The Zarqa River (Arabic: نهر الزرقاء) is the second largest tributary of the lower Jordan River, after the Yarmouk River. It is the third largest river in the region by annual discharge, and its watershed encompasses the most densely populated areas east of the Jordan River. It rises in springs near Amman, and flows through a deep and broad valley (which is identified with the biblical Jabbok River) into the Jordan, at an elevation 1,090 meters (3,580 ft) lower. The river is heavily polluted and its restoration is one of the top priorities for the Jordanian Ministry of the Environment.
Geologically, the Zarqa river is about 30 million years old. At the river's origin is 'Ain Ghazal, a major archaeological site that dates back to the Neolithic period. Archeological finds along the course of the river indicate the area was rich in flora and fauna in the past. The Zarqa river is well known for its amber deposits that date back to the Hauterivian of the lower Cretaceous (135 m.y.). A remarkable flora and fauna was reported from this amber reflecting a tropical paleoenvironmental prevailing conditions during the time of resin deposition (Kaddumi, 2005; 2007).
Az-Zarqā (Arabic: الزرقاء; BGN: Az Zarqāʼ; local pronunciation ez-Zergā, ez-Zer'a, or ez-Zarka) is a city in Jordan located to the northeast of Amman. Zarqa is the capital of Zarqa Governorate. Its name means "the blue one".
Zarqa is located in the Zarqa River basin in northeast Jordan.
It is situated 15 miles (24 km) from Amman, in a northeastern direction.
Although inhabited since the 1st century, the city of Zarqa was established by immigrants from the Caspian Sea region at the beginning of the 20th century. The first settlement in the city was established in 1902 by Chechen immigrants who were displaced from the wars between the Ottoman and Russian Empires. They settled along the Zarqa River. At that time a station on the Hejaz Railway was built in the new settlement. The railway station turned Zarqa into an important hub. On 10 April 1905, the Ottoman governor issued a decree that allowed the Chechen immigrants to own lands which they settled on. The population then quickly grew in size. On 18 November 1928, the new Jordanian government issued a decree to establish the first municipal council for Zarqa.
Zarka or zarqa (Hebrew: זַרְקָא֮, with variant English spellings) is a cantillation mark found in the Torah, Haftarah, and other books of the Hebrew Bible. It is usually found together with the Segol, with a Munach preceding either or both. The symbol for a Zarka is a 90 degrees rotated, inverted S. The Hebrew word זַרְקָא֮ translates into English as scatterer, since it is a scattering of notes.
Zarka is part of the Segol group. In this group, Zarka is the connector and Segol is the separator.
Zarka is also sometimes called tsinnor. Properly speaking, tsinnor is the name it receives when appears on the three poetic books (Job, Proverbs and Psalms, or the א״מת books, from their initials in Hebrew), and zarqa the name it gets on the remaining 21 books of the Hebrew Bible (also known as the prosaic books). Both sets of books use a different cantillation system.
Caution must be take not to confuse this mark with the very similar mark tsinnorit, which has the same shape but different position and use. They differ in the following:
