ʻOkoʻa ka lewa o ka Honua ʻaʻole wale i kāna haku mele ʻana, akā i kāna mea nui no ka helehelena o ka honua a me ka mālama ʻana i ke ola. Aia ka lewa i ka oxygen e pono ai no ka hanu ʻana, mālama a hāʻawi hou i ka wela, a lawelawe ʻia ma ke ʻano he pale hilinaʻi mai nā kukuna cosmic weliweli a me nā kino lani liʻiliʻi. Mahalo i ka lewa, ʻike mākou i nā ānuenue a me nā aurora, mahalo i nā puka ʻana o ka lā a me nā napoʻo ʻana o ka lā, e ʻoliʻoli i ka lā palekana a me nā ʻano hau. ʻO ka mana o ka lewa ma kā mākou honua he nui a ākea āpau i kēlā me kēia ʻano noʻonoʻo e pili ana i ka mea e hiki ke hana inā ʻaʻohe ʻano lewa - ma kēia hihia ʻaʻohe mea. Ma kahi o nā mea i haku wale ʻia, ʻoi aku ka maikaʻi o ka hoʻomaʻamaʻa ʻana me kekahi mau waiwai o ka lewa o ka honua.
1. Ma kahi e hoʻomaka ai ka lewa, ʻike ʻia - kēia ka ʻili o ka Honua. Akā ma kahi e pau ai, hiki i kekahi ke hoʻopaʻapaʻa. ʻIke ʻia nā moleola ea ma kahi kiʻekiʻe o 1,000 km. Eia naʻe, ʻo ke kiʻi i ʻae ʻia e 100 km - i kēia kiʻekiʻe, lahilahi ka lewa i hiki ʻole i nā lele e hoʻohana ana i ka ikaika hāpai o ka ea.
2. 4/5 o ke kaupaona o ke ea a me 90% o ka mahu wai i loko o ia mea i loko o ka troposfer - ka ʻāpana o ka lewa i kū pono i ka ʻili o ka Honua. I ka huina, mahele ʻia ka lewa i ʻelima mau papa.
3. ʻO Auroras nā collision o nā huna o ka makani lā me nā iona i loko o ka thermosphere (ʻo ka papa ʻehā o ka envelope kinoea o ka Honua) ma kahi kiʻekiʻe o 80 km.
4. ʻO nā iona o nā papa o luna o ka lewa, i hoʻohui ʻia i ka hōʻike o ka aurora borealis, he mea nui i hana nui. Ma mua o ka hiki ʻana mai o nā ukali, hāʻawi wale ʻia ke kamaʻilio lekiō e nā hiʻohiʻona he nui o nā nalu lekiō (eia kekahi, ma kahi o 10 m ka lōʻihi) mai ka ionosfer a me ka ʻili o ka honua.
5. Inā ʻoe e kaomi i ka lewa holoʻokoʻa i ka kaomi maʻamau ma ka ʻili o ka Honua, ʻaʻole e ʻoi aku ke kiʻekiʻe o kēlā envelope pēpē ma mua o 8 km.
6. Ke loli nei ke ʻano o ka lewa. ʻO 2,574 mau makahiki i hala aku nei, ʻo ka helium a me ka hydrogen ka mea nui. ʻO ka ʻoniʻoni, nā kinoea kaumaha i kipaku iā lākou i ka lewa, a ua hoʻomaka ka amonia, ka mahu wai, ka methane a me ka carbon dioxide e hoʻokumu i ke kumu o ka lewa. Ua hana ʻia ka lewa hou me kona momona me ka oxygen, i hoʻokuʻu ʻia e nā meaola ola. Ua kapa ʻia pēlā tertiary.
7. Hoʻololi ka hoʻonui ʻana o ka oxygen i ka lewa me ke kiʻekiʻe. Ma kahi kiʻekiʻena o 5 km, hoʻemi kona ʻāpana i ka lewa i hoʻokahi a me ka hapalua manawa, ma kahi kiʻekiʻe o 10 km - ʻehā mau manawa mai ka maʻamau ma ka papa honua.
8. Loaʻa nā koʻohune i ka lewa i nā kiʻekiʻe a i 15 km. E hānai ai i kahi kiʻekiʻe, ua lawa kā lākou meaola i ka hoʻohui ʻana o ka ea lewa.
