Planet Earth

The oxygen in the air of earth is the result of biological processes over the past 4000 million years.

Trees give out oxygen as they photosynthesize

-------------------------------------------------------------------------------------------

Initially Earth's atmosphere did not contain free Oxygen (we know this from the chemistry of sediments that were first formed). Life on earth then happened and by the process of photosynthesis slowly began releasing Oxygen into the environment. At first this Oxygen reacted chemically with stuff (eg Iron salts) in the environment but over time all this "stuff" was converted and free Oxygen began to appear in the environment. This speeded up the development of life and about 600 million years ago there was enough Oxygen for life to use it to build calcareous shells and eventually for life to move onto the land. Thus life has made the planet we have today, Earth has been "terraformed" and now has an Oxygen rich atmosphere.

Interesting question. It depends on what time of day it was where you are when it reversed. If it was more than halfway through the light cycle of the day (sunup to sundown) then it would lengthen that perticular day assuming that the earth resumed the same speed of rotation that day but in the opposite direction. In other words if you have already gone through 8 hours of sunlight then you should get another 8 hours of sunlight for 16 total. If where you are has only gone through 3 hours of sunlight that morning then you will theoretically only get another 3 hours of sunlight as the sun was closer to the horizon and doesn't have that far to go before it sets again. Now here's the big clincher. If that happens then we all die and it won't really matter. The amount of gravity we have is dependant on the rotation of the earth. At the point of no rotation or even less rotation the gravity will change dramatically. God saw to it that everything on the earth was perfect for our survival. Speed of rotation, distance from the sun, temperature, atmosphere, etc... That is why there is no life (that we know of) on the other planets in our solar system.

The answer above by Freesinweasle is true, but I think the answer you are looking for is:

The question asks: How the lengeth of the solar day change?

Each time the Earth rotates around once on its axis, it moves a small distance along the its orbit around the Sun. Earth, therefore, has to rotate through slightly more than 360 degrees for the sun to return to the apparent location in the sky. Thus, the interval of time between noon one day and noon the next day(a solar day) is slightly grater than one true rotation period(one sidereal day). Our planet takes 365 days to orbit the Sun, so the additional angle is 360/365 = 0.986 degrees. Because Earth is rotating a the rate of 15 degrees per hour, takes about 3.9 minutes to rotate through this angel., the solar day is 3.9 minutes longer then the sidereal day(i.e, 1 sidereal day is roughly 23h 56m long). So the solar day would decrease by 7.8 minutes.

To create a slash on a world tour, you would need to organize a series of concerts or performances in various cities around the world. This would involve securing venues, coordinating travel logistics for the band and crew, and promoting the tour to attract audiences in each location. It's important to plan ahead and consider factors like transportation, accommodations, and local regulations in each country.

No, scientists do not agree that the world will end in the year 2000. Predictions about the world ending are not supported by scientific evidence and are considered pseudoscience. The world continues to exist beyond the year 2000 based on scientific understanding.

Earth is unique among planets in our solar system because it has liquid water on its surface, which is essential for supporting life as we know it. It also has a diverse range of ecosystems and a protective atmosphere that shields it from harmful solar radiation. Additionally, Earth has a strong magnetic field that helps protect it from solar winds.

The diameter of the earth at the equator is about 25,000 miles, or about 40,000 kilometers

An area in the desert with a water source is called an oasis. Oases are valuable resources in arid regions, providing essential water for plants, animals, and human settlements in the desert.

Planet Earth is made from meteors. Each meteors contained Hydrogen and Oxygen (H20). 5% of the rock was water.

When Earth settled down and the top layer became solid (The Crust) but still really hot, that 5% from every rock evaporated causing clouds that would rain from thousands of years.

Within our solar system, it's really easy to tell each planet's distance from the sun.

From Newton's law of gravitation, we realized that the time it takes a planet to revolve around the sun only depends on the planet's distance from the sun, and if we know the distance of one of them, we can figure out all the others.

If we watch a planet move through the sky, we can see how long it takes for that one to revolve once around the sun. Then we need to know both the distance and time of one planet, and from that one we can calculate all the others.

The one for which we know both the distance from, and time to orbit, the sun, is ... our Earth ! With this information, plus watching another planet to see how long it takes to orbit the sun once, we can calculate how far it is from the sun.

the earth's crust is made up of solid, naturally occuring assemblages of minerals called rocks. The huge diversity of the earth's rocks has developed over millions of years through ingenous activity, changes in form(metamorphism), and the formation of sediments and sedimentary rocks.

No, the Earth is not getting bigger from dirt. While sedimentation and volcanic activity can add material to the Earth's surface, the overall mass of the planet remains constant. The Earth accumulates material from various processes, but it does not result in a net increase in size.

