molten rock from a volcano
Very hot, liquid rock that comes out of a volcano onto the ground.
用法模式：
lava flows down [a volcano]
常见错误：
Learners sometimes confuse ‘lava’ with ‘magma’. ‘Magma’ is molten rock under the ground, and it is called ‘lava’ only after it comes out of a volcano. Also, ‘lava’ is usually used as an uncountable noun, so we normally say ‘some lava’ or ‘a lot of lava’, not ‘*two lavas’ in general descriptions.
近义词
molten rock (More descriptive and technical; clearly states that the rock is in liquid form.)

magma (Scientific term for molten rock below the Earth’s surface; becomes lava only when it erupts outside.)
反义词
solid rock (Refers to rock in a hard, non-liquid state, the opposite physical state of molten lava.)

rock formed from cooled lava
Hard, black or dark rock that was once hot lava but has cooled and become solid.
用法模式：
walk on [cooled] lava
常见错误：
Learners may think ‘lava’ always means hot, liquid rock. It can also mean the hard rock after it cools, especially in phrases like ‘lava rock’, ‘lava field’, or ‘old lava’. Context and adjectives such as ‘hot’ or ‘cooled’ help show which meaning is intended.
近义词
lava rock (Informal everyday term that clearly refers to the solid rock formed from cooled lava.)
|
basalt (A specific common type of dark volcanic rock; more technical and not all cooled lava is basalt.)
反义词
molten lava (Describes the same material in its hot, liquid state, which is the opposite of cooled, solid lava rock.)
搭配

|solidified lava
|lava rock
|lava field
