Read the first stanza of "The Tide Rises, The Tide Falls."

The tide rises, the tide falls,
The twilight darkens, the curlew calls;
Along the sea-sands damp and brown
The traveller hastens toward the town,
And the tide rises, the tide falls.

Why does the poet most likely use the words “damp and brown” to describe the sands?
to create a subdued mood within the poem
to make the poem more haunting or unsettling
to give a sense of the time of year
to evoke sadness within the reader
