Hi the answer to your question would be, Theremohaline circulation is mostly driven by global density gradients created by surface heat. So, deep ocean currents are caused by the water's density, which is controlled by the temperature (greek word thermo) and salinity (haline). This is thermohaline circulation described. Now once the sea water gets more saltier and then ice forms some salt is left behind and then density increases & starts to sink. Now surface water comes in to replace the sinking water & the temperature drops and then it becomes cold & salty enough to sink. This initiates the deep ocean currents which drives the global conveyor belt. Let me know if you need me to explain more. Hope this helped :)
<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>
Answer:
Increase EDV and therefore, increase stroke volume.
Explanation:
EDV is the volume of blood which filled the ventricle before its contraction while ESV is the volume of blood remain in ventricle after ejection.
When venous return increases, this will increase the pressure on ventricle contraction which can lead to eject of addition blood returned to it.
So, increase in EDV results in an increase of stroke volume (SV).
Answer:
cooling of lava or magma makes igneous
sedimentary rock is formed when sediment gets deposited, and is hardened by compaction and cementation.
any rock can turn into a metamorphic rock when exposed to extreme heat and pressure
