Answers

Answer:

Answers are given below.

Explanation:

1. The reasons for people moved in ancient times was to find the source of foods. The people were nomadic, due to climatic conditions,  natural disaster, hunting, search for water and food, led them to move from one place to another.

2. The migration mostly lead the population to grow and spread in different parts of the world. According to anthropologist, humans (Homo sapiens) evolved in Africa and spread to the rest of the world through migration.

3. During the Paleolithic Age, humans were hunters and gatherers. For food, they were travelling and moving from one place to another. Food gathered and collected, including wild plants, berries, roots, etc., and pursuing wild animals. Eating fruit and berries as they ripened.

The Paleolithic caves play a vital role in helping humans by providing shelters from weather, wild animals. Fire use for the first time. They use animal skin, stone, woods, and bones for making tools and other material. They had tools like spears and others made out of stone.

4. In a permanent settlement, people have to settle in one place without worrying about constantly moving to different places. Agriculture was the main occupation of the people. All this led to forming community or villages where humans lived a large group.

In nomadic life, humans have to search for food. They don't have any permanent place to stay as they are in constant movement. They followed herds of large mammals for food and water.

What is common law?

In law, common law is the body of law created by judges and similar quasi-judicial tribunals under being stated in written opinions.

The defining characteristic of common law is that it arises as a precedent. Common law courts look to the past decisions of courts to synthesize the legal principles of past cases. Stare decisis, the principle that cases should be decided according to consistent principled rules so that similar facts will yield similar results lies at the heart of all common law systems. If a court finds that a similar dispute as the present one has been resolved in the past, the court is generally bound to follow the reasoning used in the prior decision.

The term "common law", referring to the body of law made by the judiciary, is often distinguished from statutory law and regulations.

What life was like for a crusaders?

Answer:

Jesus is always the answer can i have brainlest now

Explanation:

Answer:

Like any great conflict, the Crusades have been the subject of myths and misinformation for years. While few still believe the propaganda that justified the fighting, various false facts have proliferated over the years, concerning everything from the motivations of the Crusaders to their reception in Arab lands. It's easy to understand how both storytellers and audiences get swept up in the romance of the Crusades. The epic sweep, the clash of cultures, and the stunning aggression still thrill us today. But what was life actually like for a medieval crusader? Of course, the answer varies. The wars were radically different experiences for a noble knight than they would be for a common farmer. A day in the life of a Crusader, like soldiers throughout history, alternated between boring and terrifying, exhilarating and tragic. But in the midst of the conflicts, the Crusaders also met a new culture, forged new trade routes, and shifted the social and political landscape.

The Himalayan Mountains, which are some of the highest in the world separate India and China. What can you conclude about how the two
civilizations developed

Answers

Answer:

The cultures developed separately because they found it difficult to cross the Himalayan Mountains to invade or trade with each other.

Explanation:

The Himalayan mountain ranges divide India and China. Because each nation had a unique history, the two civilizations evolved independently.

Since many centuries ago, many lineages have ruled the two nations. Thus, despite the fact that they are neighboring nations, their cultures, religions, lifestyles, and clothes are very distinct from one another.

What is the Himalayan Mountain range?

The Himalayas, also known as the Himalayas, is a mountain range in Asia that divides the Tibetan Plateau from the plains of the Indian subcontinent. The mountain range has some of the world's tallest peaks, including Mount Everest, which is the highest.

The Himalayas border or traverse five nations: China, Pakistan, India, Nepal, and Bhutan. The Karakoram and Hindu Kush mountains border the Himalayan range on the northwest, the Tibetan Plateau on the north, and the Indo-Gangetic Plain on the south. Several of the world's largest rivers, including the Ganges, the Tsangpo-Brahmaputra, and the Indus.

The Himalayas are divided into three groups: the Greater Himalayas, the Lesser or middle Himalayas, and the Shiwalik or the outer Himalayas.

What are the causes and effects of overgrazing?

Answers

Answer:

overgrazing

Explanation:

Herds have to be driven from place to place to find food and water. Generally, cattle fed valleys and open range while sheep feed higher in mountains, causing over grazing at all altitude levels. As mature grasses become scarce, cattle and sheep eat new grass before it produces seed. Hooves of both animals destroy root systems and their trampling hardens the soil so grass seedlings could not survive. Water holes became large mud holes where no grasses grew and the land could no longer capture and store water. Grassland was replaced by scrub grass and sagebrush. With grasses gone, the range climate becomes hot and arid.

Overgrazing occurs when livestock or other grazing animals consume vegetation in an area at a rate exceeding its natural regeneration capacity.

The causes of overgrazing can include inadequate pasture management, overstocking of animals, and limited grazing options. The effects of overgrazing are manifold. It leads to the depletion of vegetation, soil erosion, reduced soil fertility, and loss of biodiversity.

With less vegetation cover, the land becomes more susceptible to desertification and degradation. Overgrazing also disrupts the natural balance of ecosystems, impacting wildlife habitats and reducing water infiltration.

Ultimately, overgrazing can result in the degradation and degradation of rangelands, posing long-term challenges for both the environment and livelihoods dependent on grazing systems.
