Formation of Sedimentary RocksLast Updated on Tue, 15 Mar 2016 | Geology
N^deS Sediments produced by weathering and erosion form sedimentary rocks through the process of lithification.
Real-World Reading Link Whenever you are outside, you might see pieces of broken rock, sand, and soil on the ground. What happens to this material? With one heavy rain, these pieces of broken rock, sand, and soil could be on their way to becoming part of a sedimentary rock.
Weathering and Erosion
Wherever rock is exposed at Earth's surface, it is continuously being broken down by weathering—a set of physical and chemical processes that breaks rock into smaller pieces. Sediments are small pieces of rock that are moved and deposited by water, wind, and gravity. When sediments become glued together, they form sedimentary rocks. The formation of sedimentary rocks begins when weathering and erosion produce sediments.
Weathering Weathering produces rock and mineral fragments known as sediments. These sediments range in size from huge boulders to microscopic particles. Chemical weathering occurs when the minerals in a rock are dissolved or otherwise cimicly changed. What happens to more-resistant minerals during weathering? While the less-stable minerals are chemically broken down, the more-resistant grains are broken off of the rock as smaller grains. During physical weathering, however, minerals remain chemically un changed.
Answer:
91.5 mol
Explanation:
Volume of gas = 70 L
Temperature = 25°C
Pressure = 32 atm
Moles of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
25+273.15 = 298.15 K
By putting values,
32 atm × 70 L = n ×0.0821 atm.L /mol.K × 298.15 K
2240 atm.L = n ×24.48 atm.L /mol
n = 2240 atm.L / 24.48 atm.L /mol
n = 91.5 mol
<u>Answer:</u> The wavelength of light is 
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Final energy level = 3
= Initial energy level = 6
Putting the values in above equation, we get:
Hence, the wavelength of light is
What language is that because I speak English
B. Low; very little
Explanation:
Metals such as iron, lead, copper and zinc have low specific heats. This means that it takes very little energy to change their temperature.
Specific heat is the heat required to raise the temperature of 1g of substance by 1°C.
Metals have good thermal conductivity and generally have low specific heat. This implies that their temperature can easily be raised when heated.
Some substances like water have very high specific heat. This suggests that they require more heat to raise their temperature.
