Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches. The descending end of the oceanic plate melts and creates pressure in the mantle, causing volcanoes to form. Back-arc basins can form from extension in the overriding plate, in response to the ...
A nail is a protective plate characteristically found at the tip of the digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals. . Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves and horns of ver
Double-ended nail – a rare type of nail with points on both ends and the "head" in the middle for joining boards together. See this patent. Similar to a dowel nail but with a head on the shank. Double-headed (duplex, formwork, shutter, scaffold) nail – used for temporary nailing; nails can easily pulled for later disassembly
These smaller plates are often not shown on major plate maps, as the majority of them do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km 2 (7.7 million sq mi) but greater than 1 million km 2 (0.39 million sq mi).
The Southeast Indian Ridge (denoted by the yellow line) The Southeast Indian Ridge (SEIR) is a mid-ocean ridge in the southern Indian Ocean.A divergent tectonic plate boundary stretching almost 6,000 km (3,700 mi) between the Rodrigues triple junction) in the Indian Ocean and the Macquarie triple junction) in the Pacific Ocean, the SEIR forms the plate boundary between the Australian and ...

The Caroline plate is a minor tectonic plate that straddles the Equator in the eastern hemisphere located north of New Guinea. It forms a subduction zone along the border with the Bird's Head plate and other minor plates of the New Guinea region to the south. A transform boundary forms the northern border with the Pacific plate.
Relief map with the East Pacific Rise (shown in light blue), extending south from the Gulf of California. The East Pacific Rise (EPR) is a mid-ocean rise (usually termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), at a divergent tectonic plate boundary, located along the floor of the Pacific Ocean.
