B. The air moves from low to high pressure systems.
C. The air moves from high to low pressure systems.
D. The heating of the earth’s surface does not affect pressure.
whoever gets it right gets brainilest!!!
SCIENCE
Answer:
The Air moves to high to low system.
Explanation:
I think because of hot temperature it is hot.
The correct statement about pressure distribution due to uneven heating of the earth’s surface is the air moves from low to high-pressure systems. The correct option is B.
What is pressure distribution?Pressure distribution is sometimes different in different areas. This happens due to the uneven warmth of the earth. The uneven heating causes a difference in temperature and cause different pressure in areas.
Where there is a low temperature, the air pressure is higher. During uneven heating, the air blows from low to high-pressure systems. The uneven heating of the earth is due to the reason that water heat slower than the land. This causes air to warm and expand and rise.
Thus, the correct option is B. The air moves from low to high-pressure systems.

A group of students is investigating whether air resistance depends on the size of an object. The students throw two paper pieces each with the same force. One piece of paper is flat and the other is scrunched into a ball. The distance traveled by each paper piece is shown.
Experimental Observations
Student 1 Student 2 Student 3 Student 4
Distance traveled by flat paper 0.2 m 1.2 m 1.5 m 0.8 m
Distance traveled by scrunched paper 1.5 m 2.4 m 3 m 2 m
What was the test variable (independent variable) in this experiment?
Distance traveled by flat paper
The shape of the paper
Distance traveled by scrunched paper
The number of students
Answer:
The shape of the paper.
Explanation:
Flat Piece of Paper: Flat, (quite obvious haha) and not the easiest to throw
Scrunched up piece of paper: Easier to throw because it's simply in the shape of a ball, hence a ball being easy to throw. (:

Indentify each stage on the diagram with the name of the stage? PLEASE HELP
Answer:
1.black dwarf
H.white dwarf
A.Red giant
B.Main sequence
C.Nebula
D.Stellar nursey
Explanation:
On the last part where the main sequence happens, it really depends on the mass of the star using the sun as an example, our sun has a low mass meaning when it close to its dying form it would go to Planetary Nebula then collaspe as a white dwarf. When a massive star goes through the main sequence and it reaches its dying form, with the high mass it'll also die as a white drawf when it has very high mass it'll possibly end up as a black hole.
Hope this helps, sorry if it doesn't!

The absolute age of a rock is the aproxímate number of years ago that the rock formed the absolute age of ingenious rock can best be determined by
Answer: comparing the amount of decayed and undecayed isotopes
Explanation:
The absolute age of the ingenious rock can be best determined by radiometric dating, which analyzes the amount of two different isotopes in the sample.
How absolute age of ingenious rock be determined?Radiometric dating, which analyzes the amount of two different isotopes in a sample, is utilized to determine the age of rocks. Radioactive isotopes decay in a predictable way, enabling geologists to determine the age of a sample.
Using equipment such as this thermal ionization spectrometry. It can be determined by examining the position of rock strata. The absolute age of a stratum of rocks or fossils is its numeric age.
Radiometric dating can be employed to establish absolute age, the ingenious rock having aged years ago to determine absolute age.
Therefore absolute age of the ingenious rock is determined by radiometric dating, having different isotopes in the sample.
