A Land mass is large geographical area that is surrounded by oceans. Therefore this can be synonymous to continents.
Explanation:
The crust is divided into tectonic plates that are dynamic because they move on top of the semi-plastic mantle. The movement of the tectonic plates is driven by the convection currents of the mantle that drag along the crust above. The tectonic plates collide at convergent boundaries where tectonic plates are consumed as one is subsided into the mantle. On the other hand, new crust is formed at divergent boundaries where two tectonic plates move away from each other and magma rises from the mantle and cools into new crust.
The convection currents occurs because the lower mantle is hotter and less dense compared to the cooler denser upper mantle. Therefore the upper mantle always tends to sink as the lower mantle rises. These convection currents are the same as in any other fluids that are disproportionately heated.

Answer: No, only identical twins will look identical.
Explanation:
Identical twins are also called monozygotic twins. Such twins are produced by the fertilization of one egg that splits into two. The genes present in these twins are same thus the expression of traits is also same in them and they have the same sex.
Sam and Joe and Maria and Ella are identical twins these pairs are expected to have same genotypic and phenotypic traits. They may be clones of each other. But if Sam and Maria are married and Joe and Ella are also married then their children will have some similar traits in common but their children will not be identical as they are not identical twins as their parents were.
It is the circular pathway of water on the earth from the atmosphere, to the surface, to the ground, and back.
Respiration is the way that plants release water into the atmosphere.
