There is no insulating LAYER of Carbon Dioxide round the Earth.

The Carbon Dioxide is mixed up with the Oxygen and Nitrogen in Earth's atmosphere and is not present in the atmosphere as a layer.

If the absolute amount of Carbon Dioxide in the atmosphere increases, the Earth would get warmer.

Oe black, three red, and three green. the black represents the African American People, the red represents the struggle of the African American People, the green represent the hope for the future.

Microscopes have allowed scientists to observe minute details of organisms, leading to the discovery of new characteristics that aid in classification. This has helped in identifying new species, understanding evolutionary relationships, and revising existing classification systems based on morphology and cell structure.

A periscope consists of a tube with mirrors at both ends. The function of a periscope is to allow a person to see objects that are not in their direct line of sight, such as those above a wall or around a corner, by using the reflections from the mirrors to redirect light.

Coal and Oil create pollutants which affect the environment. Nuclear doesnt directly affect the environment, it creates waste which doesnt degrade meaning toxic will needed to be stored. Some people may think wind turbines aside from giving non polluting energy give 'eye pollution' because they dont look pretty. Neither does a nuclear power plant. So lets be honest its worth it.

Regions near the poles, such as the North and South Poles, experience six months of continuous daylight during their respective summer seasons and six months of continuous darkness during their winters due to the Earth's axial tilt and orbit around the sun. This phenomenon is known as the midnight sun in summer and polar night in winter.

Soilless agriculture, also known as hydroponics, is a method of growing plants without using soil. Instead, plants are grown in a nutrient-rich water solution or a soilless medium like perlite or gravel. This method allows for more control over the plant's environment and can lead to faster growth and higher yields.

Volcanism and tectonic activity have been the most important geological processes in shaping the present surface of Venus. Volcanic activity has created vast plains of volcanic rock, while tectonic forces have formed mountain belts and rift zones on the planet.

Climates can be categorized by temperature and precipitation patterns. These two features together help define the characteristics of different climate zones around the world.

Diploid and haploid cells do not have alternation of generations; this phenomenon occurs in multicellular organisms with a life cycle that alternates between haploid and diploid stages. Mutations can occur in both diploid and haploid cells, but they are more likely to have an impact in diploid cells due to their higher genetic complexity.

Is a heterogeneous mixture, because you can see all the part.

# Most pennies do not rust because they are not made of ferrous metal. They're either copper or copper-plated zinc.

# However U.S. cents struck in 1943 were made of zinc-coated steel. When the zinc wore off, the coins did rust. # Pennies wont rust mostly because they corrode and oxidize. # They tend to turn green once oxidized or the penny looks vary dirty.

A neutral object can be given a positive charge by transferring electrons away from the object, leaving a deficiency of negative charges. This can be achieved through methods such as rubbing the object with a material that readily donates electrons, causing the neutral object to become positively charged due to the imbalance of charges.

A geothermal pipe for a home generally needs to be buried at least 5-10 feet deep, but this can vary based on local regulations, soil type, and climate. Deeper depths may be required in colder climates to take advantage of more stable ground temperatures for efficient heat exchange.

India is the top producer of mica in the world, accounting for a significant portion of global mica production. The majority of mica in India is extracted through illegal and unregulated mining practices, leading to concerns about child labor and environmental damage.

Density is a measure of how tightly matter is packed. It is calculated by dividing the mass of an object by its volume. The higher the density, the more mass is packed into a given volume.

Mt Kenya is considered an extinct volcano. It last erupted over 3 million years ago. Today, it is a dormant volcano, with no recorded historical eruptions.

The inner core is solid due to pressure. With less pressure on it, the outer core is liquid.

the earth's surface is known to move because of the shifting and sliding of thick sections of rock called plates, which is where the earth's crust sits on. This movement can cause magma, gas, and ash to shoot up and cause a volcano, and also cause an earthquake when the plates shift and slide.

Fungi use two main types of asexual reproduction: budding and spore formation. In budding, a new individual forms as a small outgrowth on the parent cell. Spore formation involves the production of specialized reproductive cells that can develop into new individuals under favorable conditions.

During a volcanic eruption, materials such as lava (molten rock), ash, gases (such as sulfur dioxide and water vapor), and volcanic rocks are commonly exuded. The type and amount of materials depend on various factors, including the type of volcano, the composition of magma, and the eruption style.

• This is because in the wet climates the limestone will break apart due to the rain. And in dry climates it does nothing to the limestone. Therefore, this is why limestone can form cliffs in dry climates than wet climates.

probably spraining, breaking, or fracturing a bone.
open wound, closed wound, fracture, sprained, dislocated
Bones can be broken or bruised.
You may be referring to chronic or acute injuries.
If this is the case then a chronic injury is an injury caused by repetative stress or impact, like tennis elbow or shin splints. It's a gradual process.
An acute injury is if you fall of your bike and snap your arm in half. It's sudden.

Two types of waves are mechanical waves and electromagnetic waves. Mechanical waves require a medium (solid, liquid, or gas) to travel through, while electromagnetic waves can travel through a vacuum, such as outer space.

Marble is the historical rock used for statues. Marble was used because it is soft enough to be carved, but hard enough to survive for a while. Unfortunately, Marble is metamorphosed Limestone and as such it reacts with Acid. Acid rain has hurt many historic statues.
