题目内容

【题目】下列自然资源,属于可再生资源的是

A.煤炭B.铁矿C.土地D.石油

【答案】C

【解析】

可再生资源是指被人类开发利用后,可以在较短时间内更新、再生,或者能够重复利用、循环使用的自然资源。非可再生资源是指经人类开发利用后蕴藏量不断减少,在相当长的时间内不可能再生的自然资源,主要是指自然界的各种矿物、岩石和化石燃料。据此判断,土地、风能、森林属于可再生资源,石油、天然气属于非可再生资源。

可再生资源是指被人类开发利用后,可以在较短时间内更新、再生,或者能够重复利用、循环使用的自然资源,如气候资源、生物资源、水资源和土地资源等。非可再生资源是指经人类开发利用后蕴藏量不断减少,在相当长的时间内不可能再生的自然资源,主要是指自然界的各种矿物、岩石和化石燃料,例如金属矿产、非金属矿产、煤炭、石油、天然气等矿产资源。所以ABD错误,C正确。故选C
