What is meant by inclination of the earth?
The Earth rotates round the Sun in a orbit that defines the 'Plane of the Ecliptic'. The spin axis of the Earth is inclined approx 67.5 degrees from the Plane of the Ecliptic. This inclination determines how far North and South of the Equator the Sun will be vertically overhead at least one day of the year. So the Tropics of Cancer and of Capricorn; those places; are 22.5 deg distant from the Equator. [90 - 22.5].
Can two people stand on opposite ends of the earth without being on water?
No, it is not possible for two people to stand on opposite ends of the Earth without being on water. The Earth is mostly covered by water, so if two people were on opposite ends of the Earth, at least one of them would have to be standing on water.
Who was the narrator in journey to the center of the earth?
The narrator in "Journey to the Center of the Earth" is Axel Lidenbrock, a young professor of mineralogy. He tells the story of their adventure to the center of the Earth alongside his uncle, Professor Otto Lidenbrock, and their guide, Hans Belker.
What is the purest thing on earth?
That is kind of a malformed question there is no definition of 'thing', if you mean element are you refering to man made or natural source? The most pure element is anything that os constituted entirely of that element. so anything is the purest thing as it consists entirley of itself.
Which Earth material has the highest albedo?
Probably snow, if your Earth includes the totality of items found on the planet. Some clouds would have an albedo almost as high - but only in parts.
If you wish to limit your answer to earth solids, then perhaps milky quartz, and marble would have a high albedo.
How does heat pressure affect the core of the earth?
Heat and pressure in the Earth's core create convection currents that drive the movement of Earth's tectonic plates. The high temperatures and pressures in the core also sustain the Earth's magnetic field through the process of geodynamo. Overall, heat and pressure in the core play a crucial role in shaping the Earth's geology and maintaining its magnetic field.
There is no maximum size that icebergs can have; they will be as big as gravity, temperature and 'local' factors will allow.
The largest iceberg that has so far been documented, was an Antarctic iceberg that measured 335 x 97 kilometers (208 x 60 miles) which is larger than the country of Belgium.
One trigger of mass movement is the pores in sediments filling with what?
Water and sediment are common substances that can fill the pores in sediments and act as triggers for mass movements. When the pores become saturated with water, it can decrease the strength and stability of the sediment, leading to events like landslides or debris flows.
What is Sediment laid down by glacial meltwater?
Quick clay would be one phase, where the material is very fine, saturated with liquid, and prone to liquefaction.
Varves would be another (word derived from the Scandinavian for wave), and presents as well-layered fine silt on the bed of a glacier fed lake. Probably a seasonal process, with a graded particle size.
Outwash Gravels are a little more remote from the glacier, and are generally re-mobilized moraine materials. These will show a dendritic pattern of the streams that formed the deposit.
What indicates the motion of the Earth?
First you must be aware of your assumptions. It is well known that the Egyptians measured the angle of sunlight on two wells and computed the circumference of the Earth from those measurements. The Chinese did the same thing, but they assumed the Earth was flat and computed the sun's altitude. Both got reproducible results, but one group had a false assumption. This problem comes up in everything you do.
We assume that a body in motion tends to continue in motion at a constant speed in a straight line unless acted upon by a force. We can't prove that is always true, but if it is not then the universe is run by magic and we can never know anything.
Now we hang a pendulum and watch it swing. The pendulum swings in a straight line, back and forth as the force of gravity acts upon it. We observe that the swing appears to rotate, but we insist that it swings in a straight line, so the Earth must be turning beneath it. This is called a Foucault pendulum (pronounced "foo-co").

Motion of the Earth around the sun depends even more heavily on assumptions. For a long time people thought the Earth was motionless and the planets followed complex circles. That led to a lot of inventions in geometry and clever mechanisms called "orrery". Several philosophers eventually persuaded everybody that better results were obtained by assuming that the Earth moved around the sun.

If you don't believe a concept then by definition it does not make sense. The fact is believing is seeing. Everybody who looks at the stars sees the same blobs of light. If you believe in gravity then you can see evidence of gravity at work. If you don't believe then you can not see the evidence and nobody can persuade you that it is there. This is significant because gravity is not the only theory about how the universe works. Another group says electric charge is the main factor in how the universe behaves. Both sides of this argument consider the other side to be deluded. And these are *scientists*.
