Explanation:
The right answer to this question is A. a crest that is toppling over. When a surfer rides an ocean wave on her surfboard, she is actually riding on a crest. The crest is the point on a wave with the maximum value or upward displacement within a cycle.
The statement is false. Balanced forces can NOT change the speed OR direction of an object's motion. (See Newton's #1 law of motion.)
Answer: Option B
Explanation:
Rocks contains pores and spaces in them in which water gets trapped, and this causes the rock to break as water increases its volume due to freezing. This rocks are then eroded and are carried away into the streams and channels. The rivers and streams can carry particles of various shapes and size, which are further transported and deposited at a different place.
This particles or sediments then gets compacted and lithified in due course of time, and forms sedimentary rocks.
Water is also needed to undergo metasomatism process, that creates a metamorphic rock.
Hence, water flow is also an important driving force in rock cycle, along with tectonic activities.
Thus, the correct answer is option (B).