9. ʻAʻole hoʻololi ka lani i kona kala. Ma ka ʻōlelo koʻikoʻi, ʻaʻohe ona loaʻa iki - aniani ka lewa. ʻO ke kihi wale nō o nā kukuna o ka lā a me ka lōʻihi o ka nalu kukui i hoʻopuehu ʻia e nā mea o ka lewa e loli. ʻO ka lani ʻulaʻula ma ka auwina a wanaʻao paha ka hopena o nā mea particulate a me nā kulu wai i ka lewa. Hoʻopuehu lākou i nā kukuna o ka lā, a ʻo ka pōkole o ka lōʻihi o ke kukui, ʻoi aku ka ikaika o ka pīpī. ʻO ke kukui ʻulaʻula ka lōʻihi lōʻihi lōʻihi, no laila, ke hele nei i loko o ka lewa a ma kahi kihi loa, ua liʻiliʻi ia ma mua o nā mea ʻē aʻe.
10. ʻIke like ke ʻano a me ke ānuenue. I kēia hihia wale nō, hoʻopili ʻia nā kukuna māmā a hoʻopuehu ʻia, a hoʻopili ka lōʻihi o ka nalu i ka huina hoʻolahalaha. ʻO nā ʻulaʻula māmā e nā 137.5 kekelē, a me ka viole - ma ka makahiki 139. Ua lawa kēia mau kekelē a me ka hapa e hōʻike iā mākou i kahi hanana kūlohelohe a e hoʻomanaʻo iā mākou i ka makemake o kēlā me kēia mea hahai holoholona. ʻO ka ʻāpana luna o ke ānuenue he ʻulaʻula mau ia a he poni ka lalo.
11. ʻAʻole kū ka Honua o ko mākou honua i ka Honua ma waena o nā kino lani ʻē aʻe (i ka ʻōnaehana o ka lā, ʻaʻohe o ka enope enehana ma kahi kokoke loa i ka Sun Mercury). ʻO ke kū hoʻokahi o ka Honua ke kū i ka lewa o kahi nui o ka oxygen manuahi a me ka hoʻopiha hou ʻana o ka oxygen i loko o ka envelope kinoea o ka honua. Ma hope o nā mea āpau, hana nui ʻia nā kaʻina hana ma ka Honua me ka hoʻohana ʻana o ka oxygen, mai ka puhi ʻana a me ka hanu ʻana i ka meaʻai popopo a me nā kui kui. Eia nō naʻe, kūpaʻa mau ka oxygen ma ka lewa.
12. Hiki ke hoʻohana i nā paio a nā jetliners e wānana i ke anilā. Inā haʻalele ka mokulele ma hope o kahi mānoanoa, wehewehe maikaʻi ʻia o ke keʻokeʻo, a laila ua paha. Inā aniani a maopopo ʻole ka contrail, e maloʻo ia. Pili ia i ka nui o ka mahu wai i ka lewa. ʻO lākou ka mea, e kāwili pū ana me ka ʻenekini hoʻopau, e hana i kahi keʻokeʻo keʻokeʻo Inā he nui ka mahu wai, ʻoi aku ka nui o ka contrail a ʻoi aku ke kiʻekiʻe o ka hiki o ka ua.
13. ʻO ke kū ʻana o ka lewa i ka palupalu i ke aniau. Ma nā panakō i nele i ka lewa, nā ʻokoʻa ma waena o ka mahana a me ka mahana o ka mahana a hiki i ka ʻumi a me nā haneli haneli. Ma ka Honua, hiki ʻole kēia mau ʻokoʻa ma muli o ka lewa.
14. Kuhi ka lewa i pale pale hilinaʻi mai ka radiation cosmic a me nā mea paʻa e hōʻea ana mai kahi ākea. ʻAʻole hiki ka hapa nui o nā meteorite i ka papa o kā mākou honua, e ʻā ana i nā papa o luna o ka lewa.
15. Ua hōʻike ʻia ka huaʻōlelo "palapala ozone" i ka lewa i ka makahiki 1985. Ua ʻike nā ʻepekema Pelekane i kahi puka o ka ozone layer o ka lewa. Pale ka pale ozone iā mākou mai ka pāhawewe ultraviolet paʻakikī, no laila ua kani koke ka lehulehu i ka pū waikaua. Ua wehewehe koke ʻia ka helehelena o ka lua e ka hana a ke kanaka. ʻO ka leka e hōʻike ʻia ai ka lua (aia ma luna o Antarctica) i kēlā me kēia makahiki no ʻelima mau mahina, a laila nalo, nānā ʻole ʻia. ʻO nā hopena i ʻike ʻia o ke kaua kūʻē ʻana i ka lua ozone ka pāpā o ka hoʻohana manuahi ʻana i nā pahu hau, nā ea a me nā aerosol a me ka hoʻēmi iki ʻana i ka nui o ka lua ozone.
