Notes:
Moraine is the name for raw glacial debris. They are the rocks that are loosened and carried by glacial ice, then deposited where the ice melts. So Moraine is a type of glacial deposit.

Notes:
The temperate grasslands of North America are known as the Prairies (Fig. 9.1). It is a region of flat, gently sloping or hilly land. For the most part, prairies are treeless but, near the low lying plains, flanking river valleys, woodlands can be found. Tall grass, upto two metres high, dominates, the landscape. It is actually a “sea of grass

Notes:
The pine trees grow in the coniferous forests. It is a cold climate which led to sharp leaves of the pine.

Notes:
Earth’s magnetosphere is a region of space surrounding our planet where the behavior of charged particles is largely influenced by Earth’s magnetic field. It extends far beyond the ionosphere, which is a region of the Earth’s atmosphere located from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth’s surface. The magnetosphere extends into space and interacts with the solar wind, a stream of charged particles emitted by the Sun, well beyond the boundaries of the ionosphere. The boundary of the magnetosphere, known as the magnetopause, can vary in distance from Earth depending on the strength and direction of the solar wind, but it typically extends tens of thousands of kilometers into space.

Notes:
The Red Sea Coral Reef is located off the coast of Egypt, Israel, and Saudi Arabia. It includes the Dahab Blue Hole, considered to be one of the most dangerous dive sites in the world.

Notes:
Spectroscope is used to measure the chemical composition of the stars. It is also used to measure the temperature and direction of the star moving in relation to the Earth.

Notes:
One of the greatest scientist of his times, Christiaan Huygens is known for his study of the rings of saturn and the discovery of its largest moon – Titan.

Notes:
The Mesozoic era lasted from 250 million years ago to 65 million years ago. It is divided into three periods – Triassic, Jurassic and Cretaceous.

Notes:
The average thickness of the continental crust is around 35 km. It is thicker than the oceanic crust.
