What is the attractive force that exists between all objects?
gravitational force
What is the angular tilt between the ecliptic and the celestial equator?
About 23.5 degrees.The celestial equator and the ecliptic are two "great circles" on the sky coordinate system.Think of them as two hoops of the same size, hinged together at two points (well the hinged points do move but very slowly taking about 26 000 years to move around and come back to the same place again). If you hold onesteady and spin the other one inside it, they stay connected at the two hinges, but they canbe set at any angle to each other.Now put them in the sky. Place the steady one right above the equator all the way around, and tiltthe movable one on the hinges so that it makes an angle of 23.5 degrees with the steady one.The steady one, above the earth's equator all the way around, is the celestial equator. The movable one,tilted 23.5 degrees to the equator, is the ecliptic ... the path that the sun appears to travel in the sky,once around in a year. The hinges ... where the ecliptic crosses the equator ... are the points where thesun is located at the time of the two equinoxes. Halfway between the hinges are the points where thetwo circles are farthest apart ... one where the ecliptic is farthest above the equator, the other whereit's farthest below. Those are the points where the sun is located at the time of the two solstices.
What is gravity and how does it affect earth?
gravity is the force that keeps objects on the earth, if we didn't have gravity we would just float away
What is a good description of magnets would be?
The description of magnetism is the force of repeling or attracting which is used in everyday life.Magnetism is the property of an element to attract objects of certain magnetic property towards itself. These certain magnetic substance are classified under these 3 categories:-DiamagnetismParamagnetismFerromagnetism
What material would be the most appropriate to represent the asthenosphere?
The material that would be the most appropriate to represent the asthenosphere is Oobleck, corn starch and water mixed together, because it is not liquid nor solid. The asthenosphere is nor liquid or solid. It is something in between but none exactly.
Where would the earth be located in a model of celestial sphere?
The celestial sphere has the Earth at the centre and all the objects in the sky situated on the sphere at infinite distance. Positions of the objects are described by two coordinates, which could be azimuth and elevation, or, in geocentric coordinates, declination and hour-angle.
What celestial events?
The word celestial comes from the same roots as heavens (or sometimes sky); usually a celestial event would usually be considered to be something that takes place beyond the earth's atmosphere. A celestial event might be something like an eclipse or occultation, a star going nova, a planetary transition, etc.
The intersection points between the ecliptic and the celestial equator are called?
Those would be the "equinoxes".
Distinguish between a celestial object and the universe?
When seen from some other part of our galaxy (which WE have named The Milky Way) our solar system would appear to be a celestial system. Any star with surrounding stars or planets is considered to be a "celestial system". Even this or other galaxies are considered to be "celestial systems".
What is the relationship between the celestial sphere and the local sky?
In this context the celestial sphere could be considered the background of stars, planets, comets, etc., such as is visible on a clear night, as distinct from the local sky would include Earth's atmosphere and weather effects such as an observer is largely limited to during the day (with the exception of the closest star, our Sun). It's safe to say these are relatively independent - objects in the sky such as meteorological phenomena, artificial satellites, etc., would move and act independent of the celestial sphere. Remembering that Earth is a planet in space moving in an orbit (revolving around its primary) and also rotating on its axis - because of which, the celestial sphere would seem to spin over the course of 24 hours, and also change throughout the year with respect to objects inside the solar system because of its position in orbit.
Who studies the summoonstarsplanets and other celestial bodies?
The sun, moon, stars, planets, and other celestial bodies collectively, would be the objects of study for astronomers. They would also be of interest to cosmologists and astrophysicists; there would also be specialists within these disciplines - for example the sun specifically would be of interest to a solar physicist or heliophysicist (or heliologist), planets would be the domain of a planetary scientist or planetary physicist, and so forth.
What rises in the east and sets in the west for an observer in New York?
Most natural celestial objects do this; exceptions would be any fixed star that is 'circumpolar'-- they are close enough to the celestial poles that they never appear to dip below the observer's horizon. Which stars are circumpolar depends on the latitude of the observer.
What is the imaginary sphere on which all objects in the sky seem to be located?
The imaginary line around which the earth turns is its axis.
How did the Greeks study the stars?
The ancient Greeks developed instruments such as the armillary sphere to track the movement of objects in the plane of the celestial equator against the annual motion of the Sun. This basic device consisted of a set of graduated rings that represented important circles on the celestial sphere, such as the horizon, the celestial equator, the ecliptic, and the meridian. These rings formed a skeletal celestial sphere. A movable sighting arrangement allowed early astronomers to observe a celestial object and then read off its position using the markings on the relevant circles.Ptolemy and other Greek astronomers used the quadrant, a graduated quarter of a circle constructed to allow an observer to measure the altitude of celestial objects above the horizon. An astronomer would sight a target celestial object along one arm of the quadrant and then read off its elevation from a scale (from 0 to 90 degrees) with the help of a plumb line suspended from the center of the quarter circle. With this arrangement a celestial object just on the horizon would have an elevation of 0 degrees, while an object at zenith would have an elevation of 90 degrees.(will add more if i find out more)

The place where the extended axis of the Earth would touch the celestial sphere is called the celestial what?
That is also called the axis; the "end-points" of this axis are called the celestial poles.
What is the definition of the word squishy?
Squishy is defined as something that is flexible when squeezed in between two points. A good example would be a sponge, when wet and squeezed between two solid objects it squishes to change form.
