Austrians typically get around using a combination of public transportation, such as trains and buses, as well as cycling and walking. In larger cities like Vienna and Salzburg, there are extensive public transportation networks that make it easy for residents to travel within the city and to neighboring towns. Additionally, many Austrians own cars for longer trips or for areas not easily accessible by public transport.

So 1st there was a big mass cloud of dust, gas and debris called a nebula 4.6 Billion years ago. Then a nearby star exploded. Thats called a Supernova. The force of the explosion caused the nebula to start "spinning." Everything starting crashing into each other. The collision between the material cause much of the materials to "glue" together. Eventually, 99% of all the mass from the Nebula became the center, which is our Sun. While everything else, the 1% became the celestial bodies like the planets, stars, moons, etc.

Gravity is the force that pulls all objects towards the center of the earth. So the effect of gravity on moving objects is that it pulls them back towards the center of the earth, causing friction with the any surface beneath them.

The first planet orbiting the sun is Mercury, and the last planet is Neptune. Mercury is the closest planet to the sun, while Neptune is the farthest.

It has to do with something called the Schrodinger equation, which is a mathematical representation of what an electron will do in a nucleus. Basically, unless you can do fairly difficult differential equations, it's best to accept that they are.

If you can, check out the Wikipedia page for the equation. It goes into far more detail than makes sense to do here.

"Ordit" is not a recognized term or concept. It may be a misspelling or abbreviation that needs further context for proper clarification.

If a small moon were to collide with Earth, the impact would likely generate extreme heat, tsunamis, earthquakes, and mass destruction. The resulting chaos would lead to widespread devastation and loss of life, making it very likely that humans would not survive such an event.

A fully developed thunderstorm typically has an anvil shape, with a towering cloud structure known as a cumulonimbus cloud. This cloud can reach high into the atmosphere and have a flat, spreading top due to strong upper-level winds. Thunderstorms produce heavy rain, lightning, thunder, and sometimes hail.

I think you may be referring to the gyroscopic effect of the rotation of the Earth. As with any stable gyroscope, it is their stability that makes them a reliable reference.

The V1 ram jet buzz bombs of the war used a gyroscope to maintain a stable path. Violently upsetting the device by tipping the wing threw the gyroscope into chaos and caused them to drop short of their target. Gyroscopes rotate at enormous speeds to achieve this stability and someone please correct me, but I believe 100,000 rpm is not unusual.

Mass and rotational velocity, totally devoid of gravitational influences. It is this which causes the Earth to maintain its angle of tilt, totally irrespective of its rotation around the Sun. It is interesting to compare the angles of tilt of the other planets as well.

The mystery to me is why most of the planets remain on the same plane as the Ecliptic.

Compared to the various angles of tilt, that stability is remarkable and fairly obviously an influence deriving from the Sun.

An interesting study but without ONCE mentioning the spinning planet, but wait, how stupid of me, that's what the gyroscopic effect of the rotation of the Earth is.

meteoroids, entering the Earth's atmosphere and burning up as meteors or shooting stars. Some larger pieces that reach the Earth's surface are known as meteorites. These debris can come from asteroids, comets, or other celestial bodies in the solar system.

A lunar eclipse can only occur during a full moon when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This can result in a partial or total eclipse of the Moon.

The Sun is the main basis for many stellar parameters. A far as luminosity goes - it is 1.

Yes, that is close enough for most purposes. 365.2422 days in a year, 360 degrees in a complete circle (year). If you divide, you get 0.9856 degrees per day. This is an average, since Earth's orbit isn't exactly circular.

No, the outer planets, also known as gas giants, are made predominantly of gas and liquid rather than rock and metal. They do not have solid surfaces like the inner rocky planets (Mercury, Venus, Earth, Mars) and are primarily composed of hydrogen and helium with small rocky cores at their centers.

Sort of.

Its just part of a nebula, and the collapsing "ball" must convert itself into a disk (the spin and the local gravity field will do that).

To get planets you need something solid (i.e. dust. the chief aggregators are those elements which have polarity, thus metals, ice, and stone {silicon oxide}) to condense and aggregate (thus the first stars had no planets). The "balls" don't spin unless two or more "planetoids" hit each other in such a way to produce a spin

A star that is gravitationally bound to another star can either be part of a binary star system, where two stars orbit around a common center of mass, or be part of a star cluster, where multiple stars are held together by gravitational forces within a common region of space.

It used to make a huge difference. When telescopes were poor and space flight was unheard of. Nowadays the telescopes such as Hubble and Spitzer Infrared mean the we can see exactly how big, bright, and colourful a star is. So to answer the question: To the naked eye, yes. But with a descent telescope, absolutely not.

The movement of rocks around the planet is primarily driven by the processes of erosion, weathering, and tectonic activity. Erosion by water, wind, or ice breaks down rocks into smaller particles which can then be transported to new locations. Tectonic activity, such as plate movements and volcanic eruptions, can also contribute to the movement of rocks across the Earth's surface.

Jovian planets generally have larger diameters than terrestrial planets. The average diameter of terrestrial planets like Earth is around 12,742 km, while the average diameter of Jovian planets like Jupiter is around 139,822 km. This difference is due to Jovian planets being mostly composed of gases and having less dense materials compared to the rocky composition of terrestrial planets.

The metamorphism caused by extreme heat and pressure is known as regional metamorphism. When a meteorite collides with the Earth, it can create impact metamorphism in the surrounding rocks, characterized by high pressures and temperatures from the impact event.

Saturn has rings that are divided into hundreds of small ringlets. These ringlets are created by the gravitational interactions between the planet's moons and the ring particles.

1. Presence of liquid water: Water is essential for biochemical reactions and serves as a solvent for various molecules.
2. Suitable temperature range: Life requires a temperature range where chemical reactions can occur and biological processes can function.
3. Energy source: Organisms need an energy source to drive their metabolic processes, such as sunlight in photosynthetic organisms or organic matter in heterotrophs.
4. Stable environment: Consistency in factors like temperature, pH, and nutrient availability is important for life to thrive and evolve.

• The words 'solar system' refer to the Sun and all of the objects that travel around it.
• Our solar system is made up of a star - the Sun - eight planets, 162 moons, dwarf planets and a bunch of comets, asteroids and other space rocks.
• The eight planets that make up our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
• Our solar system is part of a galaxy known as the Milky Way.
• The study of objects in the night sky (stars, galaxies and other things) is called astronomy.

Most stars produce a lot of light but inert stars while they produce light do not produce much heat. An inert star is a star that has begun to collapse because not enough heat is being generated by its nuclear core.
