What about the heights of planet Earth? A truly global response has been obtained through the Global Land One-km Base Elevation (GLOBE) project. The photograph above is the best digital orographic map ever made of the planet we live in, a map whose realization has taken more than ten years, incorporating data provided by several different countries around the world.

This view of the Earth rising above the horizon of the Moon was taken from the Apollo 11 spacecraft. The lunar terrain that can be seen corresponds to the Smyth Sea region on the near side of the Moon. From the lunar surface the Earth looks huge and you can see in detail, if the clouds allow it, the silhouette of the continents.
The impact of an asteroid or comet left hundreds of millions of years ago the scars on the landscape that are still visible on this radar image in an area of the Sahara Desert, north of Chad. The original crater was buried by sediments that were partially eroded to show the current appearance of rings.
Not far from Earth, at an average distance of 384,000 km., The Moon orbits, its only satellite. Because the diameter of the Moon with respect to that of our planet is just under 1/3, unusual for a satellite, some studies have hypothesized that the Earth-Moon system is a double planet.
An eclipse of the Sun is the total or partial obscuration of the Sun produced by the passage of the Moon between the Sun and the Earth. It is only visible in a narrow strip of the Earth's surface. When the Moon interposes between the Sun and the Earth, it casts a shadow on a certain part of the Earth's surface, and a certain point on Earth can be immersed in the shadow cone or the penumbra cone.
In the region of Patagonia, in Argentina, is the Perito Moreno glacier. It is an immense mass of ice located in the province of Santa Cruz. Because of its spectacular, and easy accessibility, it is one of the most visited places on Earth. It is considered as "the Eighth Wonder of the World".
This photograph shows the erupting Stromboli volcano, launching a true incandescent lava waterfall. Strombolian eruptions are characterized by an intermittent explosion of basaltic lavas in the form of a source, leaving a single crater. Each episode is caused by the accumulation of volcanic gases and they occur rhythmically sometimes and irregularly at other times.
When a small meteor hits Earth's ground, nothing much happens. The effect that it can produce on the earth's crust erodes rapidly and, after a short time, there is no trace left. However, about 50,000 years ago, a large meteorite hit the planet's ground hard and produced the Barringer meteor crater in Arizona, which shows this photograph.
The atmosphere is the gaseous envelope that surrounds the solid body of the planet. Although it has a thickness of more than 1,100 km, approximately half of its mass is concentrated in the lowest 5.6 km. The Earth is a planet endowed with a rich atmosphere, to which we owe the birth and development of life.
With the name of ocean, the large volumes of water on the Earth's surface are called. There are three large oceans, the Atlantic, the Indian and the Pacific, the latter being the largest. It occupies 165,700,000 square kilometers of area, that is, one third of the earth's surface.
The relief forms are determined by the composition and lithological structure, and by the processes that led to its genesis. The photograph above is one of the best maps of the earth's crust ever made of the planet we live in. The map incorporates data provided by several different countries around the world.
This photo was captured when tall, thin clouds containing millions of ice crystals covering much of the sky. Each of the ice crystals acts as miniature lenses. This occurs because most of these crystals have an elongated hexagonal shape and the light that enters through one of the faces of these crystals is refracted on its opposite side just at 22 degrees, which corresponds to the radius of the lunar halo.
On the Apollo 17 mission, in 1972, American astronaut Harrison Schmitt explored the lunar surface firsthand. This mission took extraordinary photographs of the Earth, from its natural satellite, the Moon. In this panoramic view of the Moon, built from the photos taken by astronaut Eugene Cernan, the magnificent desolation of the sterile lunar landscape is evident.
One of the most outstanding craters on our Moon is called Copernicus. Copernicus is a young, large, visible crater with binoculars a little to the northwest of the center of the visible hemisphere of the moon. Copernicus is distinguished by its size and the numerous bright rays that come out of it.
This might look like a bright star appearing behind the Moon, but no, it's about the planet Mars. The red planet passed near the waning moon and could be seen from some locations in Central and South America, the Caribbean and Florida. The expedition of the Clay Center Observatory to Bonita Springs, Florida, resulted in this evocative image of Mars peeking over the dark edge of the moon, after digitally processing and grouping several series of telescopic images of the event.
The Apenninus Mountains are a prominent mountain range located in the northern hemisphere of the Moon. This great mountain range borders the southern part of the Mare Imbrium, while in the north it forms a border with the northern regions of Terra Nivium. The Apenninus mountains start next to the Eratosthenes crater, and end next to the Promontorium Fresnel.
The NASA Lunar Prospector probe made an approach to closely observe the moon. The mission entered a longer phase, and the controllers reduced the altitude of this lunar orbiter from 100 to 30 kilometers, allowing spectacular and very detailed photographs, such as this one. Global properties have already been observed and evidence of the existence of water ice in the lunar poles.
The full moon in its perigee (the closest point of its orbit) and its peak (the farthest). The photo shows a comparison between the different sizes visible from Earth. This illustration, based on the images of the Galileo probe, shows the approximate difference in the apparent size between a full moon in perigee (on the left) and the full moon at its peak (on the right), the furthest points in the lunar orbit
The process of breaking the wave involves the release of its energy. The way in which the wave breaks, the type of breaking wave resulting and the ability to break and modify the coastline depend on the initial height of the wave and the slope of the cliff. Erosion caused in coastal areas by sea waves forms the abrasion coasts, which are continuously excavated by waves.
As expected, the ozone hole near the Earth's South Pole, grew again during 2003. This year's hole, slightly larger than North America, is larger than last year, but smaller than the record reached on September 10, 2000. Ozone is important because it protects us from the damage of ultraviolet radiation from sunlight.
Planet Earth The Earth is the only planet in the solar system where we know for sure that life exists. It is natural, it is our planet.
