The plains have little flora. A desert is defined by minimal rainfall, sparse flora, and extreme temperatures. These climatic circumstances are not conducive to plant development. This is why plains have so little flora. (ii) Sahara arid dwellers dress in thick garments. The deserts have sparse greenery due to unfavourable climatic circumstances for the flora world to thrive. The desert has either an extreme hot or extreme frigid temperature and gets little rainfall, making it unsuitable for vegetation growth. The Sahara arid people dress in thick garments. The temperature in the deserts is either very hot and arid or very frigid and dry, making it impossible for vegetation to develop. Rainfall is scarce. HenceAs a result, vegetation cannot develop in dry circumstances. For the most part of the year, the soil is either sandy (in hot deserts) or blanketed in snow (in frigid deserts). The flora of an area is typically determined by two factors: temperature and soil. The desert's climatic conditions are either extremely hot and arid or extremely frigid and dry, making it unfit for plant development in this area.

it is a warm summer day, and you are shopping in downtown chicago, just a few blocks from lake michigan. all morning the winds have been calm, suggesting that no major weather systems are nearby. by midafternoon, should you expect a cool breeze from lake michigan or a warm breeze originating from the rural areas outside the city?
On a warm summer day in downtown Chicago, just a few blocks from Lake Michigan, if the winds have been calm all morning and no major weather systems are nearby, you should expect a cool breeze from Lake Michigan in the mid-afternoon.
This is because of a phenomenon known as the lake breeze effect, where the temperature difference between the warmer land and the cooler water causes a circulation of air from the lake toward the land during the day. The lake breeze can bring in cooler, more humid air from the lake, which can provide relief from the heat and humidity in the city. This effect is particularly noticeable on calm days when there are no strong winds to disrupt circulation.
In contrast, a warm breeze originating from the rural areas outside the city is less likely, as it would require a significant weather system or wind pattern to bring warm air into the city. Without any such weather systems or wind patterns nearby, the lake breeze effect is the more likely scenario.

What was Percy Julian most significant achievement
Answer:
Percy Julian's most significant achievement was his work on the synthesis of cortisone and other medicinal compounds from plant sterols. At the time, cortisone was a newly discovered drug that had significant potential to treat a variety of diseases, including arthritis and other inflammatory conditions. However, the only source of cortisone was from the adrenal glands of animals, which made the drug expensive and difficult to produce in large quantities.
Julian's work involved developing a method to synthesize cortisone from soybeans, a process that had never been achieved before. This was a major breakthrough that not only made cortisone more widely available but also paved the way for the synthesis of other important medicinal compounds. Julian's work on steroid synthesis also had important implications for the development of the birth control pill and other hormone-based therapies.

