Moons rises in the West as seen from its primary planet is d. Ganymede.

Ganymede, a moon of Jupiter, possesses a unique characteristic among the moons in our solar system. It is the sole moon that appears to rise in the west when observed from its parent planet.

This peculiarity is a consequence of Ganymede's orbital motion and the rotational dynamics between Jupiter and the moon. While most moons rise in the east due to their prograde orbits, Ganymede's opposite motion causes it to rise in the west.

This intriguing phenomenon sets Ganymede apart and adds to the allure and scientific interest surrounding this largest moon in our solar system.

Therefore, the correct answer is d. Ganymede

The monsoon season affects life in both the city and the country differently. The following are the differences between city life and country life during the monsoon season:

City Life: During the monsoon season, the streets of the city are frequently waterlogged. As a result, it becomes difficult for people to go about their daily routine. Traffic congestion becomes a daily issue as well. Due to excessive rainfall, there is also a risk of flash flooding, which can cause accidents and damage to property.

The chances of getting ill are also high due to the presence of stagnant water. Country Life: The monsoon season is essential for farmers in rural areas. They plant their crops during this time, and the heavy rain helps them grow. However, the heavy rainfall also leads to waterlogging, making it difficult for people to navigate around.

As a result, people in rural areas are often stuck indoors during the monsoon season. However, villagers are generally more equipped to handle the monsoon season since they have been dealing with it for generations. The countryside is also filled with lush greenery during the monsoon season, making it a picturesque view to look at.

A planet is a celestial body that orbits around a star, typically composed of rock, gas, or a combination of both. It is one of the fundamental components of a solar system. Planets are held in place by gravitational forces and follow elliptical paths around their parent star. They are characterized by their spherical shape, achieved through self-gravity, and are generally larger than asteroids or comets.

Planets can be classified into two main types: terrestrial planets, which are small and rocky like Earth, and gas giants, which are much larger and predominantly composed of gases like Jupiter and Saturn. Some planets may have moons orbiting around them, adding to their satellite systems.

The temporal pattern of CFCs differs from other greenhouse gases due to the impact of the Montreal Protocol on CFC emissions.

Among the four greenhouse gases, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (CFCs), only CFCs are no longer increasing in the atmosphere.

This is because an international agreement, the Montreal Protocol, effectively limited CFC emissions.

Why do cfcs follow a different temporal pattern than the other greenhouse gases?

Hence, of the greenhouse gases, only CFCs are no longer increasing in the atmosphere, having plateaued in the 1990s.

The temporal patterns of the other greenhouse gases are not influenced by such international agreements.

CFCs were once widely used in refrigeration, air conditioning, solvents, and aerosol sprays. CFCs were determined to be responsible for ozone depletion in the atmosphere.

Hence, an international agreement, the Montreal Protocol, was signed in 1987, which aimed to phase out CFC production and use.

It was successful in reducing CFC emissions and effectively limiting their concentration in the atmosphere.

Thus, the temporal pattern of CFCs differs from other greenhouse gases due to the impact of the Montreal Protocol on CFC emissions.

The weather condition that is most dangerous in terms of heat exposure is calm air with high humidity. This is because high humidity makes it harder for sweat to evaporate from the skin, which is the body's natural cooling mechanism. Option C.

When sweat does not evaporate, it means that the body cannot regulate its internal temperature, leading to heat exhaustion or even heatstroke.

Windy conditions, whether with high or low humidity, can help evaporate sweat faster, allowing the body to cool down more efficiently. However, it is important to note that extremely windy conditions can also lead to dehydration and further exacerbate heat-related illnesses.

Therefore, it is crucial to take necessary precautions such as staying hydrated, wearing light and breathable clothing, and avoiding prolonged exposure to the sun during hot and humid weather conditions.

Additionally, it is important to pay attention to any signs of heat exhaustion or heatstroke, such as dizziness, nausea, headache, or a rapid heartbeat, and seek medical attention if necessary.

The zone where accumulation balances ablation is known as the equilibrium line.

The equilibrium line is an imaginary line in a glacier or ice sheet where the net annual balance of the ice is zero. It separates the accumulation zone from the ablation zone. The area above the equilibrium line receives more snow than it loses due to melting, while the area below the equilibrium line loses more ice due to melting than it gains from snow accumulation. The equilibrium line is also known as the "firn line" or the "nival line."

The equilibrium line is the line that separates the areas of accumulation and ablation. Temperature, precipitation, and the surrounding landscape all play a role in determining the equilibrium line's elevation. The equilibrium line and the glacier margin would not change if the climate remained the same.

This statement refers to the rotation period of the Earth, which is slightly less than 24 hours. The time it takes for the Earth to complete one full rotation on its axis, known as a solar day or a mean solar day, is approximately 23 hours, 56 minutes, and 4 seconds. This duration is often referred to as the sidereal day.

This difference is because while the Earth rotates on its axis, it also orbits around the Sun. As a result, by the time the Earth completes one full rotation, it has to turn a little bit more to align with the Sun for another day to begin. To account for this, we have standardized the concept of a day as 24 hours, divided into 60 minutes and 60 seconds each. This system allows for convenience and simplifies our daily lives, even though it doesn't precisely align with the Earth's actual rotation period. However, for specific scientific and astronomical calculations, the more accurate measure of 23 hours, 56 minutes, and 4 seconds accounts for the Earth's rotation relative to distant stars, known as a sidereal day.

Whenever dregs are conveyed to the sea, these residue are modified and moved by disintegration processes.Through the effects of erosion and the remobilization of sediments, storm activities, in particular, have the potential to influence local patterns of sea level.

The transportation process typically leaves behind the coarser sediment. As a result, fine-grained sediment is typically found further from its source than coarse sediment. The manner in which sediment was transported and deposited is determined by clues it leaves behind.

When sediment moves from one location to another, what happens to it?

Through erosion, sediment moves from one location to another. The transportation and removal of rock or soil is known as erosion. Sediment can be moved by erosion through wind, ice, or water.
