Plants need carbon dioxide gas to perform photosynthesis and make food.

Heres a successful real answer water on earth will always exist water evaporates and rain is everywhere in every state to country and it will never stop the cycle happy to help

Approximately 71% of the Earth's surface is covered by water. This includes oceans, seas, lakes, rivers, and other bodies of water. The majority of this water is in the form of saltwater in the oceans.

Cirrus clouds are thin and wispy high-altitude clouds that typically do not produce rain. Instead, they are made up of ice crystals and are often associated with fair weather.

Oil and gas are used in everyday life for various purposes such as transportation (fuel for cars, airplanes, and ships), heating homes and buildings, generating electricity, manufacturing products (such as plastics and synthetic materials), and even in some cosmetic and pharmaceutical products. Oil and gas play a crucial role in the global economy and are integral to many aspects of modern living.

The contact between an old eroded rock surface and a new rock layer is typically referred to as an unconformity. Unconformities represent gaps in the geologic record where erosion or non-deposition has occurred, leading to a break in the sequence of rock layers. These features are important for understanding the relative timing of events in Earth's history and can provide insights into past environmental conditions.

One would think that if a hole is drilled, eventually we will reach the other side of the earth. But actually doesnot happen. The earth's crust is supposed to be made of molten iron at a very high temperature and also the acceleration due to gravity, g, is zero at the centre of the earth.

So, most probably the chances are that if an object is able to reach the centre of the earth (assuming that it is not burnt in the high temperature), the cbject will stay at the centre of the earth as acceleration due to gravity is zero.

You would also create the largest volcano ever, resulting in the destruction of the planet. Drilling a hole that deep (literally thousands of miles) would release all the magma pressure deep in the Earth. BOOM!

Man-made gases such as tear-gas, chlorinated hydrocarbons and their ilk.

OXYGEN. That was made by plants, long after the Earth began.

In fact, the first oxygen appearing in the atmosphere came from bacteria about

3.5 billion years ago.

Some interesting facts about graphite are that it shares the same chemical composition as a diamond, but not atomic structure. Also graphite is brittle, smudges if handled, and can be used as a conductor for electricity.

The type of rock depends on how the volcano erupted and how quickly the lava cooled. Gaseous lava that is cooled is pumice, a stone so light it floats on water. Thick, slow moving lava hardens into rhyolite. Volcanoes in the Hawaiian islands sometimes have their lava cool quickly, forming a smooth, glassy black rock called obsidian. These are all classified as igneous rocks.

Summer Solstice marks the first day of summer (June 21), thus the longest photoperiod of the year. Winter Solstice marks the first day of winter, and the sun reaches it's lowest position in the sky throughout the whole year, so we expierence the shortest photoperiod of the year.

A mineral that is soft and easily broken, such as calcite or gypsum, would most likely be changed the most after being placed in a container and shaken for 10 minutes. These minerals are not very durable and can be easily broken down into smaller pieces through mechanical agitation.

Protists can exhibit both autotrophic and heterotrophic modes of nutrition. Some protists are autotrophic, meaning they can produce their own food through photosynthesis, while others are heterotrophic, feeding on organic matter produced by other organisms.

Rain and snow are two forms of precipitation that return water to Earth's surface. Rain is liquid water falling from the clouds, while snow is frozen water crystals that fall as flakes.

Seismic waves called "S waves" shake the ground up and down as they move through the Earth. S waves are a type of shear wave that travels through the Earth's interior and are responsible for the side-to-side or up-and-down motion felt during an earthquake.

Then all animals that feed on plants, herbivores, would disappear. After which all animals that feed on the herbivores, carnivores and omnivores would disappear. Basically most of life on earth would go extinct, only bacteria and other simple organisms would survive. Also us humans wouldn't be able to stay healthy if there isn't enought plants to feed on(vegtables). Also plants provide us with oxygen, which is very important for respiration. without oxygen how would the organisms respire?

The earth has roughly 5 billion years left before the farthest limit of its life as a planet as far as we can project currently; that is roughly the time that the sun will expand into a red giant [it is not massive enough to become a supernova] and either totally destroy the earth physically, or at least render a hopelessly barren and burned out cinder. Well before that time, probably within the next one billion years, the slowly increasing temperature of the sun will cause the earth to grow hotter and hotter, and the earth will lose all of its water. If we have not managed to figure out a way to survive post-earth by then, it will be the complete end of earth-based human life.

Sandstone is a sedimentary rock formed when grains of sand are deposited and subsequently compacted into rock by the pressure of overlying deposits and by the cementing effect of various other chemicals. The minerals found in sandstone will be whatever minerals were in the original grains of sand that formed the rock, chiefly quartz, and usually feldspar. Any number of other trace minerals will be found, depending upon the original source of the sand. The minerals that cement the sand particles together with likely be calcium carbonate, calcite, and silica.

A landform is naturally formed feature on earth's surface.

Lichen are one of the first organisms to colonize exposed rock in the early stages of primary succession. They can break down the rock and contribute organic material to the soil, helping create conditions for other plants to establish and grow.

One prominent figure who believed in a flat Earth was Samuel Rowbotham, who wrote under the pseudonym "Parallax." He proposed the theory of "Zetetic Astronomy" in the 19th century, arguing that Earth is a flat disc with the North Pole at the center and Antarctica forming the ice wall around the edge.

The study of potential incoming Martians or extraterrestrial life falls under the field of astrobiology. Scientists in this field explore the possibilities of life beyond Earth, including the potential for life on Mars or other celestial bodies in our solar system. Research includes studying extremophiles, examining meteorites, and conducting missions to Mars to search for signs of life.

The Earth has an atmosphere to protect life by providing oxygen for living organisms to breathe and to regulate the planet's temperature by trapping heat from the sun. It also shields the Earth from harmful radiation and meteoroids.
