Science
The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.
203,801 Questions
What is the average temperature of Phobos?
Temperature � 233 K is known as Phobos temperature.
The temperatures of Phobos, one of the moons of Mars,range from about −4 °C (25 °F) to −112 °C (−170 °F), on the sunlit and shadowed sides respectively.
What are two evidence of solar convection?
Two pieces of evidence for solar convection are the presence of granules on the solar surface, which are small convection cells visible in the photosphere, and solar oscillations caused by the motion of convection currents beneath the surface, which can be measured through helioseismology.
Are shadows involved in every eclipse?
Yes, shadows are involved in every eclipse. A solar eclipse happens when the Moon's shadow falls on Earth, blocking the Sun's light. A lunar eclipse occurs when Earth's shadow falls on the Moon, darkening it.
Is Pluto the same size as a astoried?
Pluto is actually a large asteroid that has been captured in the sun's gravitational pull.
What are the 3 main gasses in the atmosphere and what percentage is each?
Nitrogen ~ 78%
Oxygen ~ 21%
CO2(and other gasses) ~ 1%
What do you call an explanation about something that happens in nature?
An explanation about something that happens in nature is called a natural phenomenon. This term is used to describe events or occurrences that are a result of natural processes or interactions within the environment.
Isopods have compound eyes that are capable of detecting light and movement, but their vision is generally considered to be poor. They rely more on their sense of touch and chemical receptors to navigate their environment.
In terms of numbers which is the most abundant organism in the food web?
The top predator, because it consumes other species with relatively low population densities. As trophic level increases, less energy flows to what are often larger organisms. Thus, the maximum sustainable population size decreases.
Why is it cold though the sun is out?
The earth has 4 seasons and each season the angle to the sun changes.
As example, when its winter in North America, North America is tilted upwards and the sun is hitting more of the southern hemisphere. The sun is still out but is cold even with the sun.
What type of cloud does rising air form?
Rising air typically forms cumulus clouds, which are fluffy and white with a flat base and a puffy top. These clouds are associated with fair weather conditions but can develop into larger storm clouds if conditions become unstable.
What type of reflection shows a clear image?
A specular reflection shows a clear image. This type of reflection occurs when light bounces off a smooth and shiny surface, like a mirror, resulting in a well-defined and clear image being formed.

One example of a habitat beginning with "q" is a quarry. Quarries are areas where stone, minerals, or other resources are extracted from the earth. They can support unique ecosystems depending on the type of material being mined and the surrounding environment.
How can you measure irregular objects?
do you mean getting the area???
For Area:
Place the irregular objects on a graph paper and trace the outline of the object. Now count the complete square as 1 and other incomplete as 0.5 or so according to how much it occupies. Now finally sum them up and that would be the area of that particular object.
If you mean to say volume then:
You can find the volume of an irregular object by the displacement of water. In order to find the volume by displacement you need a measuring cylinder.
In the measuring cylinder pour some water in it up to a certain point such that you can read it. Now insert the irregular object in to the cylinder gently. Now read the height of water on the cylinder. Now deduct the first reading from second, that should be your volume of irregular object.
If finding perimeter then
trace out the outline of the object and simply measure the length of the object on the paper.
** Note: you must trace all side that you can see
well that is a very open question, because there are lots of meanings, but as a faerie and merfolk studier and researcher i will try my hardest to answer that.
mermen as we humans call them, can live with alot less oxygen, so, like fish, they can breathe in the oxygen from the water. mermen are just like humans, exept they have evolved to live in water.
you may notice that in many ancient tales and legends, they have fish tails or features, which they do. Fins and scales are common on merfolk, but they do vary because like humans, who have differents coloured skin and heights, mermen adapt to their surroundings.
for merfolk, reproducing is an everyday part of life and they do not take shame or restrain from it.there are many tales of mermen luring humans into the water and impregnating them. however, these are quite false, but they do delight with humans but they would never force them to. mermen reproduce the same way humans do as they have always have either a penis or vagina in the groin area, even if they have a tail.
They often survive in clans in shallow seawater in places close to the equator. i will not reveal the places in which the clans are as i have made a covenant to not reveal the whereabouts of their clans.
they eat a diet of fish and seaweed normally, although they have been known to attack and consume humans if the human is threatening.
the merfolk way of life is under threat because of pollution and overfishing and the Indonesian clan has already faded away.
That is all the basic information on mermen.
How does the warming of the worlds oceans flow of the water cycle?
The warming of the world's oceans can intensify the water cycle by increasing evaporation rates, leading to more water vapor in the atmosphere. This can result in more frequent and severe weather events like storms and heavy rainfall. Additionally, warmer ocean temperatures can impact ocean currents, which play a significant role in distributing heat around the globe.
What controls the way an ball moves in space?
The motion of a ball in space is primarily influenced by external forces acting upon it, such as gravitational pull from nearby celestial bodies or thruster propulsion. Additionally, the initial velocity and angle at which the ball is launched will determine its trajectory. Once in motion, the ball's path can be further affected by other factors like air resistance or collisions with other objects.
It would be December in the Philippines if the shadow of a vertical flagpole is pointing southward at noon time. This is because in December, during the winter solstice, the sun is at its lowest point in the sky, causing shadows to be cast towards the south at noon.
Why is Orion not visible in summer?
During the summer, Orion is not visible in the night sky because it is located on the other side of the Earth, behind the sun. Orion is a winter constellation that is best viewed from late autumn to early spring.
Yes, NASA is an American agency, part of the United States government. While it collaborates with international partners on various space missions and projects, the agency itself is not an international organization.
Definition of the word centrum in the world of colors?
In the world of colors, centrum refers to the central point or focal point of a color palette. It is the main color or colors that anchor and define the overall scheme, often guiding the selection of complementary colors.
Does tourmaline glow in black light?
Yes, certain varieties of tourmaline may exhibit fluorescence when exposed to UV/black light due to trace elements within the crystal structure. The fluorescence can range from a variety of colors including blue, green, and pink.
What is the material cause of man?
The material cause of man is the physical matter that makes up the human body, including elements such as carbon, hydrogen, oxygen, and nitrogen. This material forms the building blocks of tissues, organs, and systems that comprise the human body.
How were the monastry organised?
Monasteries were typically organized around a clear hierarchy, with an abbot at the top overseeing the monks or nuns. Each monastery had specific rules or guidelines for daily life and worship, such as the Rule of Saint Benedict for Benedictine monasteries. Monks and nuns would participate in communal prayer, work, and study as part of their daily routine.
How can a prism break up sunlight into different colours?
A prism can break up sunlight into different colors through the process of dispersion. When sunlight enters a prism, it is refracted at different angles depending on the wavelength of each color in the visible spectrum. This separation of colors creates a rainbow effect, with each color appearing at a different position as it exits the prism.
