danny and his sister minnie decided to go tubing over the summer break in a nearby river. when they arrived they saw a location where someone had dumped some household trash into the river. how does dumping waste into rivers pose a threat to the ocean?
a) rivers have no connection to oceans so there is no threat.
b) rivers flow into oceans and will carry the waste with them.
c) animals in the river will move to the ocean to escape the waste.
d) the same people who dump waste in rivers will also place waste in the ocean.

B

Explanation:

Rivers flow to the ocean because most water forms connect, the exceptions are bodies of water like lakes and bays, so it can't be A. Animals in a river are always moving and by the animals moving to the ocean it won't threaten the ocean. Just because people dump waste in a river doesn't mean that they will dump it in the ocean, that is just an inference, so its not d.

Most bodies of water are connected so the rivers will carry the waste into the ocean so the answer is B

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