So always be aware of your assumptions before you make any conclusions.
Mother Earth can regain strength by reducing human impact through sustainable practices like renewable energy, regenerative agriculture, and conservation efforts. Promoting biodiversity, reducing pollution, and restoring ecosystems are also critical. It is essential for individuals, communities, and governments to work together to prioritize the health and well-being of the planet for current and future generations.
Why do s waves stop when they reach the liquid outer core?
S-waves stop when they reach the liquid outer core because liquids are not able to support the shear stress required for S-waves to propagate. S-waves rely on the solid state of materials to move in a back-and-forth motion, which is impeded in a liquid. This change in medium properties causes the S-waves to be absorbed or converted into other wave types, such as P-waves.
What would the earth look like if the both polar caps melted?
Since most of the northern polar cap is already floating, this would cause little effect. But if the Greenland caps melt, as appears to be happening, then this will contribute to sea level rise. But this will be partly counterbalanced in the long run by isostatic rebound of that landmass.
But as rock is several times as massive as ice, there will accordingly be a lesser volume of land rise than that mass of ice that melted. [Archimedes strikes again!] The isostatic rebound would take centuries - Scandinavia is still rising in response to melting at the end of the last ice-age .
The southern polar cap is mainly above the land mass of Antarctica, and could contribute as much, in an extreme position, as a 4% rise in sea level. (~160m)
But since the seas would flow over low lying land, the maximum credible sea level rise would be less than one half of that. The Antarctic Continent would also rebound, but once again, the time scale is centuries.
With the removal of the ice mass, and the rebound of the landmass, a greater and different space would be available for the magma, and the possibility of volcanic action is non-zero.
She can regain strength by connecting with nature and finding solace in its healing properties. Engaging in grounding activities like walking barefoot on the earth, practicing deep breathing exercises outdoors, and spending time in green spaces can help her feel reinvigorated and better able to cope with the challenges she is facing. Mother Earth's resilience and transformative power can serve as a source of inspiration and guidance for her own journey towards healing and reshaping her condition.
What percent of land is occupied by terai?
The Terai region occupies about 17% of the total land area of Nepal.
What is on the very top of the earth?
At the very top of Earth is the North Pole, which is located at the northernmost point on the planet. It is a geographic coordinate where all lines of longitude converge and is covered by a constantly shifting ice cap.
How much of earths surface is covered in land?
About one third of the land surface of the earth is desert.
Yes...After We died we will Be reborn on earth and have a different life but everything will be the Same and you'll won't remember you'll first life on earth when we be reborn this will be like our first life on earth but there won't be any video games or same tv show like we do now we will have same family but you'll be in the same city like you are now but you are going to be different school then right after you died from your second life on earth then you'll be in heaven or hell
What are the reasons earth doesn't overheat?
Earth doesn't overheat because of its atmosphere, which contains greenhouse gases that trap heat from the sun. The balance between the incoming solar radiation and the outgoing heat helps regulate Earth's temperature. Additionally, the presence of reflective surfaces like ice and clouds also help in maintaining a stable temperature.
What was earths atmosphere made up of?
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.
What does a flax seedling look like?
Dude, I'm really good with flowas! they the bomb-diggity. I flax seedling looks kinda flax-ish. It also has the shape of a seedling. Its called a flax seedling, so you know, that's what it looks like. those flax seedlings are just the best. i love just staring at their flax body. its nice.
How does the Earth's atmosphere make lie possible on this planet?
The Earth's atmosphere plays a crucial role in supporting life by providing the oxygen necessary for respiration. It also helps regulate temperatures, shields us from harmful solar radiation, and contains greenhouse gases that maintain a hospitable climate. Overall, the atmosphere creates the conditions necessary for life to thrive on Earth.
What region of the world has the most number of foggy days?
The region of the world with the most number of foggy days is typically coastal areas with cool ocean currents, like Newfoundland in Canada and coastal Chile. These areas experience frequent fog due to the interaction of warm air temperatures with the cold ocean waters.
