Earthtopomaps – Cape Verde Archipelago the island chain – 3D

Earthtopomaps – Cape Verde Archipelago the island chain

Despite the islands’ varied appearances, geologists surmise that all of the islands are volcanic in origin, sitting over a hotspot where magma pushes up through the Earth’s crust and erupts on the sea floor.

The island chain includes a variety of terrain and vegetation. On islands in the east Boa Vista and its neighbors earth tones predominate. These islands are generally flat with little fresh water. In the west, more mountainous islands boast more abundant greenery.

The highest point in Cape Verde is in the southwest: the volcanic summit of Fogo at 2,829 meters (9,281 feet).

The Cape Verde Archipelago lies some 650 kilometers (400 miles) off the coast of Senegal.

Against a navy background, the brown and green islands roughly form the shape of a giant V turned on its side.

Probably the best-known example of a hotspot is Hawaii. On a fast-moving plate, the Hawaiian Islands show a clear linear progression in age, with old Kauai in the northwest and young Hawaii ( Big Island ) in the southeast. Cape Verde, however, is roughly stationary with respect to the mantle plume responsible for its growth. As a result, the ages of the islands lack the same clarity as in Hawaii. In general:. Cape Verde islands appear oldest in the east ( Boa Vista and its neighbors ) and youngest in the northwest and southwest.

Volcanic activity is not the only force shaping Cape Verde. Just as magma elevates landmasses, relentless winds grind them down. Winds blow often over Cape Verde, and the winds frequently carry heavy loads of Saharan dust. Wind erosion may be more apparent along the islands from Boa Vista to Santo Antão, which bear the brunt of Saharan winds.

Earthtopomaps – Tiny Beetles Take a Large Bite Out of the Forest

)Earthtopomaps – Tiny Beetles Take a Large Bite Out of the Forest

A single pine bark beetle is about the size of a grain of rice. But when the beetle population swells, it can have a major impact on forest health. And that’s exactly what has been happening across the Rocky Mountains over the past decade.

In Colorado, severe beetle infestations showed up in lodgepole pine forests about 50 miles west of Boulder and Fort Collins around 2000.

Over time, the affected area grew so that by 2011 the infestation had spread east to ponderosa pine forests that were much closer to the two cities. (A map showing the progression between 1998 and 2011 is available here).

The beetle epidemic caused so many trees to die-off that the impacts are visible from space. The Thematic Mapper on Landsat 5 acquired these images of lodgepole pine forests near Grand Lake, Colorado on September 11, 2005, and September 28, 2011 before and after a severe infestation led to die-off of the tree canopy.

Over six years, beetle activity turned entire ridges and valleys brown.

Forest die-off is most visible in the center of the image and along both sides of the Kawuneeche Valley. The brownest areas in the 2011 image are generally stands of lodgepole pine, a slender tree that grows at 6,000 to 11,000 feet (1,800 to 3,300 meters) in elevation. Either spruce or aspen dominates the green areas that escaped infestation:. Such as the forests near Gravel Mountain and areas west of the Kawuneeche Valley.

It has been suggested that all the dead needles and trees trunk left after a beetle infestation must make wildfires more common and severe.

It wasn’t uncommon for beetles to get the blame for exacerbating the destructive High Park fire that raged near Fort Collin in June 2012.

However, Bill Romme, a Colorado State University professor who has studied the relationship:. Is not convinced. “Most research indicates that there is little or no such relationship between beetle-caused tree mortality and subsequent fire occurrence and severity in lodgepole pine forests,” he noted in an email. “Fire occurrence and severity in these forests are controlled primarily by weather conditions. Variation in fuel conditions, such as that introduced by the beetles, is a secondary and generally minor influence on fire behavior.”

Not all of the browning is due to beetles. In the upper central and lower right of the image:. Logging has also had an impact. And despite the beetle damage to the upper canopy, the forests are anything but dead. Even in the most severely affected areas:. Large numbers of trees survive.

Researchers do think pine beetles can affect the risk of severe fires, but the impacts are not always straightforward.

The most dangerous fires crown fires leap from treetop to treetop in an explosive wall of flame:. Rather than creeping along the ground surface. For the first few years after an infestation:. Beetle-impacted forests may have an increased risk of crown fires due to the dry needles that remain clinging to the tops of dying trees. But as these needles and other debris drop to the ground:. The risk of crown fires drops as well. According to one study, forest die-off from pine beetles infestations can reduce the risk of crown fires for decades by thinning forests.

This 4K visualization shows the of the aurora borealis of Earth

Among the views of Earth afforded astronauts aboard the International Space Station, surely one of the most spectacular is of the aurora.

Which layers shows the presence of aurora borealis ?

The thermosphere’s temperature is greatly influenced by solar activity. Finally, the thermosphere is where the aurora ( Southern and Northern Lights ) occur. At high latitudes, charged particles from space clash with atoms and molecules in the thermosphere, causing them to be excited into higher energy levels.

Where on Earth can you see the aurora borealis ?

Large Image: 4928 px X 3280 px ( click on the image to enlarge )

The northern lights most commonly occur within the geographic area beneath the auroral oval. It encompasses latitudes between 60 and 75 degrees and takes in Iceland, northern parts of Sweden, Finland, Norway, Russia, Canada and Alaska as well as southern Greenland.

Can you see aurora borealis on Google Maps ?
