Summative assessment is used as an evaluation technique in instructional design. It can provide information on an intervention's efficacy (its ability to do what it was designed to do). Summative evaluation judges the worth, or value, of an intervention at its conclusion.
An international team of scientists has set a new record for the deepest known ocean fish. They were filming in the Mariana Trench â the deepest part of the ocean. The deepest part of the ocean is in the Mariana Trench (sometimes called the Marianas Trench), located in the western Pacific Ocean. At its deepest part, itâs just under 7 miles (6.831 miles / 10.994 km / 10,994 meters) deep.
The deepest point in the ocean is, not surprisingly, in the Mariana Trench. It is called the Challenger Deep, after the British ship Challenger II, which discovered this point in 1951 while surveying. The Challenger Deep lies along the southern end of the Mariana Trench near the Mariana Islands.he trench is 1,554 miles long and 44 miles wide, and is like the Grand Canyon of the ocean, although it is 120 times larger. Contrary to what you might picture, the trench is wide-according to NOAA, almost 5 times wider than it is deep. The Mariana Trench is located in the western North Pacific Ocean.
