Broad and shallow outflow channels curve around obstacles like craters. They seem to have been caused by unexpected floods. Valley networks mimic drainage patterns and imply long-distance water movement, indicate that there was significant water erosion on Mars.
Currently, there may be very little liquid water on the surface of Mars, just evidence of dissolved atmospheric moisture and thin coatings, which are hostile settings for any known life. The idea that water existed on Mars dates back hundreds of years before the space age. Early telescopic viewers correctly inferred that the presence of clouds and white polar caps indicated the existence of water.
Astronomer William Herschel stated in 1784 that these discoveries, along with the knowledge that Mars had a 24-hour day, likely provided its people with "a position in many respects comparable to ours." The narrative shifted to portray Mars as a "dying" planet with scant water since the existence of seas was no longer acknowledged. The dark regions, which were seen to shift periodically, were formerly believed to represent large expanses of vegetation.

How did the US computer ENIAC help the war effect?
ENIAC computer was created as a tool to assist artillerymen in calculating shell trajectories during the height of World War II.
Despite starting to be built a year before D-Day, the computer wasn't turned on until November 1945, by which time the American Army's artillery had stopped firing. However, once the Cold War got underway, the military continued to utilize ENIAC extensively. The first hydrogen bomb's 17,468 vacuum tubes were put to use by the machine's designers, who need a means to evaluate the viability of their early ideas.
One of the first computers ever created was the ENIAC (Electronic Numerical Integrator and Computer). The Ballistic Research Laboratory of the United States Army largely used ENIAC to compute artillery firing tables. On December 10, 1945, the computer went into operation. A trajectory might be calculated by ENIAC in 30 seconds as opposed to 20 hours by a person.

Hope it Helps!______ is caused by deforestation, overgrazing, and overworking the soil Group of answer choices desertification depletion of aquifers salinization monoculture
Desertification is caused by deforestation, overgrazing, and overworking the soil.
Desertification is an environmental process in which dry, arid areas of land become increasingly uninhabitable and unable to support plant and animal life. This process is caused by a variety of factors, including deforestation, overgrazing, and overworking the soil.
Deforestation is the removal of trees and other vegetation for various purposes, such as to create space for agriculture and urban development. Without trees, the soil is left exposed to the elements and is unable to retain moisture. This leads to the soil becoming dry and barren, creating the perfect conditions for desertification.
Overgrazing is the practice of having too many animals grazing on a given area of land. This can cause the land to become overly depleted of vegetation, which can lead to desertification. Overgrazing can also lead to soil erosion and loss of fertility, as the animals trample and consume the vegetation that would otherwise help retain moisture.
Overworking the soil is the practice of tilling the soil too often or too deeply. This can lead to the depletion of organic matter and soil organisms, which are essential for maintaining soil health. Without the organic matter and soil organisms, the soil is unable to retain moisture, leading to desertification.
All of these practices can have devastating effects on the environment and can lead to desertification. Deforestation, overgrazing, and overworking the soil can all contribute to the depletion of aquifers, salinization, and monoculture. These effects can render entire regions uninhabitable, making it difficult for plants, animals, and humans to survive. Therefore, it is important to take steps to protect our environment and prevent the effects of desertification.

rocks from which source would most likely contain the highest percentage of iron-bearing minerals?
Ocean floor would most likely contain the highest percentage of iron bearing minerals.
Ocean-dwelling organisms like cyanobacteria produce oxygen, which results in the formation of thin bands of iron on the ocean floor. The oxygen produced results in these iron ores.
Over the span of a billion years, enormous quantities of iron were accumulated at the ocean floor. These occurrences took place around 3.5 and 2.5 a billion years ago. The enormous reserves that were created at that time include the iron ore that is being mined in South Africa, Australia, and the United States. Once the iron was removed from the water, oxygen could begin to accumulate in the air and sophisticated life forms could begin to breathe deeply.

If a geologist found preserved mud cracks, he or she could conclude that the environment in which they formed ________.
If a geologist found preserved mud cracks, he or she could conclude that the environment in which they formed was once an area of drying or desiccation.
Mud cracks, or desiccation cracks, form in mud layers that have been exposed to drying. As the mud dries, it contracts and forms a series of cracks that can range from a few millimeters to several centimeters in size. The shapes of these cracks are usually polygonal and are typically segmented by radial cracks.
Mud cracks form when water evaporates from the surface of a mud layer, leaving behind a dry surface. This process is most common in areas with low rainfall, such as deserts, and in areas with a high rate of evaporation, such as the margins of saline lakes. The mud cracks form when the surface layer of mud dries faster than the underlying layer. As the surface layer contracts, cracks form, eventually becoming interconnected and forming a network of cracks.
The presence of mud cracks is an indication of a past environment of drying or desiccation. The size and shape of the cracks can also provide clues about the rate of evaporation and the amount of water present in the environment when the cracks formed. For example, if the mud cracks are shallow, then the evaporation rate was likely low. However, if the mud cracks are deep, then the evaporation rate was likely high.

The rotation of the earth on it's axis will impact biomes because it affects the length of day and night. Answer true or false. Your answer
False. The rotation of the earth on its axis does not affect the length of day and night.
The length of day and night are solely determined by the earth's orbit around the sun. The rotation of the earth on its axis is what causes the sun to rise in the east and set in the west, and also determines the amount of daylight a certain location receives. This, in turn, affects the types of biomes that exist in certain regions.
As the earth rotates, different parts of the earth receive more or less sunlight, which can cause different climates and environments to form. Therefore, the rotation of the earth on its axis does have an effect on biomes, but it does not directly affect the length of day and night.

What was the primary way the farms in the South differ from those in the north?
The fact that southern farmers used a plantation system to generate cash crops set them apart from their northern counterparts.
All 13 American colonies utilized slave labour throughout the colonial era (1600–1775). Slaves were employed in the shipbuilding industry, among others, throughout the North. Slaves were employed throughout the South to produce lucrative crops including indigo, rice, and tobacco.
After America gained its independence and began making its own laws, attitudes about slavery altered. While some states began to ban slavery after 1800, others continued to practice it. One of the most significant changes was that Southern states concentrated primarily on cultivating cotton, a single very significant cash crop. America became the world's biggest cotton exporter.
