I think it is your thesis
Answer:
Convection current
Explanation:
Convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air, the cold air due to its greater density moves downward, and the cycle continues, this upward and downward movement is called convection current.
A lyric poem is usually short and expresses the personal emotions or feelings of the narrator. It is very rythmic, and the most common meters used in lyric poetry are iambic, trochaic, pyrrhic and anapestic. However, some lyric poems have a combination of more than one meter.
Lift Every Voice and Sing, by James Weldon Johnson, is a relatively short poem consisting of only 3 stanzas of 10, 11 and 12 lines respectively. The poem uses more than one meter, with the use of iambic meter for some lines. For example: "<em>Yet </em><em>with</em><em> a </em><em>stead</em><em>y </em><em>beat</em><em>, Have </em><em>not</em><em> our </em><em>wear</em><em>y </em><em>feet</em>"<em>.</em> There is also a lot of rhyming and repetition of patterns throughout the lines, and it deals with vivid imagery to express the emotions of the narrator. All of those elements are characteristic of a lyric poem.
