitude. They measure the altitude of the Sun at noon on the same day. They can use these measurements to calculate Earth's circumference.

<h3>How far does the Earth actually go around?</h3>

The equatorial diameter measures 7930 miles, which is a little more than the distance between the north and south poles, which is roughly 7900 miles. The Earth's circumference is simply equal to its average diameter, 7915 miles, multiplied by pi, where pi is 3.14159. This gives us an estimate of 25,000 miles for the circumference of the Earth.

The circumference and radius of the Earth, which have since been determined by orbiting satellites, are both quite near to the recognised contemporary estimates of 40,070 km and 6378 km, respectively. Since a circle's diameter is equal to twice its radius, the diameter of the Earth is 12,756 kilometres.

The circumference of the Earth depends on how it is measured. When it is measured around the equator, it is 40,075 km (approximately, 24,901 miles), whereas, if it measured from the north pole to the south pole it is 40,008 km (approximately, 24,860 miles).
