Which evidence proves the universe began with the big bang?.

Answers

Answer 1

The universe started with the Big Bang, as indicated by the following pieces of evidence: cosmic microwave background radiation, the abundance of light elements, and the redshift of light from other galaxies.

What is the Big Bang theory?

The Big Bang is a scientific theory that describes the beginning of the universe. According to this theory, the universe began as a hot, dense, and infinitely small point known as a singularity. Then, nearly 14 billion years ago, it expanded rapidly, became cooler and less dense, and created all of the matter and energy that make up the universe.

This radiation is incredibly uniform and corresponds to a blackbody temperature of 2.7 K, which is evidence for the universe's expansion. The second piece of evidence supporting the Big Bang theory is the abundance of light elements, specifically hydrogen and helium.

The Big Bang model predicts that about 75% of the universe's mass should be hydrogen, with most of the remainder being helium. Observations of the universe indicate that this is indeed the case. There is an abundance of light elements in the universe, which is consistent with their creation during the Big Bang. The third piece of evidence supporting the Big Bang theory is the redshift of light from other galaxies.

The Big Bang model predicts that galaxies and other celestial objects should be moving away from us, and this is consistent with observations. Additionally, the farther away a galaxy is from us, the more its light is redshifted, which indicates that it is moving away from us more rapidly.

When looking at a map that accurately depicts the major rivers, mountainous regions, desert provinces, and population concentrations of a particular area, two prominent topographical patterns you might observe are plateaus and valleys.

What is a Plateau?

A plateau is typically characterized as an extensive landscape that is relatively level and elevated above its bordering areas. It generally finds itself alongside mountain ranges and can be marked on maps with its shallow, elevated surface area.

Valleys, however, are narrow and low-lying parts of the land between two higher points — such as mountain ranges — formed usually by running water. They can be spotted on maps by their lengthy, curved shape.

In geography, regions are parts of the Earth's surface that are roughly differentiated by physical features, human influence qualities, and the interaction of humans and the environment. Regions are sometimes known as areas, zones, lands, or territories.

A region is a piece of territory with similar characteristics. Natural or man-made elements might serve to identify a region. A region may be defined by its language, governance, or religion, as well as by its woods, wildlife, or climate. The basic units of geography are regions, no matter how big or tiny.

Ethnic groups around the world seek the ability to be the majority in control of countries, or to have more autonomy over their own affairs in their own state. Nationalism is loyalty and allegiance to a particular country, while ethnicity is a strong identity with a cultural group around some element of culture, such as language. Identify and describe three causes of ethnic conflict, and give an example of each.​

Answers

Answer:

Causes of ethnic conflict are intolerance between different ethnic groups, aspiring for independence, and suppression.

Explanation:

There have been ethnic conflicts around the world for thousands of years, there still are, and it seems that there will be many more in the future as well. The reasons are numerous for such conflicts and over time they have changed at least the primary ones. Nowadays, ethnic conflicts are mainly based on intolerance, wanting independence, and suppression.

Some ethnic groups simply don't seem to stand each other historically, and this intolerance often leads to violence and larger conflicts. An example of this is the conflict (with genocide) in the '90s in Rwanda between the Tutsis and Hutus.

Some ethnic groups feel as they have been occupied, that they don't share common values with the country under which government they are, and they want to be independent entities. This results in conflicts between the ethnic group that wants independence and the majority group that doesn't want to give up the territory. An example of this is the several conflicts between Chechnya and Russia.

Some ethnic groups are supressed by the majority groups so they want to be independent and have their rights instead of being deprived of them. This often can cause the bloodiest and longest conflicts. An example of this is the ongoing conflict between Turkey and the Kurds.

throughout time, continents break apart and collide and ocean basins open and close. this cyclical process is known as the .

Answers

The Wilson Cycle is a model that explains how ocean basins open and close as well as how tectonic plates subduct and diverge during the building and disassembly of supercontinents.

Continental drift is a phenomenon that caused the continents to separate. Alfred Wegener, who suggested that the Earth's continents were originally a single supercontinent, initially put out this hypothesis in 1912. As the continents separate, Pangaea continues to fragment. The Pacific Ocean is growing smaller while the Atlantic Ocean is expanding. Every 500 million years or so, the continents merge and separate. The cycle of supercontinents is what causes this. A continental mountain chain is created when the remainder of the sea bottom is destroyed and continents clash.

How are regions of the oceans defined by light availability?

Answers

Regions of the oceans can be defined by light availability in terms of their depth and the amount of light that can penetrate the water column.

Light is an essential factor for photosynthesis, which is the process by which primary producers such as phytoplankton and algae convert sunlight into organic matter.

These primary producers are the foundation of the oceanic food web, and they play a critical role in supporting the marine ecosystem.

In general, the ocean can be divided into three regions based on light availability:

The euphotic zone: This is the uppermost layer of the ocean where sunlight can penetrate and support photosynthesis.

The depth of the euphotic zone varies depending on water clarity, with clearer water allowing light to penetrate deeper.

what is the most common element in the earth's crust

Answers

The most common element in the Earth's crust is oxygen.

Oxygen is the most abundant element in the Earth's crust, comprising approximately 46.6% of its mass. The Earth's crust is primarily composed of a variety of minerals, and oxygen is a major component of many of these minerals. It is found in combination with other elements, forming oxides, silicates, carbonates, and other compounds. Silicon is the second most abundant element in the Earth's crust, making up around 27.7% of its mass.

The presence of oxygen in the Earth's crust is a result of geological processes such as weathering, erosion, and volcanic activity. Over millions of years, rocks are broken down, minerals are formed, and elements including oxygen are redistributed throughout the Earth's crust. The high abundance of oxygen in the crust is crucial for sustaining life on Earth, as it is a fundamental component of water and many organic compounds.

South America's and North America's west coasts are both active margins. Active continental edges often have abrupt descents into trenches and are narrow from coast to the shelf break. Where oceanic and continental plates collide, there are convergent active margins.

Central and southern California are active margins with transform zones, whereas the northwest coast of the Pacific Ocean in North America and the west coast of South America are active margins with subduction zones.
