How are rocks identified?

The rise in temperature with depth in the Earth's crust is known as the geothermal gradient. Within the first 3 to 5 kilometers (2 to 3 miles) of the Earth's surface, a typical geothermal gradient in normal continental crust is approximately 25°C/km.

The gradient varies between the near surface and 400 ft (122 m), depending on how the atmosphere and moving ground water affect it. Temperature rises with depth almost usually below that zone.

It suggests that the Earth's surface is receiving heat from the planet's warm center. For every kilometer of depth, the temperature rises by about 25°C on average.

The earthquake's magnitude and intensity both tell you how severe an earthquake may be. They are different because "The intensity of an earthquake tells you how much damage has been caused, while the magnitude tells you how much energy has been released from the earthquake".

A abrupt release of energy in the Earth's lithosphere that results in seismic waves causes an earthquake, which is the shaking of the planet's surface. Earthquakes can range in strength from those that are so small that no one can feel them to those that are so powerful that they upend entire cities and send people and objects flying.

Hence, "The intensity of an earthquake tells you how much damage has been caused, while the magnitude tells you how much energy has been released from the earthquake", so option A is the correct answer.

lead is extracted from uranium to create lead ore. A system might go through a geological process that removes lead, leaving the resultant system devoid of uranium.

Rocks are frequently dated using lead isotopes, which offer some of the best proof of the Earth's age. The activities producing lead isotopes must satisfy all four requirements of a natural clock—an irreversible process, a uniform rate, a starting condition, and a final condition—in order to be utilised as a natural clock to determine the age of the world. This approach ultimately influenced the creation of isochrons, which plot two isotopes against one another to determine the age of the mineral or rock. 

Scientists can establish how long the parent isotope has existed by comparing the relative levels of the two isotopes and understanding the rate of decay.

Runoff occurs over a shorter time after urbanization.

Under natural conditions, runoff velocities are lower than in built-up areas and runoff occurs over a longer period of time. Also, the pre-development peak runoff rate is much lower than the post-development peak runoff rate due to attenuation and absorption by soil and vegetation.

Impermeable surfaces with urbanization reduce infiltration, increase surface runoff, and alter the pathways by which water reaches urban streams. Temperature, wind speed and humidity are the main meteorological factors affecting runoff. They affect the rate of evaporation and transpiration, thus affecting soil moisture content and infiltration rates, and ultimately runoff.

A water supply system provides services essential to the operation of industrialized society as well as essential for emergency preparedness and post-disaster recovery. It transports water from sources to customers (e.g., earthquakes). A water distribution system is a component of the water supply network that transports potable water from a centralized treatment facility or wells to consumers to meet their needs for household use, business use, industrial use, and firefighting. The majority of the water in urban and suburban areas is piped in from a central water supply.

The area of a rectangle is 424242 square millimeters. The length is 777 millimeters. The perimeter of the rectangle is 2646 millimeters.

In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. Equiangular means that each of its angles is identical, so it can also be defined as an equiangular rectangle. Or a parallelogram containing a right angle. A rectangle with four equal sides is a square.

Area of rectangle = Length × Breadth

Perimeter of rectangle = 2 (length + breadth)

A rectangle is a quadrilateral with all equal angles, i.e. real angles. Rectangles have equal angles as well as equal sides. So a square is a special case of a rectangle. In other words, rectangles are sometimes squares (but all sides are the same). So we can say that a square is a special kind of rectangle. All sides have the same period. Therefore, all squares are rectangles because they are quadrilaterals with all four corners and right angles. Therefore, not all rectangles are squares. To be square, the sides must be the same length.

Intensity of solar radiation = 250 watt/m²

                                           = 250 Js⁻¹/m²

Thickness of ice coverage = 2m

Ice coverage to be melt = 14 million km² - 4 million km²

                                        = 10 million km²

                                        = 10 × 10,00,000 km²

                                       = 10⁷ km²

                                       = 10⁷ × 10⁶m

                                       = 10¹³m

Heat reaches to surface per second = 250 Js⁻¹/m² × 10¹³m

                                                             = 2.5 × 10¹⁵ J/s

Now,

Total volume of ice = 10¹³ m² × 2m

                                = 2 × 10¹³ m³

Latent heat of ice = 3.33 × 10⁵J/Kg

Density of ice = 917 kg/m³

Total mass of ice = 917 × 2 × 10¹³

                            = 1834 × 10¹³kg

∴Heat required to melt whole ice coverage = Mass × Latent Heat

                                                                   = 1834 × 10¹³kg × 3.33 × 10⁵J/Kg

                                                                  = 6.11 × 10²¹ J

Total time taken to melt whole ice =  6.11 × 10²¹ J / 2.5 × 10¹⁵ J/s

                                                         = 2.44 × 10⁶s

Since, 1 Day = 86400s

∴ 2.44 × 10⁶s = 2440000/86400 Days
