The stratosphere contains a layer of ozone that absorbs and scatters incoming ultraviolet (UV) radiation from the sun, preventing it from reaching the Earth's surface in excessive amounts. This ozone layer acts as a shield, filtering out harmful UV radiation that can damage living organisms and ecosystems.

Rooftops get hot because they absorb sunlight and convert it into heat. The materials used in constructing rooftops, such as asphalt and metal, can also retain heat. Lack of shade and ventilation can contribute to rooftop temperatures rising.

No, butterfly fish do not typically eat sea anemones. They primarily feed on coral polyps, small crustaceans, and other invertebrates. While some fish may consume sea anemones, it is not a common part of the butterfly fish diet.

The prevailing scientific view is that the universe began with the Big Bang approximately 13.8 billion years ago. This event marked the beginning of space, time, and all matter in the universe. The universe has been expanding and evolving ever since.

Stars expand and contract in size due to the balance between gravitational forces pulling inwards and internal pressures pushing outwards. When nuclear fusion in the core of a star produces energy, it creates an outward pressure that can cause the star to expand. As the star's core exhausts its fuel, the outward pressure decreases, causing the star to contract under its own gravity.

No, the reaction between CuO and CO is endothermic. This is because energy is required to break the bonds in both reactants and form new bonds in the products.

Algae are protists that use photosynthesis to make food. They are diverse and can be found in various aquatic environments, ranging from microscopic plankton to large seaweeds. Algae play a crucial role in the aquatic food chain and contribute significantly to oxygen production on Earth.

infrared can be very helpful at nightime rescues, because infrared allows the user to see body jeat, which can not be seen with night vision goggles. infrared is more efficient only because of its ability to pick up body heat.

A virtual image appears on the same side of the lens as the object, and it cannot be projected onto a screen. It is formed when diverging light rays appear to converge at a point behind the lens.

When the amount of solute is equal to the amount of solvent, the solution becomes saturated. This means that no more solute can dissolve in the solvent at that temperature. Any additional solute added will remain as undissolved solid at the bottom of the container.

It has to overcome its' own weight and obtain a speed of 17,500 miles an hour to escape the Earths' gravitational pull. That is 3.38 x 1012 Joules. 3,380,000,000,000 joules.

Depending on where you started in Texas, generally East. From some parts of Texas you would travel North East to reach Arkansas.

Solar activity, such as sunspots and solar flares, follows an 11-year cycle known as the solar cycle. This cycle is driven by changes in the sun's magnetic field and can affect space weather and geomagnetic activity on Earth.

A regular pentagon has five equal sides and five equal angles. An irregular pentagon can have sides and angles of various lengths and sizes. A pentagon can appear in everyday objects such as a home plate in baseball or a street sign.

Many facts about stars are based on theories because stars are extremely distant and complex objects that are difficult to study directly. Scientists use theories to make predictions and explanations based on the data they can observe, such as light, temperature, and composition of stars. These theories are constantly refined and updated as more data becomes available through telescopes and other observational methods.

Scientists centuries ago believed that a nuclear reaction which was very large would be capable of producing the energy of the sun, they thought this because when they experimented with nuclear reactions and measuring the energy produced the reaction of coal not burning long without being consumed.

the particles get closer together because my class just talked about that stuff!!

CO2 provides approximately .03% of the earth's atmosphere. If you consider that the earth's atmosphere contains approximately 4.2 billion cubic kilometers - which is the "effective mass" of the atmosphere, or the mass of the entire atmosphere if measured at sea level pressure - then:

4.2 billion x .03 % = 1,260,000 cubic kilometers of CO2.

The other constant used in this equation is the "Karman Limit" of 100 miles as the upper boundary for earth's atmosphere.

well Once there was hella monkeys that came to earth and started having there babies and then once the monkeys were seatle they saw the ocean and searched for food since that they had learned how to walk

your welcome by the smartest girl ever

days and nights are caused due to the rotation of earth on its own axis. it takes about 23 hours 56 minutes and 54 seconds for earth to complete rotation once. during rotation the part of earth which faces sun has day and the part away from sun has night.

at poles days and night are of 6 months long.......when sun rays are direct on tropic of cancer there is 6 months day at the north pole and while the northern hemisphere has long days and shorter night. similar is the case with southern hemisphere. on 21st march and 23rd September days and night are equal throughout the world as the sun rays are direct on equator. areas around equator have always equal days and equal nights..............that's all i know about it

When astronauts sweat in space, the lack of gravity prevents the sweat from dripping off their skin. Instead, sweat accumulates as a liquid layer on the skin or evaporates into the air, which can lead to increased humidity inside the spacesuit. The body's cooling mechanism through sweat evaporation may be less effective in space due to the lack of gravity.

Most stars, like our sun generate light through fusion. However, the planets in our solar system appear like stars but actually are reflecting the light from our sun rather than producing light. The moon also reflects a tremendous amount of light.

stars are massive balls of gas that emit light and energy through nuclear fusion in their cores. At night, when the Earth rotates and our side faces away from the Sun, the sky darkens and we are able to see the light emitted by these distant stars in the night sky.

The sun's energy enables water molecules from the water's surface to evaporate into the atmosphere. This process forms water vapor, which eventually leads to the formation of clouds and precipitation.

The first modern astronomer to view Mercury using a telescope was Galileo Galilei in the early 17th century. His observations of Mercury, along with other planets, helped to revolutionize our understanding of the solar system.
