Is it possible to find diamonds in a coal mine?
It is not typically possible to find diamonds in a coal mine. Diamonds are typically formed in the Earth's mantle, while coal is formed from plant material that has been subjected to high pressure and heat over time. The two processes occur in different geological settings.
What causes the differences in the way diamonds form compared to graphite?
The differences in the way diamonds form compared to graphite are primarily due to the arrangement of carbon atoms. In diamonds, carbon atoms are arranged in a rigid, three-dimensional structure, while in graphite, carbon atoms are arranged in layers that can easily slide past each other. This difference in structure leads to the distinct physical properties of diamonds and graphite.
Are atoms in diamonds harder than those of graphite?
Diamonds are a crystallized form of carbon. While its atoms are no harder than any other carbon atoms, the arrangement of those atoms makes diamonds the hardest natural substance known to mankind.
Can diamonds become polluted or contaminated?
Not in the environmental sense of these words. Diamond is an allotrope of carbon; diamonds may form with other trace minerals in the lattice, such as hydrogen or boron, but once formed and erupted to the earth's surface, nothing will physically pollute or contaminate the stone. However, emotionally, some diamond stones are already polluted or contaminated based on who owned them in the past.
Which are some effects of metallic bonding?
Some effects of metallic bonding include high electrical and thermal conductivity, malleability, and ductility. Metallic bonds allow for the delocalized movement of electrons, making metals good conductors of electricity and heat. Additionally, the ability of metal atoms to slide past one another without breaking the overall structure gives metals their characteristic properties of being able to be hammered into thin sheets (malleability) and stretched into wires (ductility).

Who was the first space probe to fly past the moon?
The first space probe to fly past the Moon was the Soviet Luna 1 spacecraft in 1959. Luna 1 was intended to impact the Moon, but instead, it missed the Moon and became the first human-made object to enter orbit around the Sun.
First space probe to fly past the moon?
The first space probe to fly past the moon was the Soviet Luna 1 probe in 1959. Luna 1, also known as Mechta, was intended to impact the moon but missed and became the first human-made object to escape Earth's gravity.
Which industry has not been considered a natural monopoly for the past 30 years?
Diamonds
What were some uses of thermal energy in the past?
Trappers and Native Americans used the thermal springs in Yellowstone to cook food.
How did the past use thermal energy?
In the past, thermal energy was used for heating homes and buildings, cooking food, and for industrial processes such as metalworking and pottery making. Simple methods such as burning wood, coal, or oil were used to harness thermal energy for these purposes.

Who visited Venus first?
Mariner 2 spacecraft (USA) flew past in 1962. A "Venera" probe ( USSR) landed in 1970.
Does Austria mine for diamonds?
Mining takes place in Austria on a much less active basis than in the past. You can read more about its mining industry, below. Diamonds are not on a list of natural resources in Austria.
What is the name of the current US mars probe?
The current US Mars probe is called Perseverance. It landed on Mars in February 2021 with the primary goal of searching for signs of past microbial life and collecting samples for future return to Earth.
