We know that the organisms whose shell (or test) could eventually yield rocks like chalk or diatomites or radiolarites exist and can be common in shallow ocean waters. Still, we rarely see these rocks forming in shallow ocean waters. Why is that?
because their productivity is very low
because they are destroyed by the waves
because they are destroyed by the acidity of ocean waters
because they are diluted by other sediments
all of these
Answers
The shells of the organisms are destroyed by the acidity of ocean waters. When the ocean water becomes more acidic the shell of the organisms dissolves faster. For animals like corals, sea urchins, sea snails, and oysters to survive, they need to use more energy to either thicken or repair their damaged shells and exoskeletons.
When calcium carbonate has a very low solubility in neutral pH ocean water. However, as the solution's acidity rises, calcium carbonate's solubility rises as well, dissolving the calcium carbonate in the solid shell. This makes the shell dissolve.

How do pressure and temperature change from earth's surface to the top of the thermosphere?
Answers
Pressure is lower at higher altitudes; temperature is highest in the outer atmosphere.
What Is the Thermosphere?
The thermosphere, the second-highest layer of the atmosphere, stretches from the mesopause, which divides it from the mesosphere, at an altitude of roughly 260,000 feet, up to the thermopause, which is located at an altitude between 1,600,000 and 3,300,000 feet.
The thermosphere's temperature rises to maximum values that are greatly influenced by the level of solar activity. Vertical exchanges related to dynamical mixing become unimportant, whereas molecular diffusion emerges as a prominent process that results in the gravitational separation of species according to their molecular or atomic weight.

How does where and how people live impact global cultural, political, and economic patterns?

We find that location and climate have a significant influence on income levels as well as the growth of income. These effects manifest themselves in a variety of ways, including the cost of transportation, the illness load, and agricultural production. Additionally, it seems that location has a role in the decision-making process behind economic policy itself.

These exchanges have made the globe a more linked and interdependent place, and they continue to do so.
In conclusion, In this study, we discover that both starting income and income growth are significantly affected by geographic location and weather conditions. The price of transportation, the number of sick people, and the amount of food produced are only a few of the ways in which these consequences show themselves.

irrigation methods in manipur
Answers
The region primarily relies on traditional irrigation practices, although modern techniques are gradually being adopted.
Here are a few common irrigation methods used in Manipur:
Diversion channels: This method involves diverting water from rivers or streams into irrigation channels that distribute water to the fields. Diversion channels are constructed to capture and channelize water towards agricultural areas, allowing farmers to control the flow and distribution of water.Tanks and ponds: Manipur has a network of natural and artificial tanks and ponds that serve as water storage reservoirs. These water bodies are used for irrigation by releasing water into the fields through canals or channels. Tanks and ponds play a crucial role in providing water during dry periods or seasonal variations in rainfall.Lift irrigation: In areas where the water source is at a lower level compared to the fields, lift irrigation is employed. This method involves using pumps or other mechanical means to lift water from rivers, streams, or wells and then distributing it through pipelines or channels to the fields that require irrigation.Sprinkler irrigation: Sprinkler irrigation is a modern technique gaining popularity in Manipur. It involves using sprinklers that distribute water over the fields in a spray pattern, similar to rainfall. Sprinkler systems help conserve water by reducing evaporation and providing more precise water application. This method is suitable for a variety of crops and terrains.Drip irrigation: Drip irrigation is another modern method becoming increasingly adopted in Manipur. It involves delivering water directly to the plant roots through a network of pipes and emitters. This method is efficient in water usage as it minimizes evaporation and provides targeted irrigation. Drip irrigation is particularly beneficial for water-intensive crops and areas with limited water availability.For such more question on irrigation:

After ingesting ________ like thiamin or riboflavin, the excess is usually excreted in the urine.
Answers
After ingesting vitamins like thiamin or riboflavin, the excess is usually excreted in the urine.
Thiamin and riboflavin are two essential vitamins that are necessary for the body to function properly. They are water-soluble vitamins, meaning that they are not stored in the body and need to be replenished regularly.
After ingesting thiamin or riboflavin, the excess is usually excreted in the urine. In general, the body is able to detect and excrete unneeded vitamins within a few hours. This is beneficial because if the body was unable to do so, it could accumulate large amounts of water-soluble vitamins and cause health problems.
The body is usually able to regulate the amount of thiamin and riboflavin it needs and will excrete any excess amounts. It is important to note that if the body is deficient in either vitamin, it may not excrete any excess. In this case, supplementation may be necessary.

In sites near a subduction zone, extension can occur in all of these locations: a) in front of the arc, b) within the arc, and c) behind the arc. So, the correct answer is d) all of these.
Extension can occur in all of these sites near a subduction zone: in front of the arc, within the arc, and behind the arc. This is because the subduction of an oceanic plate beneath a continental plate can cause a variety of tectonic forces that can lead to extensional deformation in different areas around the subduction zone. For example, the subducting plate can pull on the overriding plate and create extension in the area in front of the arc, while the release of pressure as the plate sinks can lead to extension within the arc and behind the arc.

A fissure is a hole in the Earth's surface that is long and narrow. The word "cleft" or "crack" is derived from the Latin word fissura. In the crust of the Earth, on ice sheets and glaciers, and on volcanoes, fissures appear.
An aperture or long, thin fracture in the Earth's crust is referred to as a ground fissure or an earth fissure. Ground fissures can develop due to geological faulting, earthquakes, or human activity like oil mining and groundwater pumping.
They can also develop spontaneously. Ground fissures can grow and erode by torrential rain after they have already formed. They can cause harm to property and infrastructure, including roads, underground pipes, canals, and dams, as well as pose a risk to humans and cattle who reside on the impacted surfaces.

Boron has two stable isotopes 10 b and 11 b . from this information, predict how the radioactive isotope 13 b will decay
Answers
Boron has two stable isotopes 10 B and 11 B, which means that they do not undergo any radioactive decay. However, the radioactive isotope 13 B, which has an excess of neutrons, is expected to undergo beta decay.
In beta decay, a neutron inside the nucleus transforms into a proton and emits an electron and a neutrino. This transforms the nucleus into a different element while conserving the total number of protons and neutrons. Therefore, the 13 B isotope will decay into a new isotope of carbon, with 6 protons and 7 neutrons. The process can be represented as follows:
13 B → 14 C + e- + ν
Overall, predicting the decay of radioactive isotopes is important in fields such as nuclear physics, medicine, and geology, among others.
