Smooth air, poor visibility, fog, haze, or low clouds should be expected beneath a low-level temperature inversion layer when the relative humidity is high.

Humidity is the concentration of water vapor gift inside the air. Water vapor, the gaseous nation of water, is usually invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be a gift. Humidity relies upon the temperature and strain of the gadget or the hobby. The same amount of water vapor results in higher relative humidity in cool air than in warm air. An associated parameter is the dew point. The quantity of water vapor had to reap saturation increases because the temperature will increase. As the temperature of a parcel of air decreases it will subsequently reach the saturation point without adding or dropping water mass. The amount of water vapor contained inside a parcel of air can vary significantly. As an instance, a parcel of air near saturation may include 28 g of water per cubic meter of air at 30 °C (86 °F), however most effective eight g of water according to a cubic metre of air at eight °C (forty-six °F).

The correct answer is option B.

A normal fault scarp formed by a single earthquake looks like a curved steep slope like a river bank.

Earthquakes are high-energy seismic waves that cause a great amount of shaking of the earth and transform the outer layer of the earth's surface.

Typically, a normal fault scarp is a steeper slope, dip, or space that is created in the outer surface as a result of an earthquake.

These faults are exactly like small multiple cracks or giant trenches which appear on the lithospheric surface of the earth.

Normally, a vertical offset occurs along the normal faults. In normal fault trenches, the features of fault scarps appear to be like hanging walls.

Increasing the concentration of greenhouse gases in the earth’s atmosphere decreases the transparency of the atmosphere to infrared light.

The term "greenhouse gas" refers to a gas that creates the greenhouse effect by both absorbing and emitting thermal infrared radiation. The five main greenhouse gases in the atmosphere of Earth are ozone, carbon dioxide, methane, and water vapor. Earth's greenhouse gases hold heat in the atmosphere, warming the entire planet.

Fluorinated gases, together with naturally occurring gases including carbon dioxide, methane, nitrous oxide, and water vapor, are the main gases responsible for the greenhouse effect (which are synthetic). Greenhouse gases function as a barrier, blocking some radiations, particularly those of infrared light, from leaving the Earth, which ultimately causes an increase in the Earth's surface temperature.

Yes, the statement is true that oxygen a planet's atmosphere is smoking gun evidence for life on earth.

If there were no life on the planet, then all the oxygen would be converted into carbon dioxide - the chief component of the greenhouse effect.

Without life, there would be low levels of oxygen or an end of oxygen in the atmosphere and a resultant abundance of carbon dioxide.

Excessive levels of carbon dioxide are creating the greenhouse effect which is ultimately leading to global warming.

Moreover, the planet earth would be hotter just like venus as there is no oxygen.

Furthermore, there will be sulfur and nitrogen oxides in the atmosphere resulting in acidic rain.

If we look back into the earth's history, we see that organisms such as microbes, algae, and fungi are the ultimate producers of oxygen in the atmosphere through photosynthesis which is smoking gun evidence for life on the planet.

Answer:

Explanation:

Angle 1 = 180-77

Angle 1=103

as Angle 77 = Angle 180-Angle 1 ([corresponding angles])

And Angle 2=Angle 77 ([Vertically opposite angles])

Answer:

When a line bisects an angle, it divides the angle into two congruent angles.

Angle FGH = Angle HGI

4x - 6 = 5x - 15

x = 9

Substitute x into angles.

Angle FGH = 4(9) - 6 = 30°

Angle HGI = Angle FGH = 30°

Angle FGI = Angle FGH + Angle HGI

= 30 + 30

= 60°

You will need a minimum of three seismometers in order to locate the earthquakes.

A seismometer is a device used to gauge ground tremors brought on by explosions, volcanic eruptions, and earthquakes. In most situations, a seismograph consists of these, a timing device, and a recording device. Seismic waves are sent into space during an earthquake.

Seismographs can be used to pinpoint the epicenter of an earthquake from at least three separate locations. By turning seismic wave vibrations into electrical impulses that may be seen as seismograms on a computer screen, seismometers enable earthquake detection and monitoring. Earthquakes are studied by seismologists, who can utilize this information to pinpoint an earthquake's exact location and magnitude.

In the Northern Hemisphere, winter officially begins on December 21 and summer officially begins on June 21. (in the Southern Hemisphere).

The Tropic of Cancer (23°27′ N), the northernmost point of the Sun's vertical overhead beams, is reached on this day of the winter solstice in the Southern Hemisphere. Extreme weather and odd words to express it are characteristics of winter. At 6:12 a.m. The winter solstice, or the start of winter, occurs at approximately noon EST on Friday, December 21, when the sun crosses the Tropic of Capricorn, appearing to shine farthest south of the equator.

The only period when the quantity of sunlight and nightfall in the Northern and Southern Hemispheres is practically equal is during the equinoxes. Two equinoxes occur annually on Earth: one around March 21 and the other around September 22. The equator receives direct sunlight on March 21 and September 23. Since neither pole is oriented toward the sun in this configuration, there are equal numbers of days and nights on the entire planet. It is referred to as an equinox. The Northern Hemisphere is now experiencing a return to spring. In the Southern Hemisphere, the equinox in March signifies the beginning of fall and the equinox in September, the beginning of spring.

The longest day of the year in the Northern Hemisphere occurs on June 21; this day is known as the Summer Solstice. The length of a day in Delhi is roughly 14 hours. The latitudinal location of a site determines how much light it receives during the summer solstice in the Northern Hemisphere. The longest day of the year occurs in the hemisphere that is nearest to the sun, whereas the longest night occurs in the opposite hemisphere.

The average yield for wheat has increased 3 times in the last 60 years.

The broad range in wheat production costs across the nation was due to variations in crop yields, cropping techniques, and the costs of land, labor, and capital assets. The variety in the types of wheat farmed in the United States, each with its own production methods and related expenses, is mostly due to regional climate variances. For instance, northern wheat growers opted for spring wheat varieties that were harvested in the fall because winter wheat, which was sown in the fall for summer harvest, would perish in the cold during its winter dormancy.

Farmers in regions with plentiful rainfall were able to increase their potential output by using high amounts of fertilizer. At the opposite end of the spectrum, some places possessed lands that required expensive irrigation in order to grow a wheat harvest.

The patterns in Earth’s low cloud coverage is that, throughout the year there is a shift in the low pressure and high pressure region which is due to the changing insolation and presence of the land and ocean.

The cloud coverage tends to depend on the duration of sunshine as the location with more cloud coverage have as least exposure of sun and the least cloudy locales are seen as the sunniest ones. Thus, cloud coverage is defined as the fraction of the sky occupied by clouds as observed at a location.

So, clouds act like a blanket, by trapping heat on Earth and by also absorbing the heat which is thus released by the surface of the planet. Then heat is radiated back towards Earth, warming the lower regions of the atmosphere.

In geology, unconformities are defined as series of rock records that are formed as a result of erosion, subsidies, and uplift during the development of the earth's surface.

In general, unconformities are time gaps existing between sedimentary and igneous rocks and differentiate them from each other.

The evolution of an unconformity takes place in four steps: Deposition, deformation, erosion, and renewed deposition.
