Answer:
Horizontal lines that represent different climate zones are called latitude.
Explanation:
Latitude is the distance that exists between a point on the Earth's surface to the equator, counted by the degrees of its meridian. That is, it is the distance, measured in degrees, that exists between any parallel and the line of the Equator. The latitude of a point is measured to the North or South of the zero parallel and its value can vary between 0 ° from the equator to 90 ° N from the North pole or 90 ° from the South pole.
Climate is related to latitude because it sets the amount of solar energy that a given region or place receives. Places located at high latitudes (far from the Ecuador) receive less sunlight than places located at low latitudes (near the Equator). Thus, cities distant from the equator and close to the poles have a cold climate, while at low altitudes there are high temperatures and a hot or tropical climate.
Answer:
10 neutrons
Explanation:
The mass of is made up of the total protons and neutrons in an atom.
Each particle has a mass of 1 amu (atomic mass unit).
All fluorine atoms have 9 protons.
If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).
This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).
If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).
Answer:
C. Degree of ionization
Explanation:
The strength of an acid or a base is determined by how many H+/H3O+ or OH- ions are dissociated in solution. Therefore, it's describing the degree of ionization.
Example: HCl is a strong acid because in water it will pretty much 100% dissociate into H+ and Cl- ions.
<em>"Sedimentary rocks are formed by the pressure over millions of years of organic material, inorganic material, sediment of course , and earth piling up over itself. Metamorphic rock and igneous rock originate either below the surface where plants lived and creatures roamed, or the heat from volcanic activity transformed everything. Sedimentary rock formation is the only geologic activity that permits and allows organic material preservation and hence fossil formation." </em>- <u>Charles Snider, Co-Founder of American Geode (on Quora.com)</u>
