(science)
a ship leaves a saltwater port, heavily loaded with cargo. it sails across the ocean, but when it arrives at its destination, it has to dock at a port located in the mouth of a river. as it approaches this port, it starts to sink lower in the water. the cargo has not shifted or changed in any way. why is the ship floating lower in the water?

The fresh water in the river is slightly less dense than the ocean's brine. So in order to displace its weight of water, the ship must displace more of it. That means it sinks slightly lower in fresh water before the displaced water totals up to the ship's weight.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