Point-to-Point Protocol, or PPP, is a data link protocol commonly used to establish a direct connection between two nodes over serial cable, phone line, trunk line, cellular telephone, specialized radio links, or fiber optic links

Orbit is not a place - its a loop/curved-path that heavenly objects follow to revolve around. Consider two equally massive heavenly objects, A & B (round about the size of the Sun) with distance of few light minutes in-between. The gravity of object A will attract object B towards itself and so will object B attract object A towards itself. As both of them move towards each other, they will fall towards the center of each other. However, they both will move so quickly that gravity will pull them in a curved path and both of the objects will continue to fall indefinitely towards each other's center. The result would be astonishingly both, A & B setting curved-path/orbit around each other. Obviously, the result would have been different if one object were more massive than the other, like in the case of our Solar system - The star Sun is many times more massive than all the planets orbiting around it. An object with more mass will always have more gravity hence objects with lesser gravity, and no other influence, will always orbit around it.

If by orbit you meant space, then space isn't up there, but everywhere. Everything in the universe is in space including our planet Earth. Its more like the planet Earth has a dense atmosphere which traps heat, gases and vapors from escaping. As Earth's atmospheric pressure drops to about 1 Pa at 100 km altitude so, the mark 100 km (60.2 miles) is internationally considered as space.

It depends on whose definition you use. If you include Hong Kong, Macau and all the territories claimed by both China and India as part of China, then the USA is the fourth largest country by area (China third.) If you exclude them, then China becomes the fourth largest (the USA third).

The fourth largest country on Earth by population is Indonesia, with around 250 million people.

Isolation is the amount of solar energy, direct or diffuse, reaching a surface per unit of time. More precisely, insolation is the solar powerdensity incident on a surface of stated area and orientation, usually expressed as watts per square meter (W/m2) or BTU per square foot per hour. The word is a contraction of "incident solar radiation;" not to be confused with insulation.

Insolation values for a specific site are sometimes difficult to obtain. Weather stations that measure solar radiation components are located far apart and may not carry specific insolation data for a given site. Furthermore, the information most generally available is the average daily total - or global - radiation on a horizontal surface. To learn more about solar and other resource data, visit the external sites listed below.

When sunlight reaches the Earth, it is distributed unevenly in different regions. Not surprisingly, the areas near the equator receive more solar radiation than anywhere else on Earth. Sunlight varies with the seasons, as Earth's rotational axis shifts to lengthen and shorten days with the changing seasons. For example, the amount of solar energy falling per square meter on Yuma, Arizona, in June is typically about nine times greater than that falling on Caribou, Maine, in December. The quantity of sunlight reaching any region is also affected by the time of day, the climate (especially the cloud cover, which scatters the sun's rays), and the air pollution in that region. Likewise, these climatic factors all affect the amount of solar energy that is available to photovoltaic systems.

The land masses of the Earth that support life are called continents. They are large, continuous areas of land that are home to diverse ecosystems and a wide variety of plant and animal species.

The Earth has more water than land. Around 70% of the Earths surface is water and 30% is land.

Well, never is hard to say, because at one point in history, most of the continents were near the equator, meaning they were in rain forest regions.

But as for your question, I would have to say the Sahara Desert or the Arabian Desert. They get less than 0.2 inches (.508 cm.) of rain per year.

If you don't include snow as rain, then it would have to be Antarctica.

If the earth was not round and was cubical, all the places on will experience temperate weather while there would be no place with equatorial weather. However, that will happen if it rotates on the corners of the cube.

A strange concept, a cubic planet; but it's a more profound question than you might think because it is a throw-back to the early days of the science of geology.

When late-18C to 19C geologists started to try to understand the planet's internal structure and how mountain ranges form, they had realised the Earth had started as a ball of molten rock and gas so treated the problem as one of straightforward cooling by radiating heat into Space. Therefore, they thought, folds, faults and mountains were effects of contraction simply straining the Crust, whose structure was not yet really known. (Radioactivity was not yet discovered so they did not yet know the Earth has an internal heat source, let alone know its nature.)

One accompanying, early, idea was that contraction would eventually pull the globe into a rough polyhedron: certainly not a cube, but still facetted, perhaps a dodecahedron. This far-fetched notion might have been related to observing how some liquids freeze into polyhedral plates or prisms. (E.g. sun-baked mud-flats, basalt columns.)

The Earth's orbit is not a perfect circle but an ellipse due to gravitational influences from other planets. This elliptical shape varies over thousands of years due to the gravitational pull of other celestial bodies, such as Jupiter and Venus. A complete cycle, known as eccentricity cycle, takes about 100,000 years to complete.
