A legion in the Roman army consisted of about 6,000 infantrymen and 120 cavalrymen.
True
False
What was the common language spoken throughout much of the Roman Empire?
English
Greek
Hebrew
Latin
Spanish
Answer: Did all soldiers in the Roman Army actually speak Latin, or were only the commanders fluent?”
It somewhat depends on the period but, in general, yes.
This is a bit more interesting topic than you might think. One thing to understand is that the Empire was a military dictatorship. The army was a club, a gang in some sense, that ruled over the civilian population (not entirely unlike a modern gang ruling over a neighborhood and extorting money from the local businesses). Originally the army was composed exclusively of men from the city of Rome itself ruling over the conquered peoples of the lands around the Empire. Citizenship was gradually extended over the Empire but the army remained a very exclusive club. A defining characteristic of the army even in later times was that it was exclusively Latin-speaking. Though not everybody was natively Latin-speaking, to become a member of the club, you had to become a Latin speaker.
This becomes very interesting in late classical times. In the Western Roman Empire, the army came to be manned entirely by mercenary armies, mostly Germanic tribes referred to as foederati. These tribes were not natively Latin-speaking, of course, but they nevertheless used Latin (broken Latin to be sure) in their operations. In the Eastern Roman Empire, Latin was a small minority language spoken only in a few regions to the north. Nevertheless, the army still drew heavily from this group and the army remained a Latin club. This situation continued until the 6th century but then things finally reached a point where the Greek majority in the northeastern Mediterranean came to dominate and the Latin minority was pushed aside.

after water falls over land as precipitation, which path would return water most directly to the atmosphere?
After water falls over land as precipitation, Water evaporates into the air from the sea and to a much inferior magnitude from the shore. Winds transport this dampness-loaded down air, frequently excellent distances, as far as environments causing the liquid to abridge into clouds.
When water falls, any of the water soaks into the ground, moderately affecting earthward, therefore alongside, permanently seeping into ponds, streams, or straightforwardly into the sea. When the rate of precipitation surpasses the Earth's skill to consume it, the spring runoff flows over the surface into basins and streams.
Much of the water that infiltrates or flees ultimately returns to the air by way of dissolution from the soil, ponds, and streams. Some of the water that infiltrates the ground surface is fascinated by plants, that therefore release it into the air. When sleet falls in very cold districts, it grants permission to engage in a snowfield or snow.

Hurricanes are large tropical storms with heavy winds that exceed 74 miles per hour. Hurricanes produce heavy rains and may give rise to tornadoes. What is the source of the energy contained in hurricanes?.
Answer: Heat energy.
Explanation: The source of hurricanes is heat energy, which is practically fuel to the storm.
Hurricanes derive their energy from the thermal energy of ocean waters.
Hurricanes are one of nature's most powerful and destructive forces. But have you ever wondered where their power comes from?
A hurricane's formation is complicated, but it is primarily determined by three factors. To begin, you'll need warm water, ideally at least 80 degrees. The second component is moist air. Finally, converging winds are required for the formation of a hurricane.
The storm absorbs heat energy from the surface water in the same way that a straw absorbs liquid. Moisture forms in the air as a result of this.
The storm will become a hurricane if the wind conditions are favorable. The storm is powered by this heat energy. And the warmer the water is, the more moisture there is in the air. As a result, hurricanes could become larger and more powerful. Heat and energy transfer are depicted in satellite imagery.

Hurricanes are large tropical storms with heavy winds that exceed 74 miles per hour. Hurricanes produce heavy rains and may give rise to tornadoes. What is the source of the energy contained in hurricanes?.
Large tropical storms with sustained winds of more than 74 mph are called hurricanes. Tornadoes and a lot of rain are produced by thunderstorms. The thermal energy of ocean water is the source of energy for storms.
The significant latent heat of the ocean serves as a hurricane's covert energy source. It may surprise you to learn how dry the air is above tropical waters. Despite the fact that the water and the air may both be warm and quiet, evaporation is still possible since the relative humidity of the air is not 100%.
Similar to how a straw absorbs liquid, when the surface water is heated, the storm absorbs heat energy from the water. The air becomes moistened as a result. The storm can develop into a hurricane if the wind conditions are appropriate.

Water contamination occurs when pollutants contaminate water sources and render the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually contaminated by all types of pollution.
Bacteria that cause diarrhea, cholera, dysentery, typhoid, hepatitis A, and polio can be found in contaminated water. The UN estimates that each year, 297,000 children under the age of five pass away from illnesses brought on by poor hygiene, sanitary conditions, or contaminated water. From farms, factories, and towns, streams and rivers transport pollutants like chemicals, fertilizers, and heavy metals into our bays and estuaries, where they are then transported out to sea. The wind also brings in marine waste, particularly plastic, as does water from storm drains and sewage systems.

Monsoon wind is a seasonal wind that blows in the opposite direction of normal winds.
Prevailing wind is a wind that blows mainly from a single (one) general direction.Seasonal winds that blow in the opposite direction of normal winds often cause drought in the winter.Seasonal winds are variations in large-scale weather patterns that cause repetitive and predictable air movements. Many places around the world experience seasonal winds. An individual geographic location determines the name given to a specific seasonal wind as well as the underlying physical forces that propel the winds.The monsoon winds are one of the most recognized seasonal winds. Though frequently mistaken for rainstorms, monsoons are actually a type of seasonal wind. In low-latitude climates, a monsoon is a seasonal change in wind direction from winter to summer. Typically, monsoons blow from the land in the winter (known as the dry phase because the wind is composed of cool, dry air) and from the water to the land in the summer (known as the wet phase because the wind is composed of warm, moist air), causing a significant change in the patterns of precipitation and temperature in the area affected by the monsoon.Learn more about Seasonal winds, here
