Use the text to compare and contrast black tea and green tea
Green tea is known for its bright green color and mild flavor. Black tea is dark brown, with a stronger, deeper flavor. It surprises many people to discover that both of these teas are made from the leaves of the same plant. The leaves are simply processed in different ways. Green tea leaves are heated shortly after harvesting to preserve their fresh green color and flavor. Black tea leaves, on the other hand, are torn or rolled after harvesting and then exposed to oxygen before they are dried. This process changes the color and flavor of the leaves.
