What is the envelope of gas that surrounds earth?
My answer what i got is the layer of gases that surroud the earth is the atmosphere. so that's the answer to your question is the atmosphere is what surrounds the earth of layer of gases.
Difference in temperature of the varying layers of the Earth's surface where either of the rocks solidify,causes difference in size of grains of rocks.When solidified below the Earth's surface,the grains are comparatively larger crystals than extrusive igneous ones.Intrusive rocks form underneath the Earth's surface(eg.,granite). Magma cools slowly so it has time to form large crystals.Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form(eg.,obsidian).
What do computers use to absorb heat?
Computers do produce heat. However, they avoid actually absorbing it because to do so would make their temperatures rise which would destroy many of their electronic components. Rather they have fans and cooling fins which serve to _dissipate_ heat to the surrounding air. The fans move air past components, especially the CPU (central processing unit) and power supply, that produce most of the heat. The cooling fins provide large surface areas so that heat can move from metal to surrounding air most readily.
For pictures of the cooling fins used with CPUs search images.google.com for cpu cooling fins.
How do glaciers both remove and build up Earth's surface?
Glaciers remove Earth's surface through erosion, as they pick up and transport rocks and sediments. They build up Earth's surface by depositing these materials as they melt, forming landforms like moraines and drumlins.
If the air at 75 degrees is full of moisture and the temperature suddenly drops what will happen?
If the temperature suddenly drops, the air will not be able to hold as much moisture and will become supersaturated. This excess moisture will then condense out of the air, leading to the formation of dew, fog, or even precipitation, depending on how much moisture is in the air.
What erosional agent accounts for most of the erosion on Earth's surface?
Water is the erosional agent that accounts for most of the erosion on Earth's surface. It can take the form of rivers, oceans, rain, and glaciers, which all contribute to the shaping of the landscape through processes like erosion and sediment transport.
What general formula represents all fatty acids?
Fatty acids consist of Carbon (C), Hydrogen (H), and Oxygen (O) arranged as a carbon chain skeleton with a carboxyl group (COOH) at one end. The general formula is: CH3(CH2)xCOOH where x is the number of carbon atoms in the chain.
Which part of earth is hottest?
The inner core of the Earth is the hottest part, reaching temperatures of up to 5700 degrees Celsius (10,300 degrees Fahrenheit).
Why does warm water flow away from the equator?
Warm water flows away from the equator due to Earth's rotation and the Coriolis effect. As the warm water moves towards the poles, it gets deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating ocean currents that transport heat around the globe.
Where does the sun shine directly overhead on September 22?
The sun shines directly overhead at the equator on September 22 during the equinox. This phenomenon marks the beginning of fall in the Northern Hemisphere and spring in the Southern Hemisphere.
When an object appears to be shiny or pearly, it typically means that it has a smooth and reflective surface that is capable of reflecting light. This can create a lustrous or iridescent appearance, giving it a shiny or pearly quality depending on the material and light conditions.
Magnetite typically forms when iron-rich rocks undergo chemical reactions in Earth's crust under high temperatures and pressure conditions. It can also form in hydrothermal veins or as a product of microbial activity. The presence of magnetite is often indicative of a specific geological history and can provide insights into the formation processes of rocks and minerals.
What is the second largest city on EARTH?
The second largest city on Earth is Shanghai, China by population.
Biogenesis explains how life began on earth?
Biogenesis is the process of lifeforms producing other lifeforms, e.g. a spider lays eggs, which develop into spiders.
The term is also used for the assertion that living matter can only be generated by other living matter, in contrast to the hypotheses of abiogenesis which hold that life can arise from non-life under suitable circumstances, although these circumstances still remain largely unknown.
Until the 19th century, it was commonly believed that life frequently arose from non-life under certain circumstances, a process known as spontaneous generation. This belief was due to the common observation that maggots or mold appeared to arise spontaneously when organic matter was left exposed. It was later discovered that under all these circumstances commonly observed, life only arises from the replication of other living organisms
What properties does granite have that make useful?
Granite is the most durable natural material that is available in substantial quantity. It is more resistant to deterioration from weather and from chemicals than any other plentiful material. Those huge towers supporting the Brooklyn Bridge? Granite.
Cobblestones? Granite.
How do plants and animals mantain the level of oxygen in the atmosphere?
Plants produce oxygen during photosynthesis by using sunlight to convert carbon dioxide and water into glucose and oxygen. Animals, including humans, consume oxygen during respiration to produce energy and release carbon dioxide. This continuous cycle of oxygen production by plants and consumption by animals helps maintain the levels of oxygen in the atmosphere.
Stale air refers to air that has become stagnant and lacks freshness due to a lack of circulation or ventilation. It may contain higher levels of carbon dioxide, humidity, and pollutants that can impact air quality and contribute to discomfort or health issues. Renewing stale air by opening windows or using ventilation systems can improve indoor air quality and create a more comfortable environment.
Is a sea star a producer or consumer?
A sea star is a consumer because it feeds on other organisms such as bivalves, snails, and small fish. It does not produce its own food through photosynthesis like a producer would.
How old do geologists think the earth is?
Geologists estimate that the Earth is approximately 4.54 billion years old based on radiometric dating of rocks and meteorites. This age is determined by analyzing the decay of radioactive elements in these materials.
What is the most outer solid portion of the planet earth called?
The most outer solid portion of the Earth is called the crust. It is the Earth's thin, outermost layer and is divided into several large and small tectonic plates.
No, wulfenite is not magnetic. It is a lead molybdate mineral known for its vibrant orange to yellow color and forms in a tetragonal crystal system.
If the sun runs out of fuel of fusion this will be mean the end of life on earth?
this is what the scientist say when the sun reaches the end of it s life it will expand so much that all the planets in the solar system will be incinerated but you ned not worry this wont happen for a few billion years yet
