Interesting question!
以下说法我觉得有点靠谱：
A canyon is a narrow chasm with steep cliff walls, cut into the earth by running water; a gorge usually formed by the down-cutting of a river in a dry area where there is insufficient rainfall to erode the sides.
A valley is an elongated lowland between ranges of mountains, hills, or other uplands, often having a river or stream running along the bottom; also an extensive area of land drained or irrigated by a river system.
Canyons have steep, cliff-like walls or sides, while valleys have gently sloping sides.
也就是说从两岸山体的形状来判断是valley还是canyon，canyon两岸通常是陡峭的悬崖。
valley和mountain的区别：意思不同、读音不同。
valley
英 ['væli] 美 ['væli]
n. 山谷；溪谷；流域。
mountain
英 ['maʊntən] 美 ['maʊntən]
n. 大量；山；山脉；高山。
mountain是可数名词,意思是“山,高山”,通常指较陡峭的高山; mountain的复数形式可表示“山脉”或“山区”。
用于专有名词时,山名须置于mountains之前,且须加定冠词。
mountain可用在另一个名词作前定语。
valley的基本意思是“谷,山谷”,指两山之间通常有水流的地段,其前多用定冠词。
valley经常引申为工业或整体经济发展过程中的“低谷区”。
valley 是山谷的意思，两山丘之间的低地，有小溪穿过。
形象记忆：首字母 V就是一个形象的 “山谷的样子”。
词根记忆：val的词根是“强壮、有价值的意思”，可以联想 value,价值
value valley有价值的是山谷，因为必有“小溪”，可避暑、可饮水。
谐音记忆：“威力” ，山谷之所以有地势上的威力，因为有水，地势险要。
The simplest way to answer this is to define each term,so you can see:
A canyon is a deep valley with steep sides,think of the grand canyon most famously to visualise what this is.
A gorge is a deep ravine,which usually has a river running through it - though this doesn't have to be the case.
Finally a valley is any depression,usually of a certain length,in the surface of the land and often contains a river.
So,a canyon is a specific type of valley,with particularly steep sides.A gorge is a particularly deep depression,and will usually contain a river.
Canyon and gorge are somewhat interchangeable,depending on regional semantics,and describe a condition of land scoured or carved out by rivers (or wind),creating deep gouges in the earth of varying depths.A valley is usually a discernable low spot in the land,probably created by tectonic action or glacier movement.
正好我也在找这几个的区别,找到些自己看了顺便就贴一份,

valley n.山谷、流域、溪谷，来自古法语valee，来自拉丁语vallis，表示峡谷，比如美国加州高科技公司云集的the Silicon Valley硅谷和盛产葡萄酒的Napa Valley纳帕溪谷，再比如孕育了最早人类的The Great Rift Valley东非大裂谷。其实英语中有不少表达山谷、峡谷之类概念的单词，它们之间是有细微的差别的，比如：
gorge n.山峡、峡谷、咽喉，如长江流域的the Three Gorges三峡；
canyon n.峡谷，如美国举世闻名的the Grand Canyon大峡谷；
dingle n.峡谷、幽谷，通常被茂密的森林植被覆盖；
ravine n.沟壑、峡谷、山涧（多是被雨水等破坏和蹂躏后形成），想象下沟壑纵横的黄土高原。
