Write true if the statement is true or false if the statement is false. PLEASE HELP 1. The sun is divided into definite internal layers.
_2. The hottest part of the sun has a temperature of about 27 million °C.
3. During nuclear fusion inside the sun, helium combines to form hydrogen.
-4. A photon may travel through the radiative zone in just a few seconds.
5. Material that rises through the convective zone cools at the sun's surface.
6. The photosphere has a grainy appearance because it has several different colors.
7. The sun's corona has a much cooler temperature than its photosphere.
8. The sun's atmosphere consists of three layers.
9. A sunspot occurs where a loop of the sun's magnetic field breaks through the solar surface.
10. Sunspots usually occur in cycles that repeat every 21 years.

Which of the following is a consequence of urban heat islands? increased precipitation downwind of the city? increased precipitation upwind of the city? decreased winds within the city? increased winds within the city?

Describe the layers of the suns atmosphere?

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
