Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies.
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it. In fact, it is the leftover radiation from the Big Bang that occurred 400,000 years before the events related to this cosmic radiation.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
The incorrect statement about the cosmic microwave background is A: it is actually not a mixture of radiation from independent stars and galaxies, but the aftreglow from the Big Bang.
Explanation:The statement about the cosmic microwave background (CMB) that is not true is A) It is the result of a mixture of radiation from many independent sources, such as stars and galaxies. The CMB is thought to be evidence of the Big Bang, which is the event that started the universe.

What causes the temperature to decrease with height in the troposphere?
We have all noticed that if we hike from a place with low elevation and go up at a place with high elevation, that the temperature is gradually dropping, thus giving us a clue that the lower places are warmer, while the higher places are cooler. The reason for this, even though both the places with low and high elevation are located in the troposphere, thus the same atmospheric layer, is that the density of it is not the same everywhere. The troposphere has the highest density at its lowest points, and as the height increase the density decreases. Since the higher parts are less dense, that means that there are less gases, thus there are less molecules that are further apart from each other. This results in lesser absorption of heat, so this parts are cooler, while the lower parts are warmer because the troposphere is denser, there's more molecules that are also closer to each other, thus they absorb more heat.

This image shows a volcanic eruption in Hawaii with lava flowing into the sea.
Which statements best describe this eruption? Check all that apply.
Its magma is high in silica.
Its magma has low viscosity.
Its lava came from a quiet eruption.
Its lava sets fire to everything in its path.
Its lava came from an explosive eruption.
Answer:
- Its magma has low viscosity
- Its lava came from a quiet eruption
- Its lava sets fire to everything in its path
Explanation:
From this image, we can see that the volcano had an eruption from which it produced lava flows that managed to reach the sea. Since the volcano managed to release such large amount of lava, and the lava managed to pass several km to reach the sea, it means that the magma had low viscosity, thus it is low on silica content. Also, the low viscosity of the magma means that the gases have not been trapped in it, so the eruption of the volcano was a quite one. The lava is very hot, so it manages to set on fire everything on it path, though it immediately moves over the thing it set on fire.
Answer:
(B) Its magma has low viscosity
(C) Its lava came from a quiet eruption
(D) Its lava sets fire to everything in its path

The two main types of glacial erosion are abrasion and A. saltation. B. flowing. C. plucking. D. sliding.
Answer:
The two main types of "glacial erosion" are "abrasion and plucking".
Explanation:
Out of the three most "significant types of glacial erosion", abrasion and plucking are the most important ones. Erosion due to abrasion is said to have occurred when the ice from the glacier rakes against a rock and causes the rock to fragment down. Glacial erosion due to plucking occurs when the ice from the glacier slides between the cracks in the rocks and cause the cracks to enlarge.This action of the glacier ice eventually plucks off smaller pieces of rocks from a larger rock causing of the rock to erode.What country lies west of romania and east of austria

Why do tropical communities tend to have greater species diversity than temperate or polar communities?
Answer:
Tropical climates are better suited for a multitude of species of plants and animals.
Explanation:
The reason for this is tropical climates are easier to handle then harsh winters because almost all tropical climates are near the equator so it tends to stay warmer year round creating a year round growing period. Polar climates are harsher on the plants than the animals. Also consider this the fact that there would be no herbivore animals for predators to eat so that limits what can grow in the polar climates.

hill : No. A hill is a relatively small and round relief on a normally flat area. Not the case here... especially since the question mentions a low-relief.
mountain : No. A mountain is a big relief, much bigger than a hill... with steep sides and a summit... again, nothing like a low-relief.
plains : No. Although plains are also flat, they are low-elevation, think about fields for growing crops.
plateau: Yes. A plateau is a relatively flat (low-relief) that is significantly elevated compared to its surroundings. Drops from a plateau is usually the best scenario for a waterfall, like on this picture.

How big is the Great Pacific Garbage Patch 2018?
Answer:
1.6 million square km
Explanation:
The Great Pacific Garbage Patch is an excellent proof of how much the humans are damaging the environment, and how little they actually care about it. The biggest ocean on the planet, the Pacific Ocean, has a garbage patch that is estimated to be 1.6 million km in size. To put into a perspective, that's approximately twice the size of Texas. That data is from 2015 though, so the chances are that in the present the garbage patch is even bigger. The Great Pacific Garbage Patch comes to literary be a slow moving island of garbage. It is around 3.5 meters deep, and it contains around 7 million tons of garbage, the majority of which is plastic. This garbage patch actually has so much plastic that it outnumbers the plankton in the Pacific Ocean. The fish that lives around it, as well as the other marine life, are badly affected, and around 8% of them actually have plastic in them because of it.

Which of the following geologic events can occur at a transform boundary?a. Earthquakeb. Mountain formationc. Volcanic eruptiond. Rift formation
Answer:
a. Earthquake
Explanation:
The transform fault plate boundaries are plate boundaries that are formed where there's plates to slide past each other. Basically there's no real collision between the plates because they move in opposite directions but parallel to one another. Despite the lack of direct collision, the plates still create a lot of pressure between each other on the contact zone. This intense pressure results in the formation of cracks in the crust, some of which are parallel to the boundary and are manifested on the surface as faults, while some are cracks deep inside the crust and create adjustments. The adjustments of the crust deep inside it release lot of energy, and that energy is manifested through strong, destructive vibrations, known as earthquakes.
Final answer:
An earthquake is the geologic event typically associated with a transform boundary, such as the San Andreas Fault in California. Transform boundaries involve lateral plate movement, leading to earthquakes when built-up strain is released.
Explanation:
The geologic event that commonly occurs at a transform boundary is an earthquake. At transform boundaries, two tectonic plates slide past one another. This lateral movement can build up strain in the adjacent crustal regions, leading to earthquakes when the strain is released and the plates grind against each other. A well-known example is the San Andreas Fault in California. Transform boundaries are not typically associated with mountain formation, volcanic eruptions, or rift formation, as these events are more common at convergent and divergent plate boundaries. Volcanic eruptions generally occur at divergent plate boundaries, like mid-ocean ridges, or at convergent boundaries where subduction takes place. Mountain formation is also mostly linked to convergent boundaries where two plates collide. Finally, rift formation occurs at divergent boundaries where plates move away from each other.
