What are Quartz talc halite magnetite feldspar mica?
These are names of different minerals commonly found in the Earth's crust. Quartz is a hard mineral composed of silicon dioxide. Talc is a soft mineral used in cosmetics and talcum powder. Halite is rock salt, composed of sodium chloride. Magnetite is a magnetic iron ore. Feldspar and mica are both common rock-forming minerals found in many types of rocks.
What two things do sedimentary rocks record?
Sedimentary rocks can record information about the environment in which they formed, such as the presence of water, wind, or ice. They can also preserve evidence of the organisms that lived in that environment, including fossils.
Compare and contrast igneous and metamorphic rock formation?
Metamorphic rocks are formed by heat and pressure. Sedimentary rocks are formed by Lithification. Metamorphic rocks texture depends on how much eat and pressure was exerted on it. Sedimentary rocks texture is usually fine grained. Not much i could find on compare.
Which part of Canada is very mountainous?
The western part of Canada, particularly the province of British Columbia, is known for its mountainous landscapes. The Rocky Mountains run through this region, forming rugged terrain and dramatic peaks that attract outdoor enthusiasts and tourists alike.
Evaluate how different factors affect reaction rates for a given industrial reaction?
There are thousands if not millions of Industrial Reactions going on all over this planet
There are hundreds of different factors which do affect each of the Industrial Reactions
The question is simple the answer is not
What is a measure of how much pulling or tension a material can withstand?
Tensile strength measures how much pulling or tension a material can withstand before breaking or deforming. It is an important property to consider in applications where materials need to resist stretching or elongation.
What is El Niño and when is the next El Niño year?
El Niño (and La Niña) refer to the movement of warm surface water (the first 200 metres deep is between 20 and 30°C) in the tropical Pacific Ocean.
When there is no La Niña or El Niño, the trade winds blow the warm water to the west Pacific. This brings rainfall to the countries there.
During a La Niña event, the winds blow stronger, increasing this rainfall. At the same time, on the eastern side of the Pacific, cold water is allowed to rise, reducing rainfall, but bringing nutrients to encourage fish and marine life.
During an El Niño event, the trade winds are weaker. This allows more warm water to move back towards the Americas, increasing rainfall there. The warm water blocks the nutrient-rich cold water from rising, reducing fish stocks. At the same time in the western Pacific the reduction in warm water means drier conditions, even drought to a country like Australia.
These phenomena are impossible to predict. They seem to happen every six or seven years, but we can't tell accurately.
Shows the inheritance of a particular trait over several generations?
Inheritance of a particular trait over several generations can be displayed using a Punnett square to predict the possible outcomes. By following the principles of Mendelian genetics, one can determine the probability of offspring inheriting the trait based on the genotypes of the parents. Observing how the trait is expressed in each generation helps track its inheritance pattern.
What are the particles in a soulotion?
Particles in a solution are typically the solute and the solvent. The solute is the substance that is dissolved, while the solvent is the substance in which the solute is dissolved. These particles are dispersed uniformly throughout the solution.
A metormorphic rock is formed by lava?
Metamorphic rocks are formed from pre-existing rocks that undergo changes in response to high pressure, high temperature, or chemically active fluids within the Earth's crust. These changes can occur without melting the rock. Igneous rocks, on the other hand, are formed from the cooling and solidification of magma or lava.
What year were soap bubbles invented?
Soap bubbles have been around for centuries, with records dating back to ancient times. However, the modern soap bubble as we know it today was popularized in the 17th century when it became a popular form of entertainment in Europe.
What happens to the temperature of a body of water when water molecules condense upon it?
The temperature of the body of water increases when water molecules condense upon it because condensation releases latent heat energy. This energy is transferred to the water, causing an increase in temperature.
What are four types of global winds?
The four types of global winds are the trade winds, westerlies, polar easterlies, and the jet stream. Trade winds blow from east to west near the equator, westerlies blow from west to east in the middle latitudes, polar easterlies blow from east to west near the poles, and the jet stream is a fast-flowing narrow air current in the upper atmosphere.
How does the electromagnetic force differ from the other three forces?
The electromagnetic force is carried by photons and acts between charged particles, such as electrons and protons. It is a long-range force, unlike the weak and strong forces, and it can both attract and repel particles. The electromagnetic force is also distinct from gravity, which is a much weaker force acting over longer distances.
What are the differences between the Canadian shield and the interior plains?
The Canadian Shield is a large geological region characterized by ancient rocks and extensive forests, covering a significant portion of Canada. In contrast, the Interior Plains are a vast region of flat or gently rolling terrain located to the west and south of the Canadian Shield. The Canadian Shield has more rugged topography and older rock formations compared to the relatively flat and younger sedimentary rocks found in the Interior Plains.
What is an Non example of a cell wall?
A non-example of a cell wall would be a mitochondrion. Mitochondria are membrane-bound organelles found in the cytoplasm of eukaryotic cells, but they do not have a rigid outer structure like a cell wall; instead, they have a double membrane structure that houses enzymes involved in energy production.
What is rate of change in science?
Rate of change is called a derivative. Differential equations describe relationships
between rates of change.
==================================
Answer #2:
The first answer is a microsoft answer: technically impeccable, totally uniformative,
and pragmatically useless.
"Rate of change" means (the amount of change)divided by (the time the change takes) .
Where does dynamic equilibrium take place?
Dynamic equilibrium takes place in a closed system where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, even though the reactions continue to occur. Examples include chemical reactions, such as the Haber process for ammonia production.
Alloying is necessary to improve the properties of metals, such as strength, hardness, corrosion resistance, and ductility. By mixing different metals together, engineers can create alloys with a combination of characteristics that are better suited for specific applications than pure metals. Alloying also allows for cost-effective ways to tailor the properties of materials to meet various requirements.
How far is the Equator from Chicago?
Chicago is at 41° 59' N latitude. The equator is a 0°N.
Basically, it's 42°(1° in latitude change is 69.2 miles
) * 69.2 miles = 2,906.4 miles
Theoretically, a battery consists of two or more cells, but in practice most people call a single cell a battery.
A cell is a physical unit that produces a specific voltage, for NiCd it is ~1.2 volts, for lead acid, it is ~2.1 volts.
A battery can be made of a single cell, or multiple cells. In the case of a 9 volt battery, there are typically 6 cells in series to produce the 9 volts (1.5 volts x 6).
AnswerA cell is a single source of electricity produced by a chemical action in the cell. A battery is simply a combination of cells connected electrically.
Fuel cells and batteries are similar because they use a chemical reaction to provide electricity. A battery stores the chemical reactants, usually metal compounds like lithium, zinc or manganese. Once used up, you must recharge or throw away the battery. A fuel cell actually creates electricity through reactants (hydrogen and oxygen) stored externally. The fuel cell will produce electricity as long as it has a fuel supply. In short, a fuel cell vehicle is refueled instead of recharged.
