Answer:
B. Phytoplankton
Explanation:
In the antarctic, the basic source of food is the phytoplanktons which are autotrophic and self-feeding organisms of the plankton community and these play a key role in the ocean, the sea, and the freshwater and they comprise of the tiny individual member and have a global biomass of 1%. They are rich with vitamin B, and they at times can mead to the acidification of the oceans when increase in numbers thus needs to be taken care of hence they are eaten by the shrimp population and they then contribute to the increase n the population of the bigger fish i.e the whales and thus forms the basic source of the food web. These phytoplanktons are also known as the producer if the antarctic food chain.Who are "uncontacted peoples"? Who are "uncontacted peoples"?

Which of the following is the best explanation of the fact that ag. production of floodplains is often relatively high?a. on flood plains soils tend to be nutrient-rich and fertileb. on floodplains high water tables make irrigation rich and fertilec. periodic flooding leaches toxic pollutants into floodplain soild. periodic flooding prevents the PH of floodplain soils from becoming too high
Answer:
a. on flood plains soils tend to be nutrient-rich and fertile
Explanation:
A floodplain is an area of the land that is adjacent to the river or steam and that stretches the channels of the base to the enclosing valleys and the soi, usually, consist of clays and silt and sands and thus the meandering water erodes the downstream of the deposition of the silt behind the lands. It also represents the and by the fluvial terraces and in terms f the ecology they are diverse and most fertile lands ad thence the wetlands and the riparian zone are those of the soil as an intermediate supply of nutrient and thus are valuable for the agriculture.Please answer using 350 words or less.
List and describe one process for each of the following sources that could be eroding the beach.
1. onshore, naturally occurring on land or around the shoreline
2. offshore, naturally occurring out at sea, away from the shoreline
3. anthropogenic, influenced or altered by people
Answer:
All these impact the coastal lands
Explanation:
The formation of the beach generally being by the erosion of the continental materials like the sand, cobbles and the gravel and that is washed towards the shores. And these get deposited at the shores by a longshore current and thus s described as the process of the coastal erosion. By erosion of the agent like the tods, waves and the wind-driven current. The offshore erosion process is a result of the actions the water currents and is temporal erosion process and is caused by the cycle of the sedimentation and associated with the removal of these particles by the backwashing waves. Thereby cutting off the sand that was deposited and increase in the depth of the shorelines. There are various associated causes of sand removal by man-made or anthropogenic impacts like the example of climate change taking place. Loss of sands due to the mining process and building of ports.

The highest recorded temperature on Earth was in a ______________________
a. low-latitude, high elevation desert in Mexico.
b. tropical rain forest in Brazil.
c. high-latitude, high-elevation desert in Mongolia.
d. low-latitude, low-elevation desert in Libya
Answer:
d. low-latitude, low-elevation desert in Libya
Explanation:
From 1922 until 2012, the WMO record for the highest official temperature on Earth was 57.8 °C (136.0 °F), registered on September 13, 1922 in 'Aziziya, Libya.
The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes have high temperatures due to direct sunlight, contributing to high temperatures especially in deserts like those in North Africa.
The highest recorded temperature on Earth was in a low-latitude, low-elevation desert in Libya. Low latitudes, which are near the equator, generally have high temperatures because the sun's rays hit these areas more directly. This solar intensity, coupled with the low elevation that typically traps more heat due to denser atmosphere at lower altitudes, leads to high temperatures, particularly in desert regions.
Deserts are defined by their low precipitation and because of the sparse cloud cover, there is more solar energy absorption during the day, leading to extreme temperatures. The subtropical deserts, such as those in North Africa including the Grand Erg Desert, can experience very high temperatures. At low elevations in these deserts, the lack of moisture and minimal cloud cover contribute to the recording of some of the highest temperatures on Earth.

A geostationary satellite is one that stays over one location on the Earth’s surface at all times.
(A) All must have the same approximate mass.
(B) All must center their orbit with the center of the Earth.
(C) All must must travel over the equator.
(D) All must have the same distance from the Earth
(E) All must have the same period.
(F) All must have the same speed.
A geostationary satellite is one with an orbital period of 24 hours, remaining over the same Earth location. To maintain this, it must orbit in the equatorial plane and at a specific radius where gravitational forces allow for a period equal to Earth's rotation.
Explanation:The question you've asked pertains to the characteristics of geostationary satellites. These satellites are unique because they have an orbital period that matches the Earth's rotational period, hence remaining above the same point on the Earth's surface at all times which means all must have the same distance from Earth. They must satisfy specific criteria to maintain a geostationary orbit:
They must orbit in the equatorial plane, which allows them to stay in line with a fixed point on Earth.
The radius of the orbit is determined by the gravitational force and the need for the orbital period to be exactly 24 hours. The distance from Earth will vary depending on these factors, but it is consistent for all geostationary satellites.
The orbital period, or the time it takes to complete one orbit, must be equal to one Earth day, which is approximately 24 hours.
Although not inherently necessary for geostationary orbits, the satellite's speed and mass may be consistent due to the uniform orbital requirements, but these are not defining characteristics of geostationary satellites.
With these conditions met, geostationary satellites are invaluable for various applications, such as communications, weather monitoring, and broadcasting.
Desert climate associated with a rain-shadow is found ________.
a. on the windward side of mountain ranges
b. on the leeward side of mountain ranges
c. in the middle of flat plains
d. along continental coastlines
Answer:
B. On the leeward (inward) side of coastal mountain ranges
Explanation:
In contrast to the windward side of a mountain which is moist, the leeward side typically has a dry, warm climate. This is because by the time air rises up the windward side and reaches the summit, it has already stripped of the majority of its moisture.
Answer:
The answer is b): on the leeward side of mountain ranges.
Explanation:
Desert climate associated with a rain-shadow is found on the leeward side of mountain ranges. A rain shadow usually forms as a dry area of land on the side of a mountain that is protected from prevailing windflow, and associated with certain types of weather systems. The side of a mountain that is protected from prevailing windflow is known as the down-wind side or the leeward side.
