The rate of geologic processes can happen quickly or take a long time.
Answer:
Take a long time
Explanation:
Geology is defined as a science mostly concerned with the study of the history of the earth as recorded in different rocks formations.
Geologic processes are events that occur on a geological timescale which may span across many centuries.
The four major geologic process are known to include; impact cratering, volcanism, tectonics, and erosion.

What is the unit of measure for energy? watt newtons joules meters per second
Answer:
c. Joules
Explanation:
I went over this already
Based on scientific information and records, the unit of measurement for energy is called: C. Joules.
What is energy?Energy can be defined as the ability of an object or body to do work. Thus, energy must be possessed or transferred to an object or physical body before it can be used in doing a work such as heating a system.
In Science, Joules is the standard unit of measurement for energy while Newton is the unit of measurement for force. Also, Watt is the unit of measurement for power and meters per seconds is a unit for measuring the velocity (speed) of an object.

During World War One, observation balloons were used in order to spy out enemy positions. An observation
balloon was filled with 0.50 atmospheres of Helium, 54.0 mm Hg of Nitrogen, and 0.400 atmospheres of
Hydrogen. What pressure in atmospheres was the balloon filled to?
Answer:
0.971
Explanation:
The pressure (P) in atmospheres (atm) the balloon was filled to will be
P = P1 +P2 + P3
where P1 is the pressure in atm of Helium (0.5 atm)
P2 is the pressure in atm of Nitrogen (X atm)
P3 is the pressure in atm of Hydrogen (0.4 atm)
The value of P2 provided in the question is in mmHg
To convert we have
1 atm = 760 mmHg
X atm = 54 mmHg
X = 54 × 1/760
X = 0.071 atm
Hence, P2 = 0.071 atm
Thus, from the formula earlier
P = 0.5 + 0.071 + 0.4
P = 0.971 atm

Which is warmer 10c or 30f
Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.

Which sentences describe alpha particles?
1. Alpha particles consist of two protons and two neutrons.
2. Alpha particles consist of a negatively charged electron emitted by a nucleus.
3. Alpha particles are produced during alpha decay.
4. Alpha particles are produced during beta decay.
5. Alpha particles release energy.
Answer:
1. Alpha particles consist of two protons and two neutrons.
Explanation:
Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.
AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;
Number of protons = 2
Number of neutrons = Mass Number - Atomic Number = 2

Explanation:
A 5.32 g mixture contains both lithium fluoride, LiF, and potassium fluoride, KF. If the mixture contains 3.12 g fluorine, what is the mass of the KF in the mixture?
Answer:
Explanation:
entire mixture = 5.32g
F = 3.12g --> 3.12g*(1mol/18.998g) = 0.1642mols F
Since LiF has 1mol Li to 1 mol F,
0.1642mols F* (1mol Li/1 mol F) = 0.1642mols Li
Convert into grams:
0.1642mols Li * (6.94g/1mol) =1.1397g Li
So add the masses of Li and F together:
3.12g F + 1.1397g Li = 4.2597g LiF
5.32g - 4.2597g LiF = 1.06g KF
-----
Basically what we did is convert the given mass of F to mols and since we know that there is a 1:1 mole ratio of F to L, the number of mols of F is the number of mols of Li. Change the mols of Li to grams and then add the mass of Li with given mass of F. You now have the mass of LiF. To find mass of KF, subtract mass of LiF from mass of entire mixture.

Features which are found in plant cells only are the chloroplast, large vacuole and cell wall.
Plants and animal cells consists of the following parts ; Mitochondria, cell membrane, vacuole, cytoplasm and so on. The vacuole present in animal cells are much smaller than those found in plant Cells. Hence, vacuole in animal cells are called small vacuole Plant cells also consists of cell wall, chloroplast and a large vacuole. All these are missing in animal cells.Therefore, Only plant cells have "a cell wall, chloroplasts and a large vacuole."

Describe the pattern observed in volume measurements as different masses or volumes of the unknown solid or liquid were selected. Explain why this pattern exists.
Answer:
Throughout the expansion segment below, the definition including its instance specified is defined.
Explanation:
Volume is the sum of space filled by measurement of material throughout 3 directions. The volume of either a compound is mainly determined by the amount and the process including its molecules.The larger the volume as well as strength including its solid as well as liquid, the greater the total weight.That's because the combined volume or total weight is supposed to have been significantly greater. After all, there is so much mass.

Calcium oxide is made from the thermal decomposition of calcium carbonate: CaCO3 CAO + CO2
a) Calculate the maximum mass of calcium oxide that could be formed from heating 500 g of calcium
carbonate.
Answer:
Explanation:
n CaCO3 = mass / m.wt
= 500 /( 40 + 12 + 16x 3)
= 5 mole
n CaO = 5 moles ( from the balanced equation we have 1:1 moles )
mass of CaO = nCaO X m.wt
5 x( 40 +16 )
= 280 grams
