The Moon's orbit around the Earth makes different amounts of the Moon's illuminated side visible to Earth. About two hours after sunrise, I notice the moonset on my way to work is the cause of the lunar phases.
As the Moon orbits our planet, its changing position means that the Sun illuminates different regions, creating the illusion that the Moon is changing shape over time. The best way to understand the phases of the moon is to go outside on a clear night when the moon is in the sky and watch it regularly.
The moon itself does not emit light. It is lit by the sun. As the Moon orbits the Earth, the illuminated portion of the Moon that we see changes, creating lunar phases.

A climate zone categorized as a desert will have an annual rainfall of less than?
A climate zone categorized as a desert will have an annual rainfall of less than 25 cm.
What is the desert's temperature and rainfall like?Many average annual temperatures range between 20 and 25 degrees Celsius. The extreme maximum temperature ranges from 43.5 to 49 degrees Celsius.
Minimum temperatures have occasionally dropped to -18 degrees Celsius. Most experts agree that a desert is defined as an area of land that receives less than 25 centimeters (10 inches) of precipitation per year. In a desert, evaporation frequently far exceeds annual rainfall.
Rainfall in the Desert
Some deserts, such as the world's driest, the Atacama, receive little or no rain. These areas are extremely arid, with very little life. Other deserts, such as Arizona's Sonoran Desert, receive close to the maximum yearly rainfall for deserts and are fairly well populated with a diverse range of fauna and flora.
While still arid, the Sonoran Desert is lush in comparison to other deserts, supporting over 2,000 plant species.
Rains in the spring produce incredible displays of greenery and flowers as dormant plants take advantage of the rain.
Saguaro cacti grow to enormous proportions, collecting and storing massive amounts of water when it rains and surviving for months until the next rain.

a. plate tectonics.
b. the earth system.
c. external processes.
d. the scientific method.
The correct answer is Option B) the Earth systems.
Geologists call the interconnected web of interacting processes and materials on (and in) the earth, the Earth systems.
What are the earth systems and how do they interact with each other?When the five major systems of Earth, that are, geosphere, biosphere, cryosphere, hydrosphere and atmosphere interact with each other so as to produce the environment we are familiar and comfortable with, it is called Earth systems.
Geosphere: The types of minerals present in soils, which are the end products of geologic processes, influence the vegetation and ecosystems that grow on the soil's surface. Carbon, a component of biological matter that is necessary for life, is carried to the ocean by wind and water erosion, where it finally becomes a part of the ocean floor. Ocean deposits are transported into the interior of the planet via tectonic activity. Volcanic activity has the ability to release carbon dioxide into the Earth's atmosphere over geologic timescales. One of the important cycles that connects the geosphere, atmosphere, hydrosphere, and biosphere is the carbon cycle.
Biosphere: Interactions between the biosphere and atmosphere are ongoing. All living creatures are dependent on atmospheric gases for survival. Animals and other organisms absorb oxygen from the air to utilize in all of their bodily cells, and they expel carbon dioxide back into the atmosphere.
Cryosphere: The cryosphere acts as a highly reflecting blanket to keep Earth from overheating. Compared to open water or bare ground, snow and ice reflect more sunlight. The energy balance of the entire globe is impacted by the presence or absence of snow and ice, which influences heating and cooling over the surface of the Earth.
Hydrosphere: Rain originates from clouds in the atmosphere and descends to the lithosphere as streams and rivers, providing water for both plant development and drinking for humans and animals .
Atmosphere: The three main atmospheric components that absorb radiation are ozone, carbon dioxide, and water vapor. The sun's UV energy, which is detrimental to the majority of living organisms, is absorbed by ozone. Without this protective layer in the atmosphere our skin would burn when exposed to sunlight.

Where a mid-ocean ridge is offset, the linear feature connecting and between the crests of the ridge segments is called a __________.
Where a mid-ocean ridge is offset, the linear feature connecting and between the crests of the ridge segments is called a transform fault.
Transform fault, in geology and oceanography, are type of fault in which two tectonic plates slide over each other. Transform faults can occur in parts of fault zones that lie between different offset propagating centers, or in parts that connect propagating centers to deep-ocean trenches in subduction zones.
The spatial direction of the translation error is usually parallel to the plate motion. Deformation faults are the only segments of seismically active shatter zones. Morgan's theory made a very dramatic prediction, that the direction of translation error movement is opposite to the displacement of the ocean ridge.

a. true
b. false
The answer is false.
The statement that our supply of fossil fuels, such as petroleum and natural gas, is effectively unlimited as technology develops to extract more of it, is false.
Why is the aforementioned statement false?Fossil fuels or the energy resources extracted from fossils such as oil, coal and natural gas, are non - renewable resources. These resources were formed when prehistoric plants and animals died and as time passed, gradually they were buried by layers of rock and soil.
These are available in limited amounts and even if technology is developed to extract more of it, one day the Earth's reserves of the fossil fuels will come to an end. These reserves are already being exploited by human activities and cannot be replenished fast enough to fill the increasing gap.

Choanocytes is the cell type that is responsible for water current for the sponge.
Sponges are unusual animals in that they lack definite organs to carry out their various functions. The most important structure is the system of canals and chambers, called a water-current system, through which water circulates to bring food and oxygen to the sponge. The water-current system also helps disperse gametes and larvae and remove wastes.The essential elements of the water-current system include the pores, or ostia, through which water enters the sponge (incurrent system).the choanocytes, or collar cells, which are flagellated cells that generate water currents and capture food; and the oscula, openings through which water is expelled (excurrent system).To know more about collar cells click here

How did the development of an interstate highway system change the urban landscape in the united states?.
The US interstate highway system destroyed the city's white urban middle class and lower middle-class residential areas.
New "whites only" residential areas were created in low-cost land areas outside urban and suburban employment centers and in formally rural agricultural areas by providing means of economic communication at low (relatively) cost. Those areas are being acquired by land speculators, who have profitably developed them into suburban residential housing subdivisions. With all interregional connectivity and newly built shopping and commercial centers. Before the US interstate highway, even small- to medium-sized cities had dense urban cores, with much of the development geared toward pedestrians and mass transit users. After the interstate, by the 1970s, only a few areas had the density to support pedestrian and mass transit infrastructure until more and more people depended on cars. It's popular now to blame urban areas on freeways. It's just as important to consider that many suburban areas, especially in the Northeast, need new housing developments with 2-5 acre land requirements. Also, many areas across the country have strict zoning requirements that only mandate residential development for miles and miles of land, so no one would walk that far even if they wanted to.
