Poyasnenie:
Pochemu ten' etogo vulkana vyglyadit kak treugol'nik?
Sam vulkan Maunt Teide vovse ne imeet takoi pravil'noi
treugol'noi formy, kak mozhet pokazat'sya po vidu ego
piramidal'noi teni.
Odnako, pohozhee yavlenie treugol'nyh tenei harakterno ne
tol'ko dlya Maunt Teide. Takoe zrelishe
obychno mozhno uvidet' s vershin
vseh vysokih gor i vulkanov.
Klyuch k razgadke prirody takih neobychnyh tenei prost: nablyudatel', stoyashii na vershine, smotrit skvoz' dlinnyi koridor
teni ot zakata (ili voshoda), kotoryi tyanetsya do samogo gorizonta.
Dazhe esli by vulkan imel pravil'nuyu
kubicheskuyu formu, a ego ten' byla by dlinnym pryamougol'nikom, samyi
dal'nii konec etoi pryamougol'noi teni kazalsya by tochkoi. Tak na gorizonte shodyatsya vmeste
parallel'nye zheleznodorozhnye rel'sy.

Ryadom s zhivopisnoi ten'yu vidna pochti polnaya Luna srazu zhe posle svoego
polnogo zatmeniya, kotoroe proizoshlo v proshlom mesyace.
