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.
Answer: The ocean's deepest area is the Mariana Trench (also called the Marianas Trench), which is about 11 km (almost 7 miles, or almost 36,000 feet) deep. The 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.he 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.
