Answer:
Photosynthesis was a major source of atmospheric oxygen.
Explanation:
Earth's atmosphere was not the same as it is in the past. For a larger portion of Earth's history, the atmosphere actually didn't have an atmosphere or the one it had was not suitable for complex lifeforms to develop. This all changed because of one major event, the process of photosynthesis.
Initially, it was the cyanobacteria that started to use this process in order to produce their own food and energy. Basically, this process meant that the cyanobacteria, and a lot of later organisms, were taking in carbon dioxide, use it for their own needs, and release the oxygen. The oxygen was released into the ocean and into the atmosphere, which resulted in a gradual change in the composition of the atmosphere to a degree where it was suitable for larger organisms to start to develop.

Heat Flow Inside Earth Activity
Answer:
1- Explosive situation
As it said in the lesson the tectonic plates allow magma to build up over time and then it goes up into the volcano when it finally goes up it explodes in a volcano
What you should say- Tectonic plates allowing magma to build up so our local volcanoes in mount tambora can explode?
2- Shake rattle and roll
Umm yeah... The lesson said it occurs when the tectonic plates collide pull apart or or slide pass each other creating the earthquake.
What you should say- Earthquake caused in the indian ocean because of our tectonic plates passing each other.
3- Ocean expansion
as it says in the lesson ocean expansion (or ocean basin) are caused when the tectonic plates and uplift the new rocky crust causing the ocean to form.
What you should say- Tectonic plates causing our oceans to form because of otectonic plates uplifing new rocky crust in the pacific!
4- island popping up everywhere (or as i like to call it island games)
it says in the lesson when rocks uplift from the bottom of the ocean it causes a island
What you should say- Tectonic plates uplifting rocks from the sea to create oceans in the Caribean?

The earth heat flow is 80% by mantel convection and 1% by volcanic activity.
What is heat flow of earth ?The heat flow of the earth is regulated by two factors such as the external that is sun and the internal factors such as geothermal heat.
Due to the volcanic activity of the earth the heat is released from the mantel of the earth in the form of lava. While 99% of the earth's heat is lost by the conduction by crust.
The movement of the heat from the earth's core to the mantle and then to the crust is caused by the convective current coming from below and this leads to the formation of volcanic activity, formation of mounting, and leads to earthquakes.

Why did the US and USSR never declare war on one another?
Answer:
Neither country wanted to engage in a nuclear war that would lead to
worldwide destruction.
Explanation:
The US and the USSR were the two global powers between the end of the World War II and the beginning of the 1990s. Each of them was the leader of a block, with the US being the leader of the democratic and capitalist world, while the USSR being the leader of the communist and command economy world.
Despite all of the tensions between the two, and often engaging in wars in other territories on opposite sides, they never engaged in a direct war with each other. They had everything they needed to do so, being heavily militarized and with an abundance of nuclear weapons, but luckily they didn't fight directly. The explantion for this is simple, they were aware that if they entered a war with each other they would destroy the whole world, so everyone would have lost and there wouldn't have been any gain from it.

What happens at a divergent boundary?
A. Two tectonic plates slide past each other.
B. One tectonic plate slides under another.
C. Two tectonic plates move away from each other.
D. Two tectonic plates move toward each other.
Two tectonic plates move away from each other at a divergent boundary. Thus, option C is correct.
What is the tectonic plates?A tectonic plate is also known as a lithospheric plate, is a substantial slab of solid rock with an uneven shape that is typically made up of both continental and oceanic lithosphere.
The Pacific and Antarctic Plates are among the largest plates, but they can range in size from a few hundred to thousands of kilometres broad. People can't survive underwater, therefore it created the continents on which we now reside.
Volcanoes are produced when plates clash and subduct (when one plate slides under another). Peoples believe that this procedure, repeated numerous times, is what created the continents.
Therefore, option C is correct, that the At a diverging border, two tectonic plates advance apart.

There are many different kinds of graphs, including connected and unconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs.
Because they make information accessible and simple to comprehend, graphs and charts are effective visual aides.

The fastest flow is on the inside of a meander bend. True or false
Answer:
True.
Explanation:
Because when the water flows faster it has more power to erode the outside bank. The outside bend of the meander becomes deeper, reducing friction and allowing for even faster flow of water, which in turn means more erosion. On the inside bend of the meander the river is flowing much slower.

what seafloor structures you would encounter if you could walk underwater from the United States to Europe
Answer:
The seafloor structures that will be encountered are shelf, slope, rise, abyssal plain, seamounts, and mid-ocean ridge/rift valley.
Explanation:
The Atlantic Ocean is the second-largest ocean in the world. It is divided into two subdivisions, the North Atlantic Ocean and South Atlantic Ocean. The North Atlantic subdivision is the one located between North America on one side, and Europe and Northern Africa on the other side.
If we were to walk from North America to Europe on the ocean floor, then the first structure we will encounter will the relatively wide continental shelf. Next will come to the slope and rise where the seafloor sharply becomes much deeper. Once we reach the bottom of the ocean we will encounter the abyssal plain, and in the abyssal plain, there are also seamounts sharply rising above the seafloor. In the central part of the ocean, we will encounter the mid-ocean ridge, which is where the rift valley is located. After that, we will encounter the same structures that we already encountered just in a reverse manner, with abyssal plain and seamounts coming first, then sharp elevation as we come to the rise and slope, and a relatively small continental shelf.

What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The water in the oceans across the globe changes its characteristics from one area to another area, or from depth to depth. There are multiple factors that contribute to changes in the properties of the water, but the most important one, that tends to heavily influence all other factors, is the temperature of the water.
The oceans, in-depth, by temperature, have a surface zone, thermocline, and deep ocean division. The surface zone is the warmest of the zones, and it is the one where waters with different characteristics mix. The zone below it, the thermocline, is the zone where the water is not mixing anymore. In this zone, the temperature sharply changes between the depth of 200 and 1,000 meters, with every 100 meters of depth meaning 1 degree Celsius less. The deep ocean is the zone that has the biggest depth range, but there isn't much of a change in the temperature and characteristics of the water in it.
