Environmental science is an expression encompassing the wide range of scientific disciplines that need to be brought together to understand and manage the natural environment and the many interactions among physical, chemical, and biological components. Environmental Science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.Individuals may operate as Environmental scientists or a group of scientists may work together pooling their individual skills. The most common model for the delivery of Environmental science is through the work of an individual scientist or small team drawing on the peer-reviewed, published work of many other scientists throughout the world

A motorcycle (also called a motorbicycle, motorbike, bike, or cycle) is a single-tracktwo- wheeled motor vehicle powered by an engine. Motorcycles vary considerably depending on the task for which they are designed, such as long distance travel, navigating congested urban traffic, cruising, sport and racing, or off-road conditions. In many parts of the world, motorcycles are among the least expensive and most widespread forms of motorised .

The Indus River (Sanskrit: सिन्धु Sindhu; Urdu: سندھ Sindh; Sindhi: سندھو Sindhu; Punjabi سندھ Sindh; Avestan: حندو Hindu; Pashto: ّآباسن Abasin "Father of Rivers"; Persian: Nilou "Indigo Waters"; Tibetan: Sengge Chu "Lion River"; Chinese: 印度河 Yìndù Hé; Greek: Ινδός Indos) is the longest river in Pakistan and the twenty-first largest river in the world in terms of annual flow. It is often considered the life-line of Pakistan by the people of that country. The Europeans used the name "India" for the entire Indian Subcontinent based on Indos, the Greek appellation of this river. Originating in the Tibetan plateau in the vicinity of Lake Mansarovar, the river runs a course through Ladakh district of the state of Jammu and Kashmir in India and the Northern Areas (Gilgit-Baltistan), flowing through the North in a southerly direction along the entire length of the country, to merge into the Arabian Sea near Pakistan's port city of Karachi. The total length of the river is 3,180 kilometres (1,976 miles). The river has a total drainage area exceeding 1,165,000 square kilometres (450,000 square miles). The river's estimated annual flow stands at around 207 cubic kilometres. Beginning at the heights of the world with glaciers, the river feeds the ecosystem of temperate forests, plains and arid countryside. Together with the rivers Chenab, Ravi, Sutlej, Jhelum, Beas and the extinct Sarasvati River, the Indus forms the Sapta Sindhu (Seven Rivers) delta in the Sindh province of Pakistan.

K2 is the second-highest mountain on Earth (after Mount Everest). With a peak elevation of 8,611 meters (28,251 ft), K2 is part of the Karakoram segment of the Himalayan range, and is located on the border[ between Pakistan's northern territories, and the Tax organ Tajik Autonomous County of Xinjiang, China. K2 is known as the Savage Mountain due to the difficulty of ascent and the fact that for every four people who reach the summit, one dies trying. Among the eight-thousanders, K2 has the third highest climbing mortality rate.

Baltistan (Urdu: بلتستان, Hindi: बल्तिस्तान) , also known as بلتیول (Baltiyul) in the Balti language, is a region in northern Pakistan (administratively situated in Northern Areas. Northern Areas were part of Jammu and Kashmir and came under Pakistani control in 1947) , bordering Xinjiang Autonomous Region of China. It is situated in the Karakoram mountains just to the south of K2, the world's second highest mountain. It is an extremely mountainous region, with an average altitude of over 3,350 m (11,000 ft). It is inhabited principally by Balti Shi'a Muslims of Tibetan descent who converted from Tibetan Buddhism prior to the 16th century.
Baltistan was an independent state but was occupied by the Raja (King) of Kashmir in the nineteenth century. In 1947 when India and Pakistan gained independence, it was still part of Kashmir. Now the region is divided between Pakistan and India. The districts of Skardu (Skardo) and Ganche, which is a part of the Northern Areas of Pakistan, its main town is Skardu. It contains the highest peaks of the Karakoram, including K2. Indian-controlled Baltistan (the district of Kargil) which is disputed and claimed by Pakistan is located in the north of Indian-administered Kashmir.

Computer science (or computing science) is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that describe and transform information; the fundamental question underlying computer science is, "What can be (efficiently) automated?" Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing computations, while computer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to people.
The general public sometimes confuses computer science with vocational areas that deal with computers (such as information technology), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones.
