it is 2 p.m. on the spring equinox. what is the local sidereal time?
Answers
Assuming that the observer is located at a longitude of 120 degrees west and that it is currently 2 p.m. local time on the spring equinox, the local sidereal time would be approximately 20:00 (8 p.m.).
To determine the original sidereal time( LST) at a given position and time, we need to know the longitude of the bystander's position and the current sidereal time( ST) at the high peak, which is the imaginary line that runs through the Royal Observatory in Greenwich, England. On the spring equinox, which occurs around March 20 21 each time, the ST at the high peak is equal to 0 hours( or 0 degrees), because the vernal equinox marks the point at which the Sun crosses the elysian ambit from south to north.
At this moment, the right ascent of the Sun is exactly 0 hours. To calculate the LST, we need to know the difference between the bystander's longitude and the high peak, expressed in hours of time. For illustration, if the bystander is located at a longitude of 120 degrees west of Greenwich, the time difference would be 8 hours(120/15 = 8).

what landforms would still form, even if the planet is without a hot molten interior, without an atmosphere, and without liquid
Answers
"what landforms would still form, even if the planet is without a hot molten interior, without an atmosphere, and without liquid" is the Tectonic plates, mountain ranges, and valleys will still form, even if the planet is without a hot molten interior, without an atmosphere, and without liquid.
Landforms refer to the natural geographical features of the earth's surface, such as mountains, hills, valleys, and plains. Some of the landforms that will still form even if the planet is without a hot molten interior, without an atmosphere, and without liquid include:
Tectonic platesMountain rangesValleysThe reason these landforms would still form is that they are formed by the movement of tectonic plates. The movement of the plates causes the formation of mountains and valleys. When two plates move apart, they create a rift valley.
When two plates move together, they form mountain ranges. A tectonic plate refers to a section of the crust that moves around on top of the mantle. Tectonic plates form as a result of the Earth's internal heat. As the mantle moves, the plates move as well.
When two plates collide, they can create mountains, volcanoes, and earthquakes. When two plates separate, they can form valleys and rifts.

Far-north ground stations give excellent communications coverage for polar-orbiting satellites, but they also have the benefit of low peak rainfall similar to the southwest continental United States. Consider a ground station being constructed on the southern coast of Greenland. Using the information, tables, figures, and equations in the charts and the book, find the specific attenuation γ
R
for an 8GHz signal and a 20GHz signal, assuming both are vertically polarized. Why is the 20GHz signal attenuated more (i.e., explain the conceptual physical meaning of the changes in constants k and α) ?
Answers
The higher frequency 20GHz signal experiences greater attenuation compared to the 8GHz signal due to the effects of increased atmospheric absorption and rain attenuation at that frequency.
To find the specific attenuation γR for an 8GHz signal and a 20GHz signal, we need to consider the information provided in the charts and equations specific to the southern coast of Greenland. However, I can explain the conceptual physical meaning behind the changes in constants k and α that result in greater attenuation of the 20GHz signal compared to the 8GHz signal.
In general, as the frequency of an electromagnetic signal increases, the attenuation or weakening of the signal as it propagates through a medium also increases. This is due to various factors such as absorption, scattering, and atmospheric effects.
The constant k in the attenuation equation represents the specific attenuation due to atmospheric gases. At higher frequencies, the interaction between the electromagnetic waves and atmospheric molecules becomes more significant, leading to increased absorption and attenuation of the signal. Therefore, the value of k increases with frequency.
Hence, the higher frequency 20GHz signal experiences greater attenuation compared to the 8GHz signal due to the combined effects of increased atmospheric absorption (represented by higher k) and increased rain attenuation (represented by higher α) at that frequency.

