Answer:
Sedimentary rock type
Explanation:
Sedimentary rocks are directly derived from the broken particles of the pre-existing rocks. When rocks undergoes weathering, the sediments are transported from one place to another by means of agent such as wind, water and ice. These transported sediments are then deposited at a different place. With time, these sediments are compacted and lithified and forms a sedimentary rock.
The compaction process allows the sediments to stick to one another, providing the cementing materials such as silica, calcite as well as hematite. This compaction and lithification of sediments give rise to the formation of sedimentary types of rocks.
1. The behavior of rock is determined by all of the following factors EXCEPT:
a. temperature
b. pressure
c. rate at which stress is applied
d.boiling point
2. What occurs in the asthenosphere & is responsible for plate movement?
a. convection
b. vaporization
c. vaporization
d. divergence
3. Which layers make up the tabosphere?
a. inner and outer core
b. mantle
c. inner core, outer core and mantle
d. crusts and mantle
e. the tabosphere does not exist
Answer:
1. Boiling point, 2. Convection, 3. does not exist
Explanation:
The behavior of the rocks is influenced by the temperature and pressure conditions inside the earth, this also includes the rate of stress applied upon the rock mass. More the heat and pressure of rocks more will be here transformation. Convective currents that rise from the asthenosphere are responsible for the movement of plates from the source, as these forces cause the plates to rotate and break up when the gases are released from below the surface of the earth in a very sudden manner. The layers found within the earth are called core crust and mantle but no such layer atmosphere exists on or above the surface of the earth in any form what so ever.A temperature inversion occurs when ____.
Question 50 options:
Stable, cold air overlays warm air
Temperature decreases as altitude increases
Stable warm air overlays cold air
Air turbulence causes mixing between air layers
Answer:
Option (3)
Explanation:
The temperature inversion is defined as the condition where the atmospheric temperature increases with respect to height. Normally, the temperature decrease with the height. A stable warm air overlays a colder air at higher elevations, during a temperature inversion condition. This inversion of temperature can also block the pollutants that rises from the lower atmospheric layers. It is because the warm air that is present above the cooler air does not allow the trapping and merging of the substances.
Thus, the correct answer is option (3).
Final answer:
A temperature inversion occurs when warm air overlays cooler air near the surface, resulting in increased temperatures with higher altitudes, which can trap pollutants.
Explanation:
A temperature inversion occurs when a layer of warm air overlays a layer of cooler air near the earth's surface, leading to an increase in temperature with altitude, which is the opposite of the typical temperature decrease with altitude in the troposphere. Conditions that can lead to a temperature inversion include radiational cooling of the surface, lack of wind, and certain topographical features that limit air movement. Inversions can cause environmental problems by trapping pollutants in the cooler air near the surface, as the denser cool air acts like a lid over the pollutants.
Electric power is less expensive at night because:
w) more hydroelectric generation is brought on line at night.
x) there is less demand at night.
y) pollution control is less stringent at night.
z) power plants are more efficient at night.
Answer:
x) there is less demand at night
Explanation:
Electric power and it's the price is dependant on the level of demand it has, there are peak and off-peak times during the day, generally speaking during the night (between 10 pm and 7 am) electricity has lower demand.
The existence of peak times at a day is the reason why hydroelectric generation is lower at night, normally in peak off times the hydroelectric generator stores water for when the demand increases, same happens with powerplants at night not being as efficient as they are during the day when the energy is more needed. Finally, pollution control is stringent at all times of the day, its not related to the demand.
I hope you find this information useful! good luck!
Final answer:
Electric power is cheaper at night due to decreased demand, increased efficiency of power plants, and effective pumped storage systems.
Explanation:
Electric power is less expensive at night because:
There is less demand at night: During nighttime, the overall demand for electricity decreases as many industries and households are not running high-power consuming activities.
Power plants are more efficient at night: Some power plants, like hydroelectric and wind turbines, can operate more efficiently at night due to lower demand and cooler temperatures.
Pumped storage is effective: Systems with power plants having low operating costs can provide electricity at lower rates, which contributes to cheaper nighttime electricity.
Which of the following statements about observing rocks at an outcrop is true? Observing the entire outcrop does not provide important information about rock relationships and layering. Arock's texture cannot be characterized from a hand specimen; it can only be done in thin section. Clay-sized and smaller grains can be identified in the field with a hand lens. A hand specimen is a small piece of the outcrop that can be examined closely.
Answer:
A hand specimen is a small piece of the outcrop that can be examined closely.
Explanation:
True statement:
A hand specimen is a small piece of the outcrop that can be examined closely.
A rock's texture cannot be characterized from a hand specimen is false statement as rock texture can be characterized from a hand specimen.
Clay-sized and smaller grains can not be identified in the field with a hand lens as these grains are too small to be identified by hand grains.
