Houston is a flat marshy area where an extensive drainage system has been built. The adjoining prairie land drains into the city which is prone to flooding.[64] Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.[65][66]
Few people realize that the Sabbath vs. Sunday controversy raged during the first three centuries of the Christian era, and thousands were tortured and put to death over this question both before and after the Emperor Constantine supposedly "resolved" the heated debate in his Sabbatical edict in AD 321. If so many chose death over observing a day not commanded by God, could not this dispute be more significant than we may have thought?
The holy day of rest and reflection observed each Saturday among the Jews. This custom fulfills the fourth of the Ten Commandments (“Remember the Sabbath day, to keep it holy”). The Sabbath commemorates the last of the seven days of Creation as described in the Book of Genesis, the day God rested from his labors of creating the heavens and the Earth.
The Houston area encompasses more than 300 private schools,[238][239][240] many of which are accredited by Texas Private School Accreditation Commission recognized agencies. The Houston Area independent schools offer education from a variety of different religious as well as secular viewpoints.[241] The Houston area Catholic schools are operated by the Archdiocese of Galveston-Houston.
The subbotnik is a weekly day of volunteer work on Saturday in Russia, other (former) Soviet republics, the Eastern Bloc, and the German Democratic Republic, sporadically observed since 1919. The voskresnik is a related volunteer workday on Sunday. They focus on community service work; "Lenin's Subbotnik" was also observed annually around his birthday.
METRO's local bus network services approximately 275,000 riders daily with a fleet of over 1,200 buses.[271] The agency's 75 local routes contain nearly 8,900 stops and saw nearly 67 million boardings during the 2016 fiscal year.[271] A park and ride system provides commuter bus service from 34 transit centers scattered throughout the region's suburban areas; these express buses operate independently of the local bus network and utilize the region's extensive system of HOV lanes.[272] Downtown and the Texas Medical Center have the highest rates of transit use in the region, largely due to the park and ride system, with nearly 60% of commuters in each district utilizing public transit to get to work.[272]
The arrival of the 20th century saw a convergence of economic factors which fueled rapid growth in Houston, including a burgeoning port and railroad industry, the decline of Galveston as Texas' primary port following a devastating 1900 hurricane, the subsequent construction of the Houston Ship Channel, and the Texas oil boom.[12] In the mid-20th century, Houston's economy diversified as it became home to the Texas Medical Center—the world's largest concentration of healthcare and research institutions—and NASA's Johnson Space Center, where the Mission Control Center is located.
The world church is governed by a General Conference, with smaller regions administered by divisions, union conferences, and local conferences. It currently has a worldwide baptized membership of over 20 million people, and 25 million adherents.[9][10] As of May 2007, it was the twelfth-largest religious body in the world,[11] and the sixth-largest highly international religious body.[12] It is ethnically and culturally diverse, and maintains a missionary presence in over 215 countries and territories.[2][13] The church operates over 7,500 schools including over 100 post-secondary institutions, numerous hospitals, and publishing houses worldwide, as well as a humanitarian aid organization known as the Adventist Development and Relief Agency (ADRA).
