Explanation:
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.
Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]
Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence
With this x and y pair they are male
1. Answer:
Both these leaves are quite similar because of their physical appearance. <em>The sea teak leaf and weeping willow leaf are narrow and elongated. However, a weeping willow leaf has tapered edges.
</em>
The scientific names of sea teak and weeping willow plants are Podocarpus polystachyus and Salix babylonica.
- The leaves of both these plants are simple regardless of their receptive compound appearance. This is due to the presence of complex vein structure on the leaf.
2. Answer:
<u>There many differences between sea teak leaf and weeping willow leaf.</u>
Sea teak leaf is 3-10 cm long while weeping willow leaf is only 6 cm long.
Sea teak leaves are bright green and shiny while weeping willow leaves are green at top and white at the bottom.
<em>The bark of weeping willow can be used to obtain various medicines. Meanwhile, the leaves of sea teak plants are chewed to ease pain of joints.
</em>
<u>Weeping willow trees are found in areas of China, South-West Asia and Europe.
</u>
<u>Sea Teak trees are found in Indonesia, Malaysia etc.</u>
