what is the main cause of global convection currents; in most cases a hurricane will; what are convection currents; what is convection in science
Uneven heating of the Earth by the sun is the main cause of global convection currents.
What are convection currents?Convection is a single- or multiphase fluid movement that develops on its own as a result of the interaction between a fluid's body forces—most frequently gravity and density—and material property heterogeneity. Convection currents are a type of natural heat transfer that involves the transmission of energy and heat from one location to another. Convection currents are to blame for this.
Warm air rising toward a home's ceiling or attic is a straightforward illustration of convection currents. Warm air is less dense than chilly air, hence it rises. Convection currents include the wind. Heat is radiated by sunlight or reflected light, creating a temperature difference that moves the air.

TRUE/FALSE. At depths below 100 km, subduction zone earthquakes occur almost exclusively in the interior of the colder oceanic lithosphere, the heart of the subducting slab.
TRUE. The crust or upper mantle, which extends from the surface of the earth to a depth of about 800 kilometers, is where earthquakes occur.
The strength of shaking at the surface from an earthquake that occurs at 500 km depth is significantly less than if the same earthquake had occurred at 20 km depth because the strength of shaking from an earthquake weakens with increasing distance from the earthquake's source.Additionally, the depths of earthquakes reveal vital details about the tectonic environment and the structure of the Earth. In subduction zones, where plates are colliding and one plate is being subducted beneath another, this is most obvious. We can see details of a subduction zone's structure, such as how steeply it dips and whether the down-going plate is planar or bent, by carefully plotting the location and depth of earthquakes connected to the zone.

We call these interconnecting pieces tectonic plates, and the edges of the plates are known as the plate limits. The plate limits are comprised of many issues, and the vast majority of the earthquakes all over the planet happen on these shortcomings. Since the edges of the plates are harsh, they stall out while the remainder of the plate continues to move.

indicate the order in which these seismic waves would arrive at a seismic station following an earthquake.
P waves arrive first because they move the most quickly. S waves arrive later because they move at a pace that is roughly half that of P waves. An earthquake's P and S waves are rapidly recorded by a seismic station nearby.
S waves are known as secondary waves because, at seismic recording sites, they invariably come after P waves. S waves, in contrast to P waves, can only pass through solid objects. Surface waves, that travel over the surface of the Earth, follow P & S waves after they have passed throughout the body of the planet.
The P waves advance steadily in front of the S waves as they leave the epicenter of an earthquake. As a result, the P and S waves will arrive at seismic recording stations at progressively different times depending on how far away they are from the earthquake epicenter.

Explanation:
The landforms which are created by erosional and depositional activities of wind are called as Aeolian Landforms.
Semi-arid environments, which are places with little precipitation and moderately dry conditions, are prone to wind erosion and deposition. In certain areas, wind can play a big role in sculpting the terrain and forming different geomorphic features.
Wind erosion is the process by which wind carries loose material from one place to another, including sand, dust, and soil. Sand dunes, sand sheets, and deflation hollows may develop as a result of this.
On the other side, the process by which wind drops or deposits the stuff it has been transporting is known as wind deposition. Features like sand bars, blowouts, and depositional ridges may result from this.
The velocity and direction of the wind, the kind, and size of the material being moved, the topography and vegetation of the area, as well as other variables, can all have an impact on wind erosion and deposition.
