. if you are at 10° n, how many times during the year will the sun pass precisely through your zenith?

Answer:

Tidal Pools

Explanation:

Tidal pools usually experience the most extreme seasonal variations. They are located in the intertidal zone, which is the area of the shore that is covered and uncovered by the tides. As a result, the organisms that live in tidal pools are exposed to extreme variations in temperature, salinity, and other environmental factors as the tides come in and go out. This can make life challenging for the organisms that live there and can lead to high levels of seasonal variability in the tidal pool ecosystem.

Scoria is a vesicular ejecta that is produced from mafic magma. Although pumice is also vesicular, it differs from scoria in that pumice is felsic. So the option A is correct.

Scoria is an igneous rock made up of small, spongy, glassy fragments. It is created when mafic magma (magma with a higher content of iron, magnesium, and other minerals) is ejected into the air as a result of a volcanic eruption. Pumice, on the other hand, is a felsic rock created by the explosive eruption of felsic magma (magma with a higher content of silica).

Scoria is usually darker in color than pumice, and it has a denser texture, while pumice is generally much lighter and less dense. The difference in composition between scoria and pumice is due to the different types of magma they come from.

Mafic lava is generally much thinner and flows more easily than felsic lava, which is thicker and tends to fragment explosively. This fragmentation produces the vesicles that give scoria and pumice their unique characteristics. So the option A is correct.

Note that the characteristics in the Cold Climate Zone are matched accordingly:

Note that an ice cap is a permanent feature characterized by extremely cold temperatures, while nonpermanent ice, such as glaciers and frozen lakes, undergo freeze-thaw cycles due to changes in temperature.

Highlands, which can be found at higher elevations near the equator, may have ice due to cooler temperatures even in warmer regions.

Sewage treatment, also known as wastewater treatment, is the procedure that causes the majority of the organic content in sewage to break down biologically.

Particularly, biological treatment refers to the step in sewage treatment that causes organic materials in sewage to decompose. This entails using microorganisms like bacteria and fungi to break down the organic materials in the sewage and transform it into simpler molecules like water, carbon dioxide, and other harmless elements. Biological treatment is often carried out at sizable treatment facilities that use a number of tanks and procedures to clean the wastewater so that it can be released back into the environment or used for a variety of other reasons.

Polders  is a land that has been reclaimed by the sea by building levees, sea walls, canals, and using hydraulic pumps such as a windmill

A portion of land that has been recovered from the sea or from inland water is referred to as a "polder," which is a Dutch word that originally meant silted-up land or an earthen wall. It is used to a lake that has been pumped dry, a reclaimed coastal area, or a marsh that has been drained.

The muskrat, which is recognized for this behavior and is persecuted in several European nations as a result, is notorious for digging holes in the barrier, allowing water to enter the building.

The rock cycle is a continuous process that describes how rocks are transformed from one type to another over time. The rock cycle involves three main types of rock: igneous, sedimentary, and metamorphic.

The following process occurs repeatedly during the rock cycle:

Weathering and erosion: The disintegration and erosion of existing rocks occurs as a result of exposure to weather, water, and other natural processes.

The eroded elements settle and are deposited in a new area, where they are crushed and cemented together to form sedimentary rocks.

Heat, pressure, and chemical reactions can convert existing sedimentary or igneous rocks into metamorphic rocks.

Melting and solidification: When exposed to extreme temperatures and pressures, rocks can melt and create magma. Igneous rocks are formed when magma cools and solidifies

Any extinct and living creatures that are linked to contemporary humans more closely than to chimpanzees are collectively referred to as "hominins."

Australopithecus and early members of the genus Homo were among the several hominid species that lived throughout the Pliocene epoch, which lasted from roughly 5.3 to 2.6 million years ago. These animals possessed a variety of physical traits, including tiny brain sizes, bipedal movement, and modifications for eating hard meals. Although scholars disagree on the precise relationships and classifications of these Pliocene hominin species, they are widely thought to be related to humans because they have many of the same anatomical and behavioural characteristics that set humans apart from other primates. Because they are significant evolutionary ancestors of modern humans and are a part of the larger human evolutionary tree, all of the fossil taxa from the Pliocene examined in this module are referred to as hominins.

The Doppler effect is a phenomenon that occurs when there is relative motion between a source of waves and an observer. It can be observed in both light and sound waves and explains the changes in wavelength (or frequency) that are detected by an observer.

In the case of sound waves, when a sound source is moving towards an observer, the sound waves are compressed and the frequency appears to be higher than the actual frequency of the sound.

In the case of light waves, the Doppler effect is responsible for shifts in the wavelength of light that are observed from stars and galaxies. When a star or galaxy is moving towards the Earth, the light waves are compressed and the wavelength appears to be shorter, shifting towards the blue end of the spectrum (known as a blue shift).

Overall, the Doppler effect can be used to explain changes in wavelength (or frequency) in both light and sound waves, and it is an important phenomenon for understanding the motion of objects in our universe.
