The correct option is heavy rainfall. This is not a contributing factor that would result to the poor air pollution in Los Angeles.
When there are elements in the atmosphere that are dangerous to human health or the health of other living things, or that impair the climate or materials, it causes air pollution, which is the contamination of the air as a result. Humans are susceptible to air pollution-related illnesses, allergies, and even death. Other living things, such as animals and food crops, are also at risk, and the built environment or the natural environment may also be harmed. Human activities and natural events both have the potential to generate air pollution. Poor air quality has wide-ranging consequences on human health, but it primarily has an impact on the cardiovascular and respiratory systems of the body.

Geologists know that potassium-40 decays to argon-40, with a half-life of 1. 3 billion years. If an analysis of a feldspar crystal in a sample of granite shows that 75 percent of the potassium-40 atoms have decayed to form argon-40, what is the age of the granite? the granite sample is years old.
The granite specimen dates back 2.6 billion years.
What components compose granite?Granite is a plutonic rock with a light tint that is mostly present in mountainous areas of the crustal. It consists of coarse quartz grains (10–50%), sodium feldspar, and potassium feldspar. These minerals make up about 80% of the rock's composition.
Briefing :
Given ,As we know that the radioactive decays follow the first order kinetics.
First we have to calculate the rate constant.
Formula used : [tex]t\frac{1}{2}[/tex] = [tex]\frac{0.693}{k}[/tex]
[tex]1.3 billion years[/tex] = [tex]\frac{0.693}{k}[/tex]
[tex]k = 0.533 ( billion years )^{-1}[/tex]
Now we have to calculate the age of the sample of granite.
The expression for rate law for first order kinetics is given by :
[tex]k = \frac{2.303}{t}[/tex] [tex]log \frac{a}{a-x}[/tex]
where,
k = rate constant = 0.533
t = time taken for decay process = ?
a = initial amount of the reactant = 100 g
a - x = amount left after decay process = 100 - 75 = 25 g
Putting values in above equation, we get the age of the sample of granite.
[tex]0.533 = \frac{2.303}{t} log \frac{100}{25}[/tex]
t = 2.6 billion years
Therefore, the age of the sample of granite is, 2.6 billion years

As the water temperature increases, the solubility of gases in water decreases, so the oceans release carbon dioxide. This has a bad/negative impact
Oceans as carbon emittersThe impact of global warming is increasing the temperature of sea water which results in the ability of sea water to absorb carbon dioxide gas to decrease. Carbon dioxide gas has a solubility level that is twice as great in cold water as compared to warm water. The rates of photosynthesis and respiration are also highly dependent on temperature.
At relatively high temperatures, the rate of photosynthesis and respiration both increase, but the rate of respiration increases faster than the rate of photosynthesis so that the release of carbon dioxide gas becomes greater than its use and causes the sea to become a net carbon source.

geologists use a number of terms to describe the ways in which the oceans interact with land. identify the following examples by labeling the image.
The term used by geologists to discuss sea-land interactions is an estuary, swampy delta, coastal plains, Uplifted terrace, and sand dunes.
Discuss the terms in detail;
1. Estuary: A place where a freshwater river or stream meets the ocean is called an estuary. In estuaries, brackish water is created when a freshwater river and a salty ocean mingle. Although not as salty as the ocean, brackish water has some saltiness. Other names for an estuary include a bay, lagoon, sound, or slough.
2. Swampy Delta: A delta forms when a river empties into an ocean, sea, desert, lake, or simply into a bog. The main channel of this phenomenon splits into numerous streams, or distributaries Deltaic wetlands have a unique water balance that sets them apart from typical river basins, reservoirs, and lakes.
3. Uplifted Terrace: Any relatively flat area of marine origin that is bordered by a steeper ascending slope on one side and a steeper descending slope on the other is referred to as a marine terrace.
4. Sand dune: A dune is a sand mound that the wind creates, typically along a beach or in a desert. Sand accumulates in dunes when the wind drives it into a protected region behind a barrier.

The true explanation for mountain-valley breezes is that during the day, the valley air quickly warms and flows upslope, while at night, the mountain air quickly cools and descends into the valley.
When the valley bottom warms up during the day, it should be observed that the warm air will then rise to the surrounding mountain slopes, creating a valley breeze. The cooler, denser air will then glide down the slopes during the night and settle in the valley, creating the mountain breeze.

The ground shakes during an earthquake because of which type of waves? a. ocean waves b. permanent waves c. seismic waves d. sine waves
The ground shakes during an earthquake because of (c) seismic waves
When an earthquake occurs shockwaves of energy, called seismic waves, are released from the earthquake focus. They shake the Earth and temporarily turn soft deposits, such as clay, into jelly
Seismic waves are caused by the sudden movement of materials within the Earth, such as slip along a fault during an earthquake. Volcanic eruptions, explosions, landslides, avalanches, and even rushing rivers can also cause seismic waves.
Seismic waves are usually generated by movements of the Earth’s tectonic plates but may also be caused by explosions, volcanoes and landslides. Seismologists use seismographs to record the amount of time it takes seismic waves to travel through different layers of the Earth. As the waves travel through different densities and stiffness, the waves can be refracted and reflected. Because of the different behavior of waves in different materials, seismologists can deduce the type of material the waves are travelling through.
There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.
P-waves
P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth.
S-waves
S-waves, also known as secondary waves, shear waves or shaking waves, are transverse waves that travel slower than P-waves
Surface waves

to find the altitude of these satellites above the earth's surface requires the use of the law of universal gravitation and Newton's second law.
as newton laws
F = ma
where, F is force, M is mass, and a is acceleration
and law of universal gravitation is

v = d/t
where d is distance, and t is time
A complete orbit with a time (T) called the period circumnavigates the distance.
while distance of satellite is
d = 2πr
we can combile with velocity formula so,

Convert to SI units. time in second
T = 1 day (24 hours / 1 day) (3600 seconds / 1 hour)
T = 86400 seconds
