Her muscles are going through a stage of anaerobic respiration called Lactic Acid Fermentation and are producing lactic acid due to the fact that there aren't enough oxygen molecules present. This is causing there to be much less ATP produced but at a quicker rate. Her soreness is due to the building up of lactic acid in her muscles.

Explanation:

Cell respiration has two categories, anaerobic and aerobic. Anaerobic respiration happens when there is no or not enough oxygen present to go through Aerobic respiration. When you're doing high energy activities (such as running), your body doesn't have enough oxygen to go through the full aerobic respiration process and resorts to anaerobic respiration which, for animals, ends with Lactic Acid Fermentation. Doing this produces quick energy with the downside of also producing lactic acid which causes soreness in muscles.

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.
