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.Various measurements have been taken of the ocean's depth at the Challenger Deep, but it is usually described as about 11,000 meters deep, or close to 7 miles beneath the ocean's surface.he Mariana Trench is so deep because it is an area where two of the Earth's plates converge and one (the Pacific plate) is subducted, or dives underneath, the other (the Philippine plate). During this slow process, the Philippine plate also gets pulled down.
