The 40th parallel north is a circle of latitude that is 40 degrees north of the Earth's equatorial plane. It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean . At this latitude the sun is visible for 15 hours, 1 minute and 28 seconds during the summer solstice and 9 hours, 20 minutes during ...
The geographical mile is defined as one arc-minute of the Equator, so it has different values depending on which radius is assumed. For example, by WSG-84, the distance is 1,855.3248 metres (6,087.024 ft), while by IAU-2000, it is 1,855.3257 metres (6,087.027 ft).
San Antonio (/ ˌ s æ n æ n ˈ t oʊ n i oʊ / SAN an-TOH-nee-oh; Spanish for "Saint Anthony"), officially the City of San Antonio, is a city in the U.S. state of Texas and the most populous city in Greater San Antonio, the third-largest metropolitan area in Texas and the 24th-largest metropolitan area in the United States at 2.6 million people in the 2020 US census.

The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans ), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes ), all retained by Earth's gravity.
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The predicted values for the moment of inertia based on planetary models suggest a core radius of 2,900–3,450 km. [74] This is in line with the first observation-based estimate of 3,500 km. [76] The principal difference between the two planets is the lack of evidence for plate tectonics on Venus, possibly because its crust is too strong to ...
As one degree is 1 / 360 of a circle, one minute of arc is 1 / 21600 of a circle – such that the polar circumference of the Earth would be exactly 21,600 miles. Gunter used Snellius's circumference to define a nautical mile as 6,080 feet, the length of one minute of arc at 48 degrees latitude. [24]
The most recent storm that moved onshore in the Northwest on Wednesday has already dropped well over a foot of snow in portions of the Washington Cascades. At least 29 inches had fallen at Stevens ...
