Notes:
‘Ecology is defined as the scientific study of the relationship of living organisms with each other and with their environment.’ It has been derived from two Greek words, ‘oikos’, meaning home or estate and ‘logos’ meaning study. Ecology not only deals with the study of the relationship of individual organisms with their environment, but also with the study of populations, communities, ecosystems, biomes, and biosphere as a whole.

Notes:
Asteroids also called the inner solar system are minor planets which are neither categorised as a planet or a comet. They are in direct orbit around the Sun. They primarily remain on the circumstellar disk of gas around new stars and also the debris of the disk together. They are also known as planetoids and range in size from hundreds of miles to few feet. Most of them are irregular in shape.  They are majorly present in the asteroid belt between Mars and Jupiter.

Notes:
The Gulf Stream is a warm current. It along with the northern extension the North Atlantic Drift and swift Atlantic Ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida and eastern coastlines of the United States and Newfoundland.

Notes:

Notes:
China is the world’s leading producer of synthetic industrial diamonds. Industrial diamonds can be used in cutting, drilling, grinding, and polishing.

Notes:
The Afsluitdijk in the Netherlands holds the title for the world’s longest seawall. Finishing construction in 1932, it spans approximately 32 kilometers (20 miles) across the IJsselmeer, a former saltwater inlet. This formidable dam does not merely serve as a shield against floods, but also carries out land reclamation and facilitates the formation of freshwater lakes. Remarkably, this seawall also plays a crucial roadway role, as it interlinks the northern provinces of North Holland and Friesland.

Notes:
Earth’s atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, ionosphere and exosphere.

Notes:
Pluto is usually farthest from the Sun. However, its orbit “crosses” inside of Neptune’s orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune’s orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.

Notes:
• Aleutian Islands are chain of small islands that separate the Bering Sea (north) from the main portion of the Pacific Ocean (south). They extend in an arc southwest, then northwest, for about 1,100 miles (1,800 km) from the tip of the Alaska Peninsula to Attu Island, Alaska, U.S.
• Kermadec Islands are volcanic island group in the South Pacific Ocean, 600 mi (1,000 km) northeast of Auckland, New Zealand; they are a dependency of New Zealand.
