How does the moon position change?
The Moon's position changes due to Gravity. The Moon revolves around earth. However, due to earth's axis we see the moon many different positions during the year, that we would not normally see. This is also responsible for eclipses. Which can only be seen on certain parts of earth, also because of the axis.
A2.
As the earth spins on it's axis, the moon appears to move across the night sky against a backdrop of stars.
The next day, the same thing happens but the moon follows a slightly different path. This is because the moon is also moving around the earth, in an orbit.
As the moon orbits the earth it presents a different angle to the sun. This causes the reflection to shine from a different edge, causing the phases of the moon.
Inevitably there will be a time when the moon gets betwen the sun and the earth and causes a shadow to pass over the earth's surface. This is an eclipse. Each time a shadow is cast, it tracks across a different part of the earth and only from this path, can a full eclipse be seen.
What is the surface temp of the star Eltanin?
The surface temperature of the star Eltanin is approximately 5450 degrees Celsius. It is classified as a K-type giant star and is located around 64 light-years away from Earth in the constellation Draco.
What would happen to your weight if the gravitational pull got three times stronger?
If the gravitational pull got three times stronger, your weight would also increase by three times. This means that you would feel heavier and it would be more difficult to move around or lift objects. Your body would experience an increase in pressure on your joints and muscles, which could lead to discomfort or fatigue.
What are some animals that live by the continental slope?
Some animals that live by the continental slope include deep-sea fish like anglerfish and lanternfish, bottom-dwelling creatures like sea cucumbers and sea stars, and pelagic species such as whales and dolphins that may traverse the slope in search of food. These animals have adapted to the unique pressures and conditions found in the deep ocean environment along the continental slope.
What forms leftover material from a supernova?
The leftover material from a supernova explosion forms either a neutron star or a black hole, depending on the mass of the collapsing core. A neutron star is extremely dense and composed mostly of neutrons, while a black hole is a region of spacetime where gravity is so strong that not even light can escape.
Do grasshoppers have six legs?
Yes, grasshoppers have six legs. Like all insects, they are characterized by having three pairs of legs. These legs are adapted for jumping, allowing grasshoppers to cover considerable distances in a single leap.
How do religoius people think the universe was formed?
"Relgious" is kind of a broad term, specify which religion you are trying to familiarize with. To give you a broad understanding of how many religious believers, believe, that the Universe was created, many believe everything was created by GOD. God is the only one that could create this complex universe, and us humans were created in his image.
Why does the moon reapeat phases every 29.5 days when even though it orbits Earth every 27.3 days?
The moon's phases repeat every 29.5 days because it takes that long for the moon to complete a full cycle of phases, from new moon to new moon. The 27.3 days is the amount of time it takes for the moon to orbit Earth, but the change in position relative to the sun causes the phases to take slightly longer.
When groundwater is heated below the surface to boiling by hot igneous rock what can form?
- hot springs
- hot mud pots
- geysers
- mineral springs
- etc.
When did people first start exploring space?
If you mean by observation, pretty much since man could draw. There are detailed "maps" of star patterns in languages too old for us to read, and there are pre-Judeo-Christian models of the night sky. Moon gods are a common religious theme - pretty much forever.
If you mean physically, NASA's space program was initiated during Kennedy's administration in response to the Soviets. Why? We wanted to be there first, and technically we were (at least, on the moon.)
What happens to the food web if an organism becomes extinct?
If an organism becomes extinct, its predators may struggle to find alternative food sources, leading to population declines or shifts in their feeding habits. This can have cascading effects on other species within the food web, potentially disrupting the balance and stability of the ecosystem.
When is day and night equally long?
Day and night are equally long during the spring and autumn equinoxes. At these times, the Sun is directly above the equator, resulting in approximately 12 hours of daylight and 12 hours of darkness worldwide.
When a planet is closer to the Sun is the orbit around the Sun shorter or longer?
When a planet is closer to the Sun, its orbit around the Sun is shorter because it has a smaller distance to travel in completing one orbit. The time it takes for a planet to go around the Sun is determined by its distance and speed.
What is safest place if wolf creek dam breaks in tn?
In the event of the Wolf Creek Dam breaking in Tennessee, the safest place would be at higher ground or further away from the potential flood zone. Following evacuation instructions from local authorities and moving to designated emergency shelters would be the best course of action to ensure safety.
Is a lunar eclispe in day or night?
A lunar eclipse can occur during the night when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. However, it is also possible to have a partial lunar eclipse during the day, depending on the position of the Moon and the Earth's shadow.
Why is the Vishnu schist visible at earths surface?
The Vishnu Schist is visible at Earth's surface because it is an exposed metamorphic rock unit that has undergone intense heat and pressure deep within the Earth's crust. Over millions of years, uplift and erosion have brought the Vishnu Schist to the surface, where it can be seen and studied by geologists.
What percent of the outdoor air is oxygen?
20%
Nitrgopen is 79%
The remaining 1% is made up of Carbon dioxide, Methane, Water vapour, Sulphur dioxide, and collectively the Noble(inert) gases.
In space there is no gravity, so the planets can't fall down! The also stay on the same plane because they are attracted to the sun.
They don't fall into the Sun because their speed is too great to let them fall straight in. The Sun's gravitational attraction only makes them curve towards the Sun as they move in their orbit. The force makes them take up elliptical orbits instead of just shooting away in a straight line.
Why does moon turn red in total lunar eclipse?
Probably the atmosphere acts as a kind of prism such that frequencies toward the 'red' end of the spectrum get bent and more focused toward the moon. Earth's gravitational field may add to this phenomenon as well by bending the red end of the spectrum inward.
Why do poles experience about six months day and six months night?
Poles experience about six months of day and six months of night due to the tilt of Earth's axis. When a pole is tilted towards the Sun, it experiences continuous daylight as the Sun remains above the horizon for an extended period. Likewise, when the pole is tilted away from the Sun, it results in continuous darkness for an extended period.
Why is jacobabad having high temperature?
Jacobabad is known for having high temperatures due to its geographical location in a hot and arid climate zone. Additionally, the lack of vegetation and water bodies in the area further contribute to the heat. Factors such as urbanization and industrial activities can also lead to increased temperatures in the region.
A primordial black hole would need to have an initial mass of about 2.2 x 10^11 kilograms in order to be just disappearing now due to Hawking radiation. This is based on the time it takes for a black hole to evaporate completely through Hawking radiation, which is about 2.1 x 10^66 years for a black hole of this mass.
When did dolphins appear on earth?
Fossil records suggest that dolphins evolved around 10-15 million years ago during the Miocene epoch. They are believed to have evolved from land-dwelling mammals that returned to the sea.
Which object orbits earth in both the earth centered and sun centered models?
That would be the moon. We've never thought of it that way ... the only object
whose status didn't change between the geocentric and heliocentric model.
Thanks for showing it to us.
