Earth Sciences

Nebulae can be observed from Earth using telescopes. Their gas and dust particles reflect and emit light, making them visible to astronomers. Different types of telescopes, such as optical, radio, and infrared telescopes, can be used to study various aspects of nebulae.

The moon has no atmosphere, so there is nothing there to burn up the dust and dirt and ice and rocks, turning them into meteors, as happens on Earth. Meteors seen on Earth are so brief and fast and enclosed by the atmosphere, and so far from the Moon that you would not see Earth's meteors from the Moon.

If this is from Florida Focus, and in general terms, Modern astronomers would suggest the Sun is not the exact center of the Solar System, but would agree that the Sun is not revolving around Earth.

(the whole Earth-and-Moon "thing" = mass entity system still rotates together around the sun, so there should be enough gravity to make a tidal lock component towards the sun plausible -- if the tidal lock explanation is true, at all -- and to cause a significant deviation from a "full synchronisation" towards Earth, therefore)

do you have an answer?

There is a tidal lock component coming from the gravitational attraction between the Earth and Sun, but it is much less than that of the Earth and Moon. The tidal generating force has an equation of:

mass/distance^3 - mass divided by distance cubed.

The mass of the sun is about 27 million times larger than the moon, and it is 390 times further away than the moon. Therefore, 27 million over 390 cubed gives you 0.46. This means that the suns tide generating force is less than half that of the moon. When the sun has an effect upon the tides in certain areas of the earth, the area will have a semi-diurnal mixed tide.

A solar eclipse occurs when the moon passes between the sun and Earth, blocking the sunlight and casting a shadow on Earth's surface. There are different types of solar eclipses, including total, partial, and annular eclipses, depending on the alignment of the sun, moon, and Earth.

At what speed ? At what distance ? Between what masses ?

The question is lacking in specifications.

But it doesn't really matter, because gravity is a real force,

but centrifugal force is not a real force. So you would have to

say that gravity is stronger.

The moon will have comepleted about four rotations around the Earth.

Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is describing.

No a rainbow has to do with light. It is a refraction of light waves through a prism (in this case a rain droplet). White particles go in one side and rainbow particles come out the other side. Then they spread and you see a rainbow in the sky after it rains. Your welcome! :)

Visible light has the maximum intensity in the solar electromagnetic spectrum. The Sun emits a range of wavelengths, with visible light falling in the middle of this range. Our eyes are most sensitive to these wavelengths, which is why we perceive sunlight as bright.

The sun is lowest in the sky during the winter solstice, which usually occurs around December 21st in the Northern Hemisphere and around June 21st in the Southern Hemisphere. At this time, the sun is at its most southern or northern point, resulting in the shortest day of the year.

Comets are icy bodies that originate in the outer regions of the solar system and develop tails when they approach the sun, whereas asteroids are rocky and metallic bodies that orbit the sun mainly in the asteroid belt between Mars and Jupiter. Comets are composed of ice, dust, and rocky material, while asteroids are primarily made of rock and metal. Both comets and asteroids can pose a potential threat to Earth if they collide with our planet.

Fossils that are widespread geographically are commonly referred to as cosmopolitan fossils. These fossils are found in multiple locations around the world, indicating a broad distribution during the time period in which they were alive.

The metre (meter in the USA) is the base unit of length in the metric system. It is equal to the distance light travels in a vacuum in a time interval of 1/299792458 of a second.

Iron and nickel are solid in the inner core due to the extremely high pressure and temperature conditions present there. The pressure is so intense that it keeps the iron and nickel in a solid state despite their high melting points.

Different igneous rocks have different silica contents. I could go into loads of detail about mineralogy but what you probably need to know is that magma (as rock is immeasurably viscous as it is solid) containing high Si is more viscous that that with low Si (Silicon being Si). Basalt has low Si, andesite has high Si. Both are extrusive igneous, but form at different plate boundary types.

Birds have numerous predators in the wild, including larger birds of prey such as eagles, hawks, and owls. Mammals like cats, snakes, and foxes also prey on birds, as do some larger insects and spiders. Additionally, humans pose a threat to birds through habitat destruction, pollution, and hunting.

"Shooting stars" is a slang term for meteors and meteorites. They seem to shoot across the sky because when they fall into our atmosphere from outer space, they get so hot that they burn up. A meteorite is a meteor that makes it all the way down and lands on Earth.

it the earth is 365 days while the sun is 932,000,000 miles long to rotate sun takes up 1 earth day = 1 year for sun

The Big Dipper is a prominent star formation that resembles a ladle or dipper, with a long handle and a bowl of stars at the end. The Little Dipper is smaller and less well-defined than the Big Dipper, with a handle and a bowl that appear fainter and may be harder to spot in the night sky. Both constellations are actually part of Ursa Major and Ursa Minor, respectively.

A large piece of flat land is called a plain. A desert is a dry, barren area with little vegetation. A mountain is a raised landform with a peak or summit.

Earth rotates once every 24 hours. If you divide 8766.15 by 24, you get pretty close to the number of days in a year. __________ Not quite. 24 hours is the average synodic period of earth, not the rotational (sidereal) period. Earth rotates once every 23 hours, 56 minutes and 4.1 seconds roughly. This turns out to be about 23.93 hours. The orbital period of earth is 8766.152784 hours roughly. So the earth rotates (sidereal) about 366.325 times in a year. See discussion if you doubt this result.

The sun (and its system, including us) is moving in an orbit around the center of the Milky Way, and it is moving at the brisk rate of 486,000 miles per hour. It takes an unfathomable 226 million years for the sun (and its solar system) to make the full circuit around. The last time we were at this position was 226 million years ago, and dinosaurs ruled. The earth travels at 67,000 miles per hour in its orbit around the sun; a snail's pace compared to our galactic romp. See link.

The solid part of the Earth is called the lithosphere. It includes the crust and uppermost part of the mantle, and is divided into tectonic plates that float on the semi-fluid asthenosphere beneath them.
