The majority of scientists agree that a single wave of people arrived in Alaska from Siberia around 13,000 years ago across a long-gone land bridge.
What became of the land link connecting Siberia and Alaska?
At its greatest length, the land bridge was nearly 1,000 miles long from north to south. When the glaciers melted at the end of the Ice Age due to climate change, Beringia was flooded approximately 10,000–11,000 years ago, severing the land bridge. By 6,000 years ago, coastlines were roughly where they are now.
When did the geographical connection between Alaska and Siberia vanish?
Around 13,000 years ago, the last ice age ended and the land bridge started to submerge into the water. As the massive continental ice sheets melted and released billions of gallons of fresh water, global sea levels surged.

Peterborough and Ottawa are 270km apart. The scale on the map shows 1cm to 100km. How many centimeters apart would these to cities be on a map?
Based on the distance between Peterborough and Ottawa, the distance in centimeters between the cities on a map would be 2.7 cm.
How to find the distance on a map?To find the distance on a map, you need to know the scale of the distance between two areas on that map.
A scale of 1 cm to 100 km means that every centimeter on the map is equivalent to 100 km on the ground.
If Peterborough and Ottawa are 270 km apart from each other, then their distance on the map is:
= 270 km / 100 km per centimeter
= 2.7 cm

How does the rate of erosion vary with PH?
PH has a profound effect on the rate of erosion. Acidic conditions with a pH of about 2 gradually develop as a result of acid mine drainage, which frequently happens at the waste dumps of mining sites.
Does pH affect erosion?At mine sites, where mining operations lead to pH variations, the pH conditions can alter the risk of soil water erosion through changes in the physical features of soils.
What affects the rate of soil erosion?Numerous variables, such as the nature of the soil, the vegetation present, and the force of the wind and rain all affect the rate of soil erosion. We have the ability (and the duty) to address one of the biggest environmental issues facing the planet since our own actions can also affect how quickly soil erosion occurs. The amount of substances that are soluble in soil water and, consequently, the amount of nutrients that are made available to plants, depends on the pH of the soil. Some nutrients are more easily absorbed when the environment is acidic, whereas others are better absorbed when the environment is alkaline.

Identify and Describe the crust (earth)
Short answer please
Answer:
The outermost layer of a terrestrial planet is referred to as its "crust." All known life in the universe is contained in the thin, 40 kilometer (25 mile) deep crust of our planet, which makes up just 1% of Earth's mass. The crust, mantle, and core are the three layers that make up the earth. Minerals and solid rocks make up the crust. The mantle, which lies below the crust, is composed primarily of solid rocks and minerals with some pliable regions of semi-solid magma. There is a heated, dense metal core in the center of the Earth.
what are the two major tectonic plates
Answer: oceanic and continental
Explanation: . Oceanic - Oceanic plates consist of an oceanic crust called "sima". Sima is made up primarily of silicon and magnesium (which is where it gets its name). Continental - Continental plates consist of a continental crust called "sial".

C. In 1–2 sentences, analyze one specific program in the context of the principles and guidelines you explained in Part B
Frank Notestein devised the Demographic Transition Theory (DTT) in 1945. The age distribution and population growth rate effects of birth and death rates are explained by this theory.
Death rates are low and birth rates are declining in Stage 3 of the Demographic Transition Model (DTM), typically as a result of better economic conditions, rising levels of women's status and education, and increased access to contraception. Botswana, Colombia, India, Jamaica, Kenya, Mexico, South Africa, and the United Arab Emirates are a few examples of Stage 3 nations.
Birth and death rates are both low in Stage 4 of the Demographic Transition Model (DTM), stabilizing total population growth. Most Stage 4 nations' declining birth and mortality rates have been linked to their robust economies, highly educated populaces, comprehensive healthcare systems, population shift from rural to urban areas, and increased employment options for women. Argentina, Australia, Canada, China, Brazil, the majority of Europe, Singapore, South Korea, and the United States are a few examples of nations in Stage 4 of the Demographic Transition.
