Planet Earth

The Earth is estimated to be around 4.54 billion years old.

Since people are both being born all the time and dying all the time, you can never get a precise figure for the global population at any given moment, however, the world's total population is currently (in the year 2012) approaching seven billion.

Planets in he solar sysem are shaped like spheres because The gravity of each planet makes sure that all the mass is equally distributed into a sphere like form.

Objects with no gravity like for example asteroids can appear in random clump shapes

The solar system consists of the Sun and eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), along with various smaller bodies like asteroids, comets, and moons. These objects orbit the Sun due to its gravitational pull, with each planet having its unique characteristics and orbit.

Other planets in our solar sustem besides earth have events such as huge storms, volcanoes, earthquakes and meteor bombardments, or have had them in the past. The question is though, are these disasters when there are no humans around to be effected by the events. I would suggest no, they are not since human lives are not effected.

Convection currents are circular movements of fluid driven by temperature differences. In Earth's mantle, convection currents occur in the asthenosphere, which is the semi-solid layer beneath the lithosphere. These currents play a significant role in plate tectonics and the movement of Earth's crustal plates.

The best way I can answer this for the Equinox is that the Earth's axis sits parallel to the sun. So both north and south poles are pointed straight up and down in relation to the sun. Thusly, the center of the sun being in the same plane as the Earth's equator.

The solstice is the opposite of the equinox. This is where one of the Poles are in the same plane as the sun.

Its hard to explain without a visual representation of the earth, the earths axis and their relation to the sun.

The Earth is composed of four main layers: the inner core, outer core, mantle, and crust. The outermost layer of the Earth is the crust, which is surrounded by the atmosphere (a thin layer of gases), and the hydrosphere (all of Earth's water bodies, such as oceans and lakes).

British King George V controlled the largest empire in history, known as the British Empire, which covered about 23% of the Earth's total land area at its height in the early 20th century.

Axis is tilted 23 and a half degree. This network of axis, latitudes and longitudes together form a criss-cross pattern called grid which is a network of these 3 things. Suppose if you want to locate California on a globe or a map, you just require its longitudenal and latitudenal value, by which you can locate the longitude and latitude on the globe, on the mark they will meet, you will have California there.

The sun warms the Earth's surface, atmosphere, and oceans. The sunlight is absorbed by the Earth's surface, causing it to heat up and then radiate heat back into the atmosphere. The atmosphere traps some of this heat, leading to the warming of the planet.

Earth and Mars have never collided. They are two separate planets in our solar system that orbit the Sun.

The earth is spining because it started to spin when the Eath was created. Since then not much has caused it to slow down since space is mostly a vacuum, so there isn't much friction to slow the planet down. Scientist say that since the world was created it's rotation time has slowed down by about 4 hour. i just copied and pasted this hope its helps xx

The closest star to earth is the sun. The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).

Venus is often referred to as Earth's sister planet because they are similar in size and composition. Both planets have rocky surfaces and are located in the inner solar system. However, Venus has a very different atmosphere, with extreme temperatures and a thick layer of clouds made of sulfuric acid.

Every meridian of longitude has the same nominal length, because all meridians

have the same end-points ... the north and south poles. So the length of a

meridian is half of the Earth's polar circumference ... 20,004 km (12,430 miles).

yes! besides light, meteorites and other small particles from outr space reach earth quite frequently

Particles and Objects from the outer space strikes the Earth all the time. It is estimated that more than 100 tons of material from outer space land on the Earth everyday. By far the majority of this material is comprised of little tiny bits of interplanetary dust that are smaller than grains of sand.

Other kinds of things hit Earth too, from subatomic particles (neutrinos and cosmic rays), to large pieces of rock and metal called meteorites. Long ago in Earth's history, very large impactors have struck as well; and billions of years ago, at least one protoplanet thousands of miles wide struck our planet. Many Scientists belive that this event caused the formation of our Moon.

In order of size from largest to smallest

Sun > Earth > Moon.

If we quote the radius of these objects.

Sun ; 695,700 km

Earth ; 6,365 km

Moon ; 1,736 km

From these figures you can see that the Sun is over 100 times bigger than the Earth, and the Earth is nearly 4 times greater than the Moon.

The reason why the Sun and Moon appear to the same size is because the Moon is much nearer to the Earth , than the Sun. It is a property of optics that the further away an object is, then the smaller it appears.

From the Earth;-

Sun's distance is ~92,000,000 miles

Moon's distance is ~242,000 miles.

From the above radii you can calculate the volume of each object. By using the Gravitational Constant the masses of these objects can be calculated.

The Coriolis effect is the name given to the force of the Earth's rotation that mainly affects air flow. It causes moving air or water to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Yes, earthquakes can occur on other planets and celestial bodies within our solar system. For example, Mars experiences Marsquakes, which are similar to earthquakes but caused by the planet's internal processes. Likewise, the moon is also known to have moonquakes, which are caused by the gravitational forces between the Earth and the moon.

No, gravity holds planets in orbit around the sun because the sun's gravity pulls on them. This gravitational force between the sun and planets keeps them in their respective orbits. The force between planets themselves is much smaller and mainly affects their interactions with each other rather than their orbits around the sun.

Venus is the planet closest to Earth in terms of temperature. It has an extremely hot and inhospitable surface due to its thick atmosphere, which traps heat and creates a greenhouse effect. This makes Venus hotter than even Mercury, the closest planet to the Sun.

The first total solar eclipse visible in Nigeria occurred on October 29, 1947. Places like Lagos, Kano, and Maiduguri experienced totality during this event.

Earth's unique combination of a breathable atmosphere, liquid water, and a stable climate is what allows for the diversity of life, including humans and microorganisms, to exist. These conditions are not found together on any other planet in our solar system. Additionally, Earth's distance from the Sun and its magnetic field play important roles in protecting life from harmful solar radiation.
