Why ozone doesn't settle to earth?
Ozone is a fairly unstable molecule. The ozone in the stratosphere will break down before it can diffuse to the surface.
umm 60times7 =420 therefore there are 420 secs in 7mins dude im 10yrs old and i know this its like kindergarden stuff lol
u probably used a calculator
P.S: SMOKE WEED ERRE DAY. HAPPY 4/20 AND SLAYER TO ALL
Is life on other planets possible?
Its not possible without some major modifications to the planet itself. We need the temperature, pressure, protective atmospheric layers and other atmospheric conditions to be just right, just to survive on the surface in the short term. For the longer term, we would need to be able to grow crops and have access to a fresh water supply.
There may be other planets with these properties already in place, but Earth is the only one in our solar system.
How far is Earth's magnetic axis tilted from its geographic axis?
The magnetic north pole, which is not the same as the geographic north pole is currently situated in the Canadian Arctic. It's moving towards Russia at a rate of about 55 km a year. So, the answer to your question will be different every time you ask it.
Was there more water on Earth one billion years ago or now?
There was likely more water on Earth one billion years ago compared to now. This is because the Earth's water content has remained relatively stable over long periods of time, with the amount of water cycling through the planet's systems.
Is there a hidden land in the center of the earth?
There is no scientific evidence to support the existence of a hidden land in the center of the Earth. The Earth's core is composed of molten iron and nickel, making it impossible for a habitable landmass to exist there.
What are some reasons to believe the earth is round?
Answer 1:
It's actually an oblate spheroid. We can know a few ways.
1. Pictures from space show that it is.
2. The shadow Earth casts on the Moon at times show that it is.
3. If you board a plane, and fly east, and keep doing so, eventually you'll return to where you started.
4. If Earth were flat, those on the edges would be gravitationally attracted to the center, not straight down as they are.
Answer 2:
Look how big it is. Everything that big is a sphere. Even the moon is a sphere.
Did the 3 gouges dam slow the earths rotation?
No, the Three Gorges Dam's impact on the Earth's rotation is negligible due to its size and mass relative to the Earth. The dam's reservoir has redistributed some mass, affecting the planet's moment of inertia, but this effect is incredibly small and cannot noticeably slow the Earth's rotation.
Do any other planets have an atmosphere like earths and if they did could it support life?
At the moment, no planets are known to have conditions similar to Earth's for supporting life. If there planets similar to Earth, there would definitely be living organisms of some sort. On the other hand, there is slightly less chance of sentinent life such as our own species existing.
Where the source of all energy comes from the planet earth?
The ultimate source of all energy on planet Earth is the sun. Solar energy is converted and stored in various forms such as wind, fossil fuels, and biomass, which are then used to power various processes on Earth.
How have scientists used radioactive dating to show that earth is about 4.6 billion years old?
Scientists have used radioactive dating by measuring the decay of radioactive isotopes in rocks to determine their age. By analyzing the ratios of parent and daughter isotopes in samples, scientists can calculate the age of the rocks. This method has shown that the Earth is approximately 4.6 billion years old.
How do satellites and computers work together to produce images of earth?
I have the same question in the textbook the answer is that satellites use sensors to detect changes in the wavelength of light that is reflected from earth surface. They send this information to computers on Earth, which process into images.
Additionally
Early satellite communication used radio-transmitters to transfer imagery and data to earth ground stations. Some fixed satellites today use microwave radio relay technology to communicate with the ground which is complementary to that of communication cables.
Some of the commercial satellites that capture imagery of the Earth include GeoEye and DigitalGlobe, which provide the imagery used by Google Maps, Google Earth, and others.
How long does the earths energy take to get to earth?
No propagation delay has ever been successfully detected or measured,
and the process is now believed to be virtually instantaneous, at least to
within a Planck interval.
Is water the only inorganic liquid that exists under conditions suitable for life?
No, other inorganic liquids such as liquid ammonia or liquid methane can also exist under conditions suitable for life, particularly in environments with extreme temperatures or pressures. These liquids may provide the necessary medium for life to thrive in unique environments such as the subsurface oceans of icy moons.
Would life exist without water?
Life on Earth would not exist as we know it without water. Water is essential for most biochemical reactions in living organisms, serves as a solvent for nutrients and waste, helps regulate temperature, and provides a medium for various biological processes to occur. Therefore, it is unlikely that life could develop or be sustained without water.
What are the consequences of the earths rotation?
The season are caused by the way the earth is tilted on its axis . when the North pole Leans toward the sun, it is summer in the northern half of the world and winter in the south. six months later, its winter in the north and summer in the south.
The axis sets the tempatures of our planet in the north and south.
It affests the tides and climate indeffinatly.
The Tsunami in 2002 in Indonesia was so bad that it actually knocked us off our Axis by .05 percent.
What are stars called that wink?
The Earth's atmosphere, which is always moving, makes stars appear to be twinkling.
A star that really is 'winking' is most likely an eclipsing binary star - two stars orbiting each other.
What is the distance from the earth to Australia?
Since Australia isn't a planet and is on the earth, it's roughly a distance of 0 miles/0 kilometers from the earth to Australia. However, depending on which country/continent you're on that isn't Australia, the distance will be greater and will vary.
What is the suitable temperature range for life on earth?
The suitable temperature range for the development of life on earth is different from the suitable range once life has developed. Once life has a strong foothold, evolution allows life to adapt to both increasing and decreasing temperatures, until it is able to survive in extreme environments at both ends of the scale.
What is all the earths land called?
The Earth's land is collectively called the Earth's crust, which is the outermost layer of the Earth's surface where all the continents, mountains, and other landforms are located.
What is the poetic name for earth?
The poetic name for Earth is often referred to as "Mother Earth" or "Gaia." These names personify the planet as a nurturing and life-sustaining entity.
How slow does the earth go round?
The earth spins a little over 1,000 mph near the equator. The earth spins about 0 mph near the north & south pole.
Who discovered the earths curcumference?
The Greek mathematician and astronomer Eratosthenes is credited with calculating the Earth's circumference around 240 B.C. using the angle of the sun's rays at two different locations and the distance between those locations. This method provided a reasonably accurate estimate of the Earth's size.
How many people dies every second?
There are many complex equations to work this out, but if you take into account the moons orbit and the position of the sun it can be defined as
S=Supermans Flight Path (FirstHalfOfYear:49 SecondHalf:51)
H=number of people in hospitals
I=Moons Orbit
T=The Time of day (Hours)
If it's the first half of the year Supermans flight path takes him through the northern hemispehere and therefore the earths rotation speed is slightly slower, this means that disease mutates and multiplies 0.07* slower than in the second half of the year.
The equation for this could be:
S*3/I + T * 52 + (H*365/52) = Number Of Deaths Per the Time Of Year
For today. The answer would be an outcome of average of 803pMinute
Why is acceleration due to gravity zero at the centre of the Earth?
Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull.
Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.
