What effect does the spinning of the earth's core have?
A.it creates gravity
B. it creates matter
C. it creates mass
D. it creates the earths magnetic field.
Answer:
c
Explanation:
its c
Earth contains a spinning electric filed. The spinning of earth core creates its magnetic field. Thus, option D is correct.
What is a spinning body?A body which rotates in its own axis is called a spinning body. Earth rotates about its along with revolving around sun. The outer core of earth generates electric current. This is called telluric current.
Flow of this current creates an electric current which is parallels to the surface of earth. The direction of magnetic field lines will be perpendicular to the direction of current. But it comes stronger when parallel to current.
A rotating electric current results in the generation of a magnetic field. Thus spinning of earth core generates a magnetic field and therefore, option D is correct.

Examine the layers of rock. How does layering provide evidence for determining geologic age?
Answer:
the deeper you go down in to the rock the older the fossils get.
Explanation:
layering can provide evidence because the deeper you go down in to the rock the older the fossils get. So when the scientists go in to the rock they can say what animals lived in that time and what animal was the oldest.

We can verify the properties as follows;
1) Sour taste - Put some soda on your tongue
2) Corrode metals - Put a little soda on a clean metal surface
3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

Which of the following is a subsurface event that takes place during the rock cycle?
Group of answer choices
Cementing
Erosion
Melting
Weathering
Answer:
Melting
Explanation:
Could not have been erosion because erosion happens on the surface.
Could not have been weathering because weathering happens on the surface.
So we only have Cementing and Melting left....
The answer is melting, I got 100% on my test.
Hope this helps!!!! :D
Please give brainliest!!!
Answer:
D
Explanation:
In the rock cycle, surface events takes place at the surface of earth. Thus,
weathering and erosion are surface events, while the subsurface events he take place in the deeper section of the earth . Examples of sub surface events are plate tectonics and mountain building or anything that takes place in the inner core of earth.
What does an atomic number represent in an atom? number of neutrons number of protons number of electrons number of protons and neutrons
Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

A block of lead displaces 50.5ml of water. The block weighs 698 g. From this
information, calculate the density of lead.
Answer:
13.82 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question we have
[tex]density = \frac{698}{50.5} \\ = 13.8217...[/tex]
We have the final answer as
13.82 g/mLHope this helps you

Would you expect manganese(II) oxide, MnO, to react more readily with HF(aq) or NaOH(aq)?
Answer:
NaOH(aq)
Explanation:
NaOH(aq) is known to precipitate Mn^2+ ions according to the following reaction; Mn^2+(aq)+2OH^−(aq)↽−−⇀Mn(OH)2(s)
Hence, manganese(II) oxide reacts more readily with NaOH(aq) under ordinary conditions precipitating the metal hydroxide solid. This is one of the characteristic reactions of Mn^2+.
