Planets formed from small amounts of debris that were attracted together because of gravity.
D. Planets formed from small amounts of debris that were attracted together because of gravity.
A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.
D. Planets formed from small amounts of debris that were attracted together because of gravity.

Which situation is an example of heat transfer by radiation?
Answers
Answer:
This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.
Answer:
the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.

Answer:
c
Explanation:
the wires are made of too many conductors
If a power line were broken then power would not reach the light. Which is possible.
If a wire to the light or to the box in your house was broken your light would not receive power, therefore not turn on. Again possible.
If the power plant does not produce enough electricity, although unlikely, that would cause you to not be able to turn on your light. Unlikely but it would be true is it happened.
Finally C is not likely, your wires in your house are most likely made of copper but too many conductors in the wire, not only wouldn’t happen, but would most likely not interrupt your light working.
The question asks what is NOT a possible cause. C is the only not possible.

Which phrase describes non-foliated rocks?
have grains in parallel layers
include quartzite and marble
tend to split along their bands
form from crystallized magma
Answers
Non-foliated rocks include quartzite and marble. Therefore, option (B) is correct.
What are the non-foliated rocks?Nonfoliated rocks less foliated texture because they commonly lack platy minerals like micas. They often result from regional metamorphism. Examples include quartzite, marble, hornfel, greenstone, and anthracite.
Marble is low to high-grade metamorphosed dolostone or limestone both of which are carbonate rocks, They are made of dolomite grains or interlocked calcite. Marble is very often carved in the artwork of palaces.
Quartzite is quartz sandstone that is medium to high-grade metamorphism. It is composed of interlocking grains of quartz and can be distinguished from sandstone because individual grains do not fall off during the rock is rubbed. Original sedimentary structures in quartzite will remain visible.
