Tom qab ntawd, ib tug kuj yuav nug, dab tsi txheej ntawm huab cua kub tshaj?
thermosphere
Kuj Paub, qhov kub ntawm txhua txheej ntawm huab cua yog dab tsi? Lub mesosphere pib ntawm 31 mais (50 km) thiab txuas mus rau 53 mais (85 km) siab. Sab saum toj ntawm lub mesosphere, hu ua mesopause, yog qhov txias tshaj plaws ntawm lub ntiaj teb huab cua , nrog kub Qhov nruab nrab ntawm qhov nruab nrab yog 130 ° F (minus 90 C). Qhov no txheej nyuaj kawm.
Hauv qhov no, qhov twg ob thaj chaw atmospheric kub nce nrog qhov siab?
Hauv stratosphere , kub nce nrog qhov siab. Yog vim li cas yog qhov ncaj qha tshav kub qhov chaw rau lub stratosphere yog lub hnub. Ib txheej ntawm ozone molecules absorbs hnub ci hluav taws xob, uas heats lub stratosphere.
Cov huab cua theem twg tshwm sim ntawm qhov siab tshaj plaws?
Cov thermosphere yog txheej thib ob-siab tshaj plaws ntawm lub ntiaj teb huab cua. Nws txuas los ntawm mesopause (uas cais nws los ntawm mesosphere ) ntawm qhov siab ntawm 80 km (50 mi; 260, 000 ft) mus txog rau lub thermopause ntawm qhov siab ntawm 500–1000 km (310–620 mi; 1, 600, 000–3, 300, 000 ft).
