there has been multiple ice ages on earth. what causes ice ages?

Answers

Answer 1
The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.
Answer 2

Answer:

The variation of sunlight reaching Earth is one cause of ice ages. .

Explanation:

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.

When people from one location move or transferred to another location in search of livelihood and seek better opportunities for the future to have financial stability in life along with security is considered migration.

Economical reasons, such as a lack of employment and economic opportunity, motivate people to leave their homes and relocate elsewhere, whereas pull factors draw migrants to new locations for bringing positive change in their lifestyle.

In relation to the structure and size of the sun how are the following achieved absorption , reflection,transmission,scattering and diffusion

Answers

Answer:

Explanation:

Scattering of solar radiation within the atmosphere also accounts for a reduction of energy reaching Earth. Atmospheric gas molecules and aerosols deflect solar radiation from its original path, scattering (reflecting) some radiation back into deep space and some toward Earth's surface.

Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

A Quick Overview of Light Absorption

In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.

The U.S. Federal Reserve says problems with the supply chain are threatening to
lengthen the rise in prices of goods and services, which is known by what one-word
term?

Answers

Answer:

Inflation

Explanation:

A supply chain, in the most basic form, is the set of actions necessary by an organization by providing goods or services to customers.

A supply chain is a focus on the main processes necessary to turn raw materials or component components into completed products or services inside our company.

The correct word for the rise in the prices of goods and services is inflation.

This is the correct answer because inflation is measured as the rate at which prices go up over time. Inflation is usually defined as little more than a wide measure of price increases or a rise in the cost of living in a nation.

In economics, inflation is defined as a gradual increase in the price of goods and services in a given economy. When the overall price level rises, each unit of currency buys fewer products and services; as a conclusion, hyperinflation equals a loss of money's buying power.

Which layer of earth is liquid

Answers

Answer:

The Outer Core & Inner Mantle

Explanation:

The crust and the inner core are solid, whereas the outer core and inner mantle are liquid. The outer mantle is semi solid. The inner core is solid due to the massive pressure on it. Scientists theorize that the heat of the solid inner core is keeping the outer core in a semi-liquid state which allows the inner core to spin at a slightly different rate than the rest of the earth. This gives the earth its magnetic poles which diverts damaging cosmic rays from colliding with earth. The theories are the result of measurements during volcanic activity and sound waves. The mantle is a plastic solid of varying densities which allow convection currents to flow molten rock towards the earth's surface resulting in volcanic activity, tectonic plate movement, earthquakes, and movement of continents.

Explanation:

China is the number one producer of gold in the world. The USGS estimates that China mined 455 metric tons of gold in 2016. Since gold began to be mined in the 1970s, gold production in China has rapidly increased.

[tex]Answer- [/tex]

China, Australia, Russia, and the United States are respectively the largest producers of gold in the world. Global production of gold reached approximately 3,200 metric tons in 2020. Production in China has increased from 320 metric tons in 2009 to an estimated 380 metric tons in 2020.

About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
