Although the best main cause of mass extinction is suspected to be a massive asteroid impact it is also estimated that volcanic events like explosions and lava seem to have created much more deaths and increased the rate of destruction by a much further extent.
It is suspected to be in about 4 mass extinction events while asteroid impact is suspected to be in just 1.
Although there could be a number of factors amounting to mass extinction and there could be multiple differences in their occurrence but there is one big similarity between them. All of them are said to have permanently brought a change in the systems of how the Earth works whether it is the climate, the ecology, the land, and the water, and almost everything.

What would happen if plastic got into the ocean?
Answer: the plastic would very slowly decompose this will inevitably lead to pollution in such places.
Explanation: brainliest please
Answer: Once the plastic is in the ocean, it decomposes very slowly, breaking into tiny pieces known as microplastics, which can enter the marine food chain and become incredibly damaging to sea life. The main source of ocean plastic pollution is land-based—80% of plastic in the ocean originates on land.

tropical rainforests have high species richness, but low density. in deciduous forests the pattern is the opposite. which of the statements is not a plausible explanation for this pattern?
Because there are fewer trees per hectare in temperate zones than in tropical rainforests, there are fewer species there.Similar to temperate deciduous forests, not every location in the planet undergoes seasonal change.
While some are perpetually covered in ice, others enjoy warm sunshine all year long. We who live in temperate climates experience seasonal changes every several months in rainforests . In July, you might be swooping across a lake on water skis, and six months later, you might be gliding across it on ice skates. When you have four seasons to experience each year as a child, you start to observe and value the seasonal ebb and flow of life all around you. Animals that don't migrate remain tucked up in warm dens throughout the winter, waiting for spring. When the snow melts and the trees' leaves blossom, life returns and gets ready for a new year. Spring is a wonderful rebirth.

compare the weather conditions in high air pressure and low air pressure situations
Clear skies are typically linked to high-pressure systems. low air pressure weather pattern that is typically brought on by warming. Storms and low-pressure systems frequently coexist.
Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure. It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. A barometer is frequently used to measure atmospheric pressure. A mercury column in a glass tube acts as a barometer, rising or falling in response to changes in the atmosphere's density. By measuring how much the mercury rises, meteorologists can determine the atmospheric pressure.

Light absorbing molecules used by plants to absorb the sun's energy.
Light absorbing molecules used by plants to absorb the sun's energy is chlorophyll.
Any of several closely similar green pigments called chlorophyll can be found in cyanobacteria as well as in the chloroplasts of algae and plants. Its name is derived from the Greek words "khloros" and "phyllon," which both mean "pale green" ("leaf"). Plants can absorb energy from light thanks to chlorophyll. In the blue and red parts of the electromagnetic spectrum, chlorophylls absorb light most effectively. Green and near-green wavelengths, on the other hand, are poorly absorbed by it. Thus, tissues rich in chlorophyll appear green because less green light is absorbed and is instead diffusively reflected by components like cell walls. The photosystems of green plants contain two different forms of chlorophyll: chlorophyll a and b.

For example, an object that has low ________ is lightweight for its size and an object that has high ________ is heavy for its size. Density is an important property of ocean water because it determines the water's vertical position in the ocean.
An object that has low density is lightweight for its size and an object that has high density is heavy for its size.
Density refers to a measurement of material's mass per unit of volume. The density of material is the denseness of the material within a specific area. In other words, it is essentially a measurement of how tightly matter is packed together and is a unique physical property of a material. The principle of density was discovered by the Greek scientist Archimedes. The formula for density is given as d = M/V, where d is density, M is mass, and V is volume. It is a measure of how heavy something is for its size. Hence, if something is heavy for its size, it has a high density. If an object is light for its size it has a low density.

what strategy would increase the threat of climate change? group of answer choices shift from fossil fuels to a mix of carbon-free energy resources improve energy efficiency stop cutting down tropical forests capture and store as much carbon dioxide as possible continue with current practices
Responding to climate change involves two possible approaches: reducing and stabilizing the levels of greenhouse gases (“mitigation”) and adapting to the climate change already in the pipeline (“adaptation”).
One of the most challenging concerns we face today is climate change. It has numerous facets, including science, economics, society, politics, and moral and ethical issues. It is a worldwide issue that will persist for many millennia. The globe (and notably the ocean) takes a while to adapt to warming because carbon dioxide, the heat-trapping greenhouse gas that is the main cause of modern global warming, persists in the atmosphere for many thousands of years. Therefore, even if we completely ceased generating greenhouse gases today, future generations would still be impacted by global warming and climate change. Humanity has thereby "committed" itself to some degree of climatic change.

The tectonic plates activity on a planet is controlled by the amount of heat that is stored in the interior parts of planets after formation. if there is larger the amount of heat, the more energy stored is transfered to the surface in the form of geological activity.
