World & Physical Geography MCQs

Notes:
River Jordan drains into the Dead Sea. The Jordan River flows through the Middle East and forms part of the border between Israel and Jordan. It ultimately empties into the Dead Sea, which is a landlocked saltwater lake known for its high salinity and unique geological features.

Notes:
The precession of the Earth’s axis has a number of observable effects. First, the positions of the south and north celestial poles appear to move in circles against the space-fixed backdrop of stars, completing one circuit in 25,772 Julian years (2000 rate). Thus, while today the star Polaris lies approximately at the north celestial pole, this will change over time, and other stars will become the “north star”

Notes:
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. Sedimentary rocks are formed inside the earth under great pressure.

Notes:
International Date Line runs from the North Pole to the South Pole across the Pacific Ocean, roughly following the 180° line of longitude. It demarcates the change of one calendar day to the next. The time difference on either side of the International Date Line is 24 hours.

Notes:
The timing of high tides is influenced by the gravitational pull of the moon and the sun on Earth’s oceans, as well as the geographical location of the place in question. High tides typically occur approximately 12 hours and 25 minutes apart, but this can vary based on local geography and the specific tidal cycle.
If a high tide occurs at a particular place at 8:00 AM, you can generally expect the next high tide to occur roughly 12 hours and 25 minutes later. Therefore, you can expect the next high tide around 8:25 PM on the same day.

Notes:
Neptune has five rings: Galle, LeVerrier, Lassell, Arago, and Adams. Its rings were named after the astronomers who made an important discovery regarding the planet.

Notes:
Siderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word ‘sideros’, “iron”. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.

Notes:
Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. Mount St. Helens is 34 miles (55 km) west of Mount Adams, in the western part of the Cascade Range. These “sister and brother” volcanic mountains are approximately 50 miles (80 km) from Mount Rainier, the highest of Cascade volcanoes.

Notes:
The C layer lies immediately above the R layer (bottom most layer). It consists of broken rock fragments and it is devoid of any organic content. C layer is also called as Saprolite.

Notes:
The Isthmus of Korea is located between the Sea of Japan and the Yellow Sea. It is an area of Korean Peninsula, which narrows to 160 km. It lies between the Korea Bay and the East Korea Bay.
