Which is one way that chemical weathering influences mechanical weathering? A. Ice wedging breaks apart rocks, thereby exposing

them to acids in the rain. B. Plants secrete acids that create holes in rocks, thereby allowing water to penetrate for ice wedging. C. Water freezes in cracks of the rocks, thereby breaking them apart and the wind blows them away. D. Winds scrape the rock layers away, exposing them to acids in the rain.

What are convergent boundaries?
boyakko [2]

Answer:

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

Which characteristic best distinguishes runoff and infiltration?
Sever21 [200]

The right option is; d. Runoff describes water movement and infiltration describes water storage.

Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.  

Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.

This phylogenetic tree illustrates the evolutionary relationships of tetrapods and was constructed using both anatomical and DNA
AleksAgata [21]

Answer:

Mammals are more closely related to birds because they share a more recent common ancestor.

Explanation:

A tree diagram that represents hypothesised phylogenetic relationship illustrating evolutionary relationships among various entities (most often taxonomic groups) that are known to share a common ancestor.

An ancestors is one from whom a person is descended, whether on the father's or mother's side, at any distance of time; a progenitor; a forefather.

B. Mammals are more closely related to birds because they share a more recent common ancestor
