The correct answer is D) iron and wood.

The raw materials that had to be shipped to the construction sites in large quantities because they were essential for building the railroad tracks were iron and wood.

The Pacific Railroad Act of 1862 allowed the construction of a transcontinental railroad to connect the East coast of the United States with the West coast. The Union Pacific Railroad and the Central Pacific were the two companies that could receive the task to accomplish this important feat. They worked for seven years to connect the railroads from Omaha, Nebraska to Sacramento, California, until they finally met on May 10, 1869, in Promontory Utah.

which of these developments was caused in part by the end of the last ice age and its resulting climate change around 9000 bce?
svet-max [94.6K]

Answer:

a) The rise of farming and domestication of animals.

Explanation:

An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet.

What caused the end of the Ice Age?

The variation of sunlight reaching Earth is one cause of ice ages. ... When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

Developments caused in part by the end of the last ice age and its resulting climate change around 9000BCE:

Around 10,000 years ago, the latest ice age came to an end. Sea levels rose as the ice sheets melted, and Britain became separated from the European mainland shortly

The introduction of farming, when people learned how to produce rather than acquire their food, is widely regarded as one of the biggest changes in human history.

This change happened at various times in several different places around the world. The concept of farming that reached Britain between about 5000 BC and 4500 BC had spread across Europe from origins in Syria and Iraq between about 11000 BC and 9000 BC.

Traditionally the arrival of farming is seen as a major and rapid change sometimes called the 'Neolithic revolution'
