The earth's outer core is 2,300 kilometers thick.

A change in climate or natural disaster might change an ecosystem very quickly.

aircraft needed to travel the stratosphere

Approximately 2.5 secs.

A 'microwave' is an electro-magnetic radiation, in the same manner as light, and uv. radiation.

Being an electro-magnetic radiation it will travel at the speed of light, which is 'c' = 3.8 x 10^8 m/s

A troposphere layer of atmosphere is the are that we all breathe. Mesosphere in the other hand has less air pressure and high into space far from troposphere.

Using your sense of touch. For example the temperature of the air, or the humidity, or the movement of the wind. These sensory indications compose the 'feel' of the air around us.

For fertilizer.

The layer of the atmosphere closest to Earth's surface is the troposphere. It's the lowest layer and extends from the Earth's surface up to an average height of about 7 to 20 kilometers (4 to 12 miles) above sea level, although its height can vary depending on the region and weather conditions. The troposphere is where most weather phenomena occur, and it contains the air we breathe and the majority of Earth's clouds and weather systems.

a.n. & .p.m. are the initials for the Latin words, 'Ante meridian and Post meridian.

Translated from Latin into modern English.

Ante meridian = Before Noon an Post Meridian = After noon.

There is no such time as 12;00 am or 12;00 pm . Because 12:00 is noon or midnight, it neither before nor after.

Such as time as 7:30 a.m. means ;half past seven in the morning. Similarly. 8;45 p.m. means 'quarter to nine in the evening'.

It is not the Sun that Is moving across the sky, although it does look like it. No it is because Earth's rotation causing it to look as if the Sun was moving and not us. Our planets rotation makes it look as if the sun rises in the east, because we have a rotation of west to east, which causes it that appearance.

Earth's atmosphere appears blue because of a phenomenon called Rayleigh scattering. When sunlight enters Earth's atmosphere, the shorter (blue) wavelengths of light are scattered more than the longer (red) wavelengths. This scattering causes the blue light to be scattered in all directions, making the sky appear blue to observers on the surface.

It is difficult to determine the exact impact of the plan on the growth of his flowers without specific details about the plan. However, if the plan involves implementing proper watering, fertilization, and pest control techniques, it is likely to have a positive effect on the growth of his flowers. Additionally, if the plan includes providing optimal sunlight and maintaining proper soil conditions, it will also contribute to the healthy growth of his flowers.

That with which anythingis paved; a floor or covering of solid material, laid so as to make a hard and convenient surface for travel; a paved road or sidewalk; a decorative interior floor of tiles or colored bricks., To furnish with a pavement; to pave.

The shapes of continents do not fit together exactly because they have been moving and shifting over millions of years due to plate tectonics. This movement has caused the continents to break apart and drift apart from each other, resulting in their current shapes. Additionally, erosion and other geological processes have also altered the original shapes of the continents.

The Earth is not floating in space; it is actually orbiting the Sun due to gravitational forces. It is not sitting on anything specific but is instead held in its orbit by the gravitational pull of the Sun.

A wind that changes direction with the seasons is known as a seasonal wind or monsoon. Monsoons are characterized by a reversal in wind direction due to differential heating and cooling of land and sea surfaces. They typically bring heavy rainfall during one season and dry conditions during another, impacting various regions around the world, such as South Asia and parts of Africa.

There are several ways to independently verify that the Earth is a globe without relying on NASA's pictures. One way is through observations of the stars and constellations, which change as you move from one hemisphere to another. Another way is through the phenomenon of ships disappearing over the horizon, where the bottom of the ship is no longer visible before the rest of it gradually disappears. Additionally, satellite images from other space agencies, such as the European Space Agency or private companies, also provide evidence of the Earth's spherical shape.

Warm and cold sea water can mix at various places on Earth, such as in coastal areas where warm ocean currents meet colder ones or in regions where upwelling occurs. Upwelling happens when cold, nutrient-rich water rises from the depths of the ocean, often along coastlines. These mixing zones support diverse marine ecosystems and have important impacts on climate patterns.

Yes, it is true. In December, which is summer in the southern hemisphere, the tilt of the Earth causes the southern hemisphere to be tilted towards the sun. This results in longer days and shorter nights in the southern hemisphere during this time of the year. Conversely, the northern hemisphere experiences its shortest daytime and longest nighttime in December.

When waves cut completely through a headland, a feature called a sea cave is formed. Sea caves are formed by the relentless erosion of waves gradually wearing away the weaker rock layers of a headland. Over time, the waves create openings and cavities that can extend deep into the headland.

The concept of a flat Earth has existed since ancient times. It was believed by many civilizations, including the ancient Greeks and Egyptians. However, the understanding of a spherical Earth became more widely accepted from the 3rd century BC onwards, thanks to the works of astronomers such as Eratosthenes and the voyages of explorers like Ferdinand Magellan.

The Earth's procession through the Milky Way in 2012 was a normal astronomical event. It did not have any significant impact on the Earth or its inhabitants. There were some misconceptions and rumors about this event leading to catastrophic consequences, but they were not based on scientific evidence.
