The Chesapeake Bay impact crater is a buried impact crater, located beneath the mouth of Chesapeake Bay, United States. It was formed by a bolide that struck the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch. It is one of the best-preserved "wet-target" impact craters in the world. [3]
The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
There are three major routes to the Eastern Shore: The Chesapeake Bay Bridge spans 4.35 miles (7.00 km) of the Chesapeake Bay, and at the time of construction in 1952, was the longest continuous over-water steel structure. [24] A second parallel span was added in 1973 and a third has been discussed, most recently in 2006.
The Chesapeake Bay Bridge–Tunnel, connecting Virginia's Eastern Shore with its mainland (at the metropolitan areas of Virginia Beach, Norfolk, Portsmouth, and Chesapeake), is approximately 20 miles (32 km) long; it has trestle bridges as well as two stretches of two-mile-long (3.2 km) tunnels that allow unimpeded shipping; the bridge is ...
The thermosphere is the second-highest layer of Earth's atmosphere. It extends from the mesopause (which separates it from the mesosphere) at an altitude of about 80 km (50 mi; 260,000 ft) up to the thermopause at an altitude range of 500–1000 km (310–620 mi
Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force, as space scientists call it. But at 300,000 feet (91,440 m) or 57 miles up, this relationship ...
The Eastern Bay is a tributary of the Chesapeake Bay located between Queen Anne's County, Maryland and Talbot County, Maryland on the Eastern Shore. Its main tributaries include the Miles River and the Wye River. It is located south of the Chester River and north of the Choptank River and is connected to the Chester River via Kent Narrows.
The 17.6-mile-long (28.3 km) Chesapeake Bay Bridge–Tunnel, which is part of U.S. Route 13, spans the mouth of the Bay and connects the Eastern Shore to South Hampton Roads and the rest of Virginia. Before the Chesapeake Bay Bridge–Tunnel was built in 1964, the Little Creek-Cape Charles Ferry provided the continuation of U.S. 13 across this ...
