The time interval between the first P and S - wave arrivals is a direct measure of the distance from a seismic receiving station to the focus of a distant earthquake. The P wave, also known as the Primary wave or compressional wave, is a longitudinal wave and the fastest wave, with a speed of ±6 km/sec. Then the S wave usually called the second wave or shear wave is a transverse wave; moving at a speed of ±4 km/sec.

An earthquake is a shaking that is felt on the surface of the earth due to the sudden withdrawal of energy from within which creates seismic waves. Earthquakes can be recorded by an instrument called a seismograph. Seismographs produce digital graphic recordings of ground motions caused by seismic waves. The digital recording is called a seismogram.

Explanation:

The study of geological events would help predict natural calamities and help be prepared for them which would be able to save the public from diastrophic consequences.

What are geological events?

A geological event is a dynamic, diverse, and temporally distributed occurrence in Earth history that alters the Earth system and results in the production of geological strata. a clearly defined occurrence in which one or more geological processes alter geological entities. Major geological occurrences are caused by plate tectonics when portions of the Earth's crust clash, drift apart, or glide past one another. The kind of plate boundary affects the events' nature. In addition to their rapid start, geologic dangers frequently have widespread effects. Millions of square kilometres can be damaged by earthquakes, and tsunamis can span the whole ocean and wreak significant damage thousands of kilometers from their point of origin.

Hence, study of geological events would help us predict and be prepared for these events.

The sea-floor spreading means a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while the rifts occurs where there is splitting apart of a single tectonic plate into two or more tectonic plates separated by divergent plate boundaries

In geography, a seafloor spreading means a natural geologic process in which tectonic plates (large slabs of Earth's lithosphere) split apart from each other. The activities of seafloor spreading and other tectonic activity processes are the result of mantle convection as the mantle convection is the slow and churning motion of Earth’s mantle. The mantle convection currents carry heat from the lower mantle and core to the lithosphere and also “recycle” lithospheric materials back to the mantle.

Most time, the seafloor spreading occurs at the divergent plate boundaries. So, as the tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. This led to bubbled-up magma which is cooled by frigid seawater to form igneous rock, this rock (basalt) becomes a new part of Earth’s crust known as Mid-Ocean Ridge.

A population of beetles changing from yellow to brown and surviving better is an example of Natural Selection.

What is Natural Selection?

Natural selection is the variation in individual survival and procreation brought on by phenotypic variances. The evolution of a population's heritable features across generations is a fundamental mechanism of evolution. The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others.

Hence, A population of beetles changing from yellow to brown and surviving better is an example of Natural Selection because in an environment where more predators would feast on more green beetles than brown, this trait had a better chance of surviving.

El Niño is the global weather phenomenon characterized by unusually warm ocean temperatures in the equatorial pacific.

In contrast to La Nina, which is defined by extremely cold ocean temperatures in the Equatorial Pacific, El Nino is characterised by unusually warm ocean temperatures. El Nino is an ocean-atmosphere system oscillation in the tropical Pacific that has significant effects on weather globally.

Among these effects are greater rainfall in Peru and the southern US, which has led to severe flooding, and drought in the West Pacific, which is occasionally linked to catastrophic brush fires in Australia. For the forecasting of short-term climate fluctuations (a few months to a year), observations of the tropical Pacific are thought to be crucial.

The width, depth, and velocity of the stream often rise along with the discharge. Position in the stream channel, abnormalities in the stream channel brought on by resistive rock, and stream gradient all affect a stream's velocity. Water near channel edges is slowed by friction.

Flooding happens when a river's discharge exceeds the volume of its channel, causing the river to overflow into the floodplain, the region next to the channel. Several things can cause the discharge to increase. The most frequent reason for floods is heavy rain. Long periods of rain cause the soil to get saturated and lose its ability to retain water, increasing surface drainage. Floods and higher discharge levels will result from rainwater entering the river much more quickly than it would if the land weren't saturated.

Subduction zones occur when one tectonic plate moves underneath another. The denser oceanic plate sinks beneath the lighter continental plate, causing the two plates to grind against each other. This can lead to the formation of mountains and volcanoes.

Subduction is the geological process where the collision of two tectonic plates at the convergent boundary leads to the denser plate sinking deeper into the mantle.

The zone where this process takes place is referred to as the subduction zone.

Usually, this process takes place at the convergent boundary of an oceanic and a continental tectonic plate. The oceanic plate being the denser of the two as well as the asthenosphere below sinks into the upper mantle.

The oceanic plate, coming in contact with the hot mantle starts to melt. This leads to magma rising up through the fissures and cracks which leads to volcanic eruptions. The lava (magma on the surface) cools down when coming in contact with the cool atmosphere.

Thus, when subduction takes place at the convergent boundary of an oceanic and a continental tectonic plate, the continental crust gets created while the oceanic crust is destroyed.

When gases in Earth's atmosphere capture the heat from the Sun, the process is known as the greenhouse effect. Earth becomes significantly warmer as a result of this process than it would be otherwise. One of the factors that makes Earth a nice place to live is the greenhouse effect.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is released during the burning of fossil fuels. Human-made actions are referred to as anthropogenic actions, and the release of CO2 is one such anthropogenic action that contributes to the current enhanced greenhouse effect.

Global warming is the gradual warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900), and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.
