The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.
how are magnetic field lines helpful when studying magnets?
Answer:
If the magnetic field lines are closer to each other, the magnetic field strength is generally stronger. For example, in a bar magnet, the magnetic field lines are always densest when they are close to either pole. This signifies that the magnetic field gets stronger as we get closer to its source.
Explanation:
Explanation:
Earth's magnetic field is thought to play an important role in making the planet habitable. Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, deflecting away solar wind that might otherwise eat away at the atmosphere.

Which increases the amount of thermal energy on Earth according to scientists?
An increase in greenhouse gases has trapped heat.
More heat from Earth’s core is being conducted to the surface.
There is more convection occurring on Earth.
The sun has grown brighter.
Answer:
More heat from Earth’s core is being conducted to the surface.
Explanation:
According to scientists more heat from earth's core being conducted to the surface increases the amount of thermal energy.
What is thermal energy?
Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.
These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.
