Help me please I will give brainliest. Models are important in science. Some models are verbal models, which are full elaborate descriptions that can help someone visualize the concept. You have seen various visuals of Earth's layers. Create a verbal model of Earth's interior. In your model, describe the following: (6 points)

The main layers of Earth's interior and the indirect evidence that helped us determine the layers.
The flow of matter in the mantle and in the core and the effects of that flow.
The source of thermal energy and how energy flows throughout the layers. (Hint: think of the cause of the convection currents)

Btw I need like a paragraph it's not multiply choice

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

Astudent conducts an experiment to determine how the amount of water given to a plant affects its growth. what is the independent variable for this experiment?

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