how are weather and climate related? how are weather and climate related? climate is the weather at a particular place and time. climate and weather are both produced by plate tectonics. weather is climate that can be measured.
Answers
Answer:
Explanation:
how are weather and climate related? how are weather and climate related? climate is the weather at a particular place and time. climate and weather are both produced by plate tectonics. weather is climate that can be measured.
Weather and climate are closely related, as they both describe the atmospheric conditions of a particular place. However, the main difference between the two is the time scale: weather refers to short-term changes in the atmosphere, while climate represents the long-term average of weather patterns.
Weather includes daily phenomena such as temperature, humidity, precipitation, and wind. It can change from day to day, or even within a single day. Weather is influenced by various factors, such as solar radiation, air pressure, and atmospheric circulation.
Climate, on the other hand, is a long-term average of weather conditions over a period of at least 30 years. It describes the typical patterns of temperature, precipitation, humidity, and wind in a specific region. Climate is influenced by factors such as latitude, altitude, and proximity to bodies of water.
Although tectonics plate do not directly produce weather and climate, they can affect climate by influencing the distribution of land and ocean, which in turn influences ocean currents and atmospheric circulation patterns.
In summary, weather and climate are related because they both describe the atmospheric conditions in a certain place. Weather refers to short-term changes, while climate is the long-term average of weather patterns. They are influenced by various factors, including solar radiation, air pressure, and the Earth's position relative to the Sun. Although plate tectonics do not directly produce weather and climate, they can impact climate by affecting the distribution of land and ocean.

which of the following contribute to the growth of composite volcanoes?
multiple select question.
a. ash column eruptions
b. eruption of lava flows
c. pyroclastic flows
d. caldera collapse
Answers
The growth of composite volcanoes is contributed to by the eruption of lava flows and pyroclastic flows.
Composite volcanoes, also known as stratovolcanoes, are formed by the alternating eruption of lava flows and pyroclastic flows. Lava flows are a significant factor in the growth of composite volcanoes. As the volcano erupts, molten lava is ejected from the vent and flows down the sides of the volcano, gradually adding layers of solidified lava to its structure. Over time, these repeated eruptions and lava flow events contribute to the growth and height of the composite volcano.
Pyroclastic flows, on the other hand, also play a role in the growth of composite volcanoes. These flows are a mixture of hot gases, ash, and volcanic debris that rush down the sides of the volcano at high speeds. As pyroclastic flows move downslope, they deposit layers of volcanic ash and other materials, adding to the overall size and volume of the volcano.
It's important to note that ash column eruptions and caldera collapse, which are mentioned in the options, do not directly contribute to the growth of composite volcanoes. Ash column eruptions occur when volcanic explosions produce tall columns of ash and gas that are released into the atmosphere. Caldera collapse, on the other hand, is a result of the collapse of the volcano's summit area following a massive eruption. While these events may occur in the life cycle of a composite volcano, they do not directly contribute to its growth.

"If the amount of ice on Earth's surface were to suddenly double, as a result of albedo global temepratures would:... increase decrease remain the same Depends on CO2 because CO2 controls albedo
Answers
If the amount of ice on Earth's surface were to suddenly double, as a result of albedo, global temperatures would decrease.
Ice has a high albedo, meaning it reflects a significant amount of sunlight back into space. When the amount of ice on Earth's surface increases, such as through the expansion of glaciers or ice sheets, the overall albedo of the planet increases. This leads to more incoming solar radiation being reflected back into space rather than being absorbed by the Earth's surface. As a result, less solar energy is available to warm the planet, leading to a decrease in global temperatures.
It is important to note that this statement assumes other factors remain constant and does not take into account the complex interactions of various feedback mechanisms in the climate system. In reality, the Earth's climate is influenced by multiple factors, including greenhouse gas concentrations, atmospheric circulation patterns, and oceanic currents. These factors can interact in complex ways and can either amplify or dampen the initial temperature change caused by albedo.
In summary, if the amount of ice on Earth's surface were to double, the increased albedo would lead to a decrease in global temperatures. However, it is crucial to consider that climate is influenced by various factors, including greenhouse gases, and the actual temperature response would be influenced by these additional factors.
