Question

which statement explains one way that lakes form?
○ lava flows block a river.
○ streams flow into shallow areas.
○ groundwater feeds into low - lying areas.
○ grassy wetlands get covered by a stream.

Explanation:

Lakes can form when lava flows block a river. This creates a natural dam, causing water to accumulate behind it and form a lake. Streams flowing into shallow areas typically form wetlands or marshes, not lakes. Groundwater feeding into low - lying areas usually forms springs or groundwater - fed wetlands. Grassy wetlands getting covered by a stream is more likely to create a marshy or swampy area rather than a lake.

Answer:

Lava flows block a river.
