Phases of the moon
In the northern hemisphere, if the left side of the Moon is dark then the light part is growing, and the Moon is referred to as waxing (moving toward a full moon). If the right side of the Moon is dark then the light part is shrinking, and the Moon is referred to as waning (past full and moving toward a new moon). A gibbous moon is a convex at bothedges, as the moon when more than half full. A crescent moon is part way between a half moon and a new moon, or between a new moon and a half moon. FULL MOON. A full moon appears as an entire circle in the sky. The waxing moon keeps growing to the right and the waning moon shrinks to the right. Lunar cycles are 29 days, the lunar cycle is the same as a moon cycle with the same moon cycles.
Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century. Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart. A convergent also known as a destuctive plate boundary (because of subduction) is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide. A divergent in plate tectonics is a divergent plate boundary also known as a constructive boundary or an extensional is a linear feature that exists between two tectonic plates that are moving away from each other. Places where plates slide past each other are called transform boundaries. Since the plates on either side of a transform boundary are merely sliding past each other and not tearing or crunching each other, transform boundaries lack the spectacular features found at convergent and divergent boundaries.
Juan De Fuca is the name of the fault line off the coast of Washington and Oregon. The cascades are The continental margin and the Juan de Fuca plate are breaking up into smaller crustal blocks that are being dragged northward by the motion of the Pacific plate. Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries. A large area of the earth in which plates of the earth's crust are moving away from eachother, forming an extensive system of fractures and faults. A subduction zone is the biggest smash-up on Earth, marking the collision between two of the planet's tectonic plates, the pieces of crust that slowly move across the surface over millions of years. The Channeled Scablands were formed over millions of years.
