What if I told you that you can walk from North America to Europe in 20 mins? Well the answer is "Yes you can" if you are at Thingvellir National Park in Iceland. The only place on Earth where where the North American and Eurasian tectonic plates meet or rather move away from each other.

Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth's internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.
The tectonic plates whose turbulent interactions formed Iceland, are the Eurasian tectonic plate and the North American tectonic plate. Spanning the Mid-Atlantic Ridge, Iceland emerged as a result of the divergent, spreading, boundary between these two plates and the activity of Iceland´s own hotspot or mantle plume.
Divers swim in the space between North America and Europe. This location, between the continents, is located in Iceland's Thingvellir Lake. The Silfra fissure is the name of the crack between the two continents. It is the only spot in the world where you can swim between two continental plates.
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
Iceland was formed from volcanic eruptions on the Mid-Atlantic ridge. Iceland was formed for about 24 million years. Iceland is the only place where you can stand on the ridge on dry land. And that can trigger volcanoes or earthquakes.
Iceland is divided by the Mid-Atlantic Rift; some parts of it, such as the Westfjords and Reyjavík, are on the North American tectonic plate, while others, such as Vatnajökull glacier and the East Fjords, are on the Eurasian plate.
The Blue Lagoon is a geothermal spa in southwestern Iceland. The spa is located in a lava field near Grindavík on the Reykjanes Peninsula, in a location favourable for geothermal power, and is supplied by water used in the nearby Svartsengi geothermal power station.
There is no water under the continents. There is liquid rock under the continents; this is called the Earth's mantle. The hard parts of the Earth's crust are not literally floating on a surging sea down there. "Earth's crust "floats" on the hot, molten layer of the mantle.
Swim between two tectonic plates. Iceland's Silfra fissure is one of the only places where you can dive between two continents. In some cases the space is so narrow, you can touch North America and Europe at once.
Although there is plenty of life in Silfra, most of it is either plant life or microinvertibrates, which are not visible with the human eye. Throughout the rest of the year, the only fish who live in the Silfra fissure are the Dwarf Char, a subspecies of the Arctic Char.
Mid-ocean ridges are gaps between tectonic plates that mantle the Earth like seams on a baseball. Hot magma wells up at the ridges, forming new ocean crust and shoving the plates apart. At subduction zones, two tectonic plates meet and one slides beneath the other back into the mantle, the layer underneath the crust.
Africa is an amazing continent that is distinctly unique among the seven continents. Africa is rich in cultural heritage and diversity, a wealth of natural resources, offers breathtaking tourist attractions, and contains some of the most intricate political systems.
The continents do not float on a sea of molten rock. The continental and oceanic crusts sit on a thick layer of solid rock known as the mantle. Under the continents is a layer of solid rock known as the upper mantle or asthenosphere.
The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge.
Istanbul is one of the few cities in the world to be shared by two continents. Examples of other cities that are half-European and half-Asian include the Russian cities of Orenburg and Magnitogorsk, and Atyrau, a city in western Kazakhstan.
Most of the earthquakes detected in Iceland take place in one of the active volcanic zones or along the South Iceland Seismic Zone. Other types include quakes caused by changes in geothermal activity.
Two hours is probably enough unless you really fall in love with the place. The most interesting part is the beginning, and rest is lovely (waterfall, church, etc.)
The crust is made up of different types of rocks: igneous, metamorphic, and sedimentary rocks. Below the crust is the mantle. The crust and the upper mantle make up the lithosphere. One is the continental crust (under the land) and the other is the oceanic crust (under the ocean).
The Ring of Fire was formed as oceanic plates slid under continental plates. Volcanoes along the Ring of Fire are formed when one plate is shoved under another into the mantle -- a solid body of rock between the Earth's crust and the molten iron core -- through a process called subduction.
The state of Texas is located on top of the North American tectonic plate.
Tectonic plates move because they are floating on top of the mantle. The mantle itself moves due to convection currents: hot rock rises, gives off some heat, then falls. This creates vast swirls of moving rock under the crust of the earth, which jostles the plates of crust on top.

The Golden Circle (Icelandic: Gullni hringurinn) is a tourist route in southern Iceland, covering about 300 kilometres (190 mi) looping from Reykjavík into the southern uplands of Iceland and back. It is the area that contains most tours and travel-related activities in Iceland.
