What gives earth its extraordinary blue colour?
The Earth's atmosphere scatters sunlight in all directions, but it scatters shorter blue wavelengths more effectively than longer red wavelengths. This is known as Rayleigh scattering, and it is why the sky appears blue to our eyes. When we view the Earth from space, this scattered blue light gives our planet its overall blue appearance.
What is happening to earths average tempretature?
Earth's average temperature is increasing due to human activities that release greenhouse gases into the atmosphere, leading to the greenhouse effect. This phenomenon traps heat on Earth, causing global warming and resulting in various climate change effects like rising sea levels, more frequent extreme weather events, and changing wildlife habitats.
What does earths rotation control?
Earth's rotation controls the length of a day, causing the sun to rise and set. It also influences the planet's weather patterns, ocean currents, and the Coriolis effect, which affects winds and ocean circulation. Furthermore, the rotation helps provide the conditions necessary for life to exist on Earth.
What planet is about 10 times as far as earth from the sun?
The closest would probably be Saturn, which has a diameter of around 120 536 km, which is 9.45x Earth's diameter (12 756.2 km). The next closest is Jupiter, with a radius of 142 984 km, or 11.2x Earth's diameter.
Which layer of the earth contains the most silica?
The mantle layer contains the most silica. Silica is a major component of the minerals forming the mantle, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
What is the maximum and minimum distance between Earth and Jupiter?
The maximum distance between Earth and Jupiter is about 601 million kilometers when they are on opposite sides of the Sun (opposition). The minimum distance is around 588 million kilometers when they are on the same side of the Sun (conjunction).
How is the environment on the planet earth like?
The environment on planet Earth is diverse, with various ecosystems that support a wide range of plant and animal life. It faces challenges such as climate change, deforestation, and pollution that impact its delicate balance. Efforts are being made globally to protect and preserve the environment for future generations.
How do you know that the earth is covered with water?
Scientists have used various methods, including satellite observations and direct measurements, to estimate that Earth's surface is approximately 71% covered by water. This calculation takes into account the vast oceans, seas, lakes, rivers, and ice caps that make up Earth's water bodies.
How far is Draco away from Earth?
Draco is a constellation located in the northern sky. It is approximately 309 light-years away from Earth.
It seems like there is a typo in your question. Could you please clarify what you mean by "conitnet"?
How many total of human beings are the on earth?
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.
Is the planet Earth shaped like a sphere?
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
What is earth and 8 other planets and thousands of smaller bodys that all revavle around the sun?
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.
What are convection currents and in which layer do they occur?
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.
What is the circumference of the Earth?
The equatorial circumference of the Earth is about 40,075 km (24,901 m).
The polar circumference of the Earth is about 40,008 km (24,860 m).
More Precisely:
Earth is not a perfect sphere, but is "flattened" at the poles. Its shape is described as an oblate spheroid. So, the Earth's circumference is about 68 km (41 m), larger around its bellythan around its poles.
This difference is small enough that, were the earth shrunk down to the size of a billiard ball, it would be more perfectly round than most billiard balls.
Caveat: The numbers for circumference are always approximations because Earth's surface is irregular and constantly changing. The tidal bulging (constantly shifting) is a dynamic factor. Polar measurements vary with longitude. So these approximations can differ by a kilometer or two.
How does the position of Earth determine weather a day is one of the solstice or equimox days?
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.
What is the earth made up of what surrounds it?
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).
What king controlled more of the earths surface than any other man?
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.
How is the axis of the earth useful in locating placec on the globe?
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.
What parts of earth does the sun warms?
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.
When did earth and mars collided?
Earth and Mars have never collided. They are two separate planets in our solar system that orbit the Sun.
What causes the world to go round?
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
Which is the closest star to earth not counting the sun?
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).
