Is the earth growing in size reference-diameter?
first you divide the number into 2 and then mulitply it by 1000. 1000 is representted in a kilometer. for example: 4,878 divide by 2=2816. then 2,816* 1000=2816000. you have to do this every time when making a amout in distance of a diameter of any shape into meters of a kilometer.
How is earth similar to a spaceship?
Earth is similar to a spaceship in that it is traveling through space on a set path, has limited resources for sustaining life, and requires careful management to ensure the well-being of its inhabitants. Both Earth and a spaceship must rely on self-contained systems for survival and efficient use of energy and resources.
Assuming both Earth and Planet 2 established the same calender system, dividing up each day into 24 hour periods, and each started their respective calender on the same day, the new year for both planets would coincide every 100 years, disregarding leap-years or alterations to time keeping.
How would be the duration of a day change if the size of earth decreased without a change in mass?
Simple Answer:
If the Earth shrinks, the day gets shorter and the Earth rotates faster. But, that involves certain assumptions. See below.
Angular Momentum:
This is a question about angular momentum.
If the change in size of the Earth is a result of an internal process and no external forces are involved, then total angular momentum is conserved. Angular momentum is the sum (integral) of all mass times velocity times the distance from the axis of rotation. That sum will stay the same as you redistribute mass with no external influences. If mass gets closer to the axis of rotation, then some mass has to go faster.
The moment of inertia of a uniform sphere is I=2MR^2/5. Angular momentum is L=I omega. Omega is 2 pi/T and the period, T, is one day. So, L=2 pi I T. (The Earth is not uniform, but the result is the same.) If you keep M fixed and the density uniformly increases, then omega decreases. We can't get too precise without discussing more details, but the simple analysis suggests, T/R^2 is constant, so the period is proportional to square of the radius. Halve the radius and the day decreases to one fourth.
Which blue green planet rotates on its side because of the tilt of its axis?
The blue-green planet that rotates on its side due to the tilt of its axis is Uranus. Its axis is tilted at about 98 degrees relative to its orbit around the Sun, causing it to essentially roll on its side as it orbits.
Without wind and water working together what would happen to the earth?
Without wind and water working together, the Earth's climate would become more extreme and less stable. Wind and water regulate temperature and distribute heat around the globe, which helps maintain balance in the climate system. Without these processes, certain areas would become much hotter or colder, leading to potentially catastrophic impacts on ecosystems and habitats.
Why can earth support life and mars cannot?
Mars unlike earth is to cold has a little bit of water and oxygen. it cant support human life- but there may be other creatures out there there on planet Mars that it can support . but if humans were there, we would die.
How does the distance on saturn compare to the distance of earth?
The distance between Saturn and the Earth varies as both planets travel around the Sun in elliptical orbits. On average, Saturn is about 1.2 billion kilometers away from Earth. This distance can change due to their orbits and can be as close as about 1.2 billion kilometers and as far as about 1.7 billion kilometers.
How do rain and snow most support life on earth?
Rain and snow provide essential water for plants to grow, which form the base of the food chain. They also replenish freshwater sources for animals and humans to drink. Additionally, snow acts as an insulating layer that helps protect plants and animals during the cold winter months.
Why do the planets look so small from Earth?
The planets appear small from Earth because of their great distance from us. Even though they are large celestial bodies, their size pales in comparison to the vastness of space. Our perspective from Earth makes them appear small in the night sky.
Is earth the only planet with soil?
No, other planets such as Mars also have soil-like material called regolith. However, the composition and properties of the soil on other planets may be different from that of Earth due to varying environmental conditions.
What is 53 percent of earths diameter?
53 percent of Earth's diameter is approximately 6,465 kilometers.
Why are hybrid vehicles good for the earth?
Hybrids probably have a very slight negative impact when compared to automobiles of similar size. They are far more complicated machines which will cost in terms of dollars and pollution. They are going to cost more to maintain and will probably not last as long this increasing their pollution footprint.
The hybrids shine in that they get about 10% (or more) better mileage then their non hybrid counterparts. This does reduce dependence on fossil fuels at the site of the automobile and increases the dependence on fuels at other places.
The two main points for buying a hybrid include "feeling good" about the environmental impact and a decrease in dependence in foreign oil. As far as environment, at best they are neutral.
Azimuth tells us the direction in which a celestial object can be seen. It is the angle (clockwise) between due north and the point on the horizon directly below the object. The azimuth of the Sun thus varies with the time of day and the time of year.
What does the earths rotation create?
The Earth's rotation creates day and night as different parts of the planet are exposed to the sun's light at different times. This movement is what causes the sun to appear to rise in the east and set in the west each day.
Mars is most like what part of earth?
Mars is most like Earth's deserts due to its dry and dusty surface, rocky terrain, and extreme temperature variations. Both planets have similar day lengths and experience dust storms, although the ones on Mars are much larger and more intense.
If by "causes" you mean what caused Earth to form - Earth was formed from the left over stuff that formed Sun. A nebula of dust and rocks was pulled together by its own gravity and formed the sun, but not all of it was pulled to the center of the mass and the residual stuff began to orbit around the Sun. These orbiting particles and rocks and asteroids collected into bands and eventually formed into the planets, including Earth.
Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1% trace elements, mainly Argon. The martian atmosphere consists of 96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen present only as a trace element. Where you to inhale the martian atmosphere you would suffocate. The atmosphere on mars is also very thin, only 0.06% that of the Earth's so your blood would boil etc. The temperature is also incredibly cold ranging from - 87°C, rarely going above freezing, so humans could not function there with no form of space suit.
Will God destroy the earth in one thousand years?
There is no way to predict this with certainty as it depends on one's beliefs. Many religious traditions do not specify an exact timeline for the end of the world. It's best to focus on living a good and fulfilling life in the present rather than worrying about distant future events.
How many miles would you travel if you go around the world at 15 degrees?
That all depends on the speed of your navigating device.
Earth is the only planet called Earth and the only one we know of that is habitable to us. Scientists suspect that planets similar to Earth orbit other stars, but it is very difficult to determine trains of such distant planets.
What is the 3rd Rock from the Sun's home planet called?
The home planet in the TV show "3rd Rock from the Sun" is called Earth. The alien characters in the show, who are from another planet, adopt the identity of a human family living on Earth.
Earth feels solid and firm beneath our feet, providing stability and support. It can feel cool or warm depending on the climate and the surface we are touching. The texture can vary from soft soil to hard rock.
