We use models to explain how life and such is. my example is the sun model. How would you know the orbit of the sun without that model? Now i know its a pretty simple reply but this is a simple question also. just think about it for a while
What else can I help you with?
What name for Mechanical models of solar system in which planets can be moved at their relative velocities?
Orreries or planetariums are mechanical models of the solar system that can simulate the movement of planets relative to each other at their actual velocities. These models are often used to study and visualize the dynamics of the solar system.
How did Copernicus explain the retrograde motions of the planets?
All the models explain retrograde motion because it is such an obvious phenomenon. In Copernicus's model an outer planet goes into retrograde motion when the inner planet overtakes it so that it appears from the inner planet to be going backwards along the ecliptic.
How are molecular models similar to other types of models?
Molecular models, like other types of models, are simplified representations used to better understand a complex system. They help visualize and explain the structure and properties of molecules. Like other models, they are based on certain assumptions and can vary in complexity depending on the level of detail needed.
What is the main different between the geocentric and heliocentric models of planetary motion?
in a heliocentric system earth and the other planets revolving planet's a geocentric system ,earth is at the center of the revolving planets
How can studying earth help scientists understand other planets?
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
Explain what effect the moon's gravity has on the sea?
Due to the moon's strong gravitational pull, relinquished by other planets, tides are formed.
What molecule do scientists look for when they are investigating the possibility of life on other planets?
Scientists often look for the molecule water when investigating the possibility of life on other planets. Water is essential for all known forms of life and its presence can indicate the potential for habitability on other planets.
Which planets are often called the rocky planets and why are they called so?
Mercury, Venus, Earth and Mars are the Rocky planets. They are called so simply because they are rocky, their outer layer is solid. All other planets in the solar system are gaseous.
How do scientist develop their ideas or theories about the formation of the stars and planets?
First they study the subject, then they come up with questions that other people may want to know the answer to. After that, they use their studies and knowledge of physics to come up with a believable and reasonable way that something could be what they think it is.
What two planets are the sister planets?
Venus and Earth are often referred to as sister planets because they are similar in size and composition. They are both terrestrial planets with solid surfaces and are situated relatively close to each other in the solar system.
Is there any other planets other than your planets?
Yes.
How does each of the models of the universe explain the retrograde motion of planets?
This is nothing as complicated as "models of the universe"... it is a geometric phenomenon. For example, if an outer planet - outside the Earth's orbit - is retrograde, that simply means that Earth is overtaking that planet; temporary the planet seems to go "backwards".The main movement of planets is from West to East; but for part of each orbit, each planet will have an (apparent) movement from East to West - then it is said to be "retrograde".