T/F. Highly fluid basaltic lava may cool with a smooth, ropy surface called pahoehoe, whereas lower temperature, slower flowing, more viscous basaltic lava commonly has a rough, blocky texture called.
Answer:
True
Explanation:
Highly fluid basaltic lava, with low viscosity and high temperature, may cool with a smooth, ropy surface called pahoehoe, whereas lower temperature, slower flowing, more viscous basaltic lava commonly has a rough, blocky texture called a'a. These different textures result from the different ways the lava flows and cools, with pahoehoe lava forming when the surface of the lava solidifies and wrinkles as it is pushed forward by the still-liquid lava underneath, and a'a lava forming when the lava is too viscous to flow easily, leading to the formation of rough, jagged blocks as the surface cools and solidifies. These terms are commonly used to describe the textures of basaltic lava flows in volcanic regions around the world.
The statement "Highly fluid basaltic lava may cool with a smooth, ropy surface called pahoehoe, whereas lower temperature, slower flowing, more viscous basaltic lava commonly has a rough, blocky texture called aa. " is True as Basaltic lava is a type of volcanic rock that is extremely fluid and contains a lot of iron and magnesium.
These types of volcanic rocks are the most frequent on Earth and make up the majority of the ocean floor's crust. Basaltic lava is usually dark-colored, ranging from grey to black, and has a smooth texture. Basaltic magma is not very sticky, so it is free to flow far from the eruption site.
When lava flows swiftly and cools rapidly, it usually creates a rough, jagged texture known as aa (pronounced "ah-ah"). Aa has a texture similar to clinkers; the lava forms are twisted, sharp-edged fragments of lava, resembling a jumbled heap of angular blocks and rubble.
Pahoehoe, When basaltic lava flows gradually and cools slowly, it usually develops a smooth, ropy texture called pahoehoe (pronounced "pah-hoy-hoy"). Pahoehoe, also known as "ropey" lava, appears like coiled ropes, wrinkled or folded ribbons, and smooth, billowy sheets.
Basaltic lava is the most frequent kind of lava on the planet, and it is generated by many volcanoes. Basaltic lava is defined by its low viscosity, meaning it flows quickly and has a smooth texture, making it ideal for creating shield volcanoes with shallow slopes.
Furthermore, because of its fluidity, basaltic lava is the least dangerous kind of lava and poses little danger to people living nearby. Highly fluid basaltic lava may cool with a smooth, ropy surface called pahoehoe, whereas lower temperature, slower flowing, more viscous basaltic lava commonly has a rough, blocky texture called aa.

in eastern north america, large earthquakes blank . multiple select question. are the product of recent subduction along the east coast have unusually high strain rates mostly occur at the sites of failed rifts are associated with low-strain regions lack significant recent faulting
Answer: Lack significant recent faulting
Explanation:
In eastern North America, large earthquakes mostly occur at the sites of failed rifts and lack significant recent faulting.
Eastern North America is not located near any active plate boundaries, so it does not experience the large earthquakes that are typically associated with subduction zones or transform faults. However, there are still some earthquakes that occur in this region.
One of the main causes of these earthquakes is failed rifts. These are areas where the continental crust attempted to split apart in the past, but the process was not completed. As a result, there are zones of weakness in the crust that can be reactivated and produce earthquakes.
Additionally, eastern North America generally lacks significant recent faulting. This means that there are not many active faults in the region that are capable of producing large earthquakes.
Overall, while earthquakes do occur in eastern North America, they are generally smaller and less frequent than those that occur in more seismically active regions.

Given a parcel of air at 40°C and absolute humidity of 35 g/m3, if saturated, what would absolute humidity be?
Explanation:
To determine the absolute humidity of a parcel of air when it is saturated, we need to calculate its maximum water vapor capacity at 40°C, also known as its saturation specific humidity.
The maximum water vapor capacity of air increases with temperature, so we need to use a formula that takes into account both temperature and pressure. One such formula is the Magnus-Tetens equation:
e = 6.112 × exp[(17.67 × T)/(T + 243.5)]
where e is the vapor pressure in hPa and T is the temperature in degrees Celsius.
Using this equation, we can calculate that at 40°C, the vapor pressure of saturated air is:
e = 6.112 × exp[(17.67 × 40)/(40 + 243.5)] = 7.958 kPa
Next, we need to convert this vapor pressure into absolute humidity using the following formula:
AH = (0.622 × e)/(P - 0.378 × e)
where AH is the absolute humidity in g/m3, P is the atmospheric pressure in kPa, and 0.622 and 0.378 are constants representing the molar mass ratio of water vapor to dry air and the ratio of the gas constants for water vapor and dry air, respectively.
Assuming a standard atmospheric pressure of 101.325 kPa, we can calculate that at 40°C and saturation, the absolute humidity of air would be:
AH = (0.622 × 7.958)/(101.325 - 0.378 × 7.958) = 51 g/m3
Therefore, if the initial parcel of air had an absolute humidity of 35 g/m3 and was heated to its saturation point at 40°C, its absolute humidity would increase to approximately 51 g/m3.
