The term slash and burn applies to what area?
Slash and burn refers to the agricultural practice of clearing land by cutting down vegetation and burning it before planting crops. It is commonly used in tropical regions for subsistence farming and can have negative environmental impacts such as deforestation and soil degradation.
How do you see things that don't give out their own light?
We see objects that don't give out their own light by reflecting light from another source, such as the sun or artificial lighting. Our eyes detect the light that is reflected off these objects, allowing us to see them.
The atmosphere on Mars is 95.72% Carbon Dioxide.
What celestial object shows phase changes?
We see the moon change phase over a period of about a month. It begins full, becomes less full, becomes a crescent, then there is no moon. Then a sliver will appear, and that sliver will grow until it becomes a full moon once more.
The planet Venus, as viewed from earth, will also show a progression from a tiny disc, to a larger "half-moon" effect, to a very large crescent (when Venus is at it's brightest as seen from earth).
3 reasons why the earth is round?
- The curvature of the Earth can be observed through the way ships disappear over the horizon.
- The Earth's shadow on the moon during a lunar eclipse is curved, indicating a spherical shape.
- Satellite images show a round Earth with consistent curvature across the globe.
What is caused by your tilted axis and your orbit?
Earth's tilted axis and orbit around the sun cause the changing of seasons. The tilt of Earth's axis means that different parts of the planet receive varying amounts of sunlight during different times of the year, resulting in the familiar cycle of spring, summer, autumn, and winter.
What is monoceros distance from earth?
Monoceros' primary star - Alpha Monocerotis - is 144 light years from Earth.
Explain why it is that we have periods of night and periods of day on earth?
Day and night occur on Earth due to the rotation of the planet on its axis. As the Earth rotates, different parts of it are exposed to the sun's light, causing day in those regions, while the opposite side experiences night. This cycle of day and night is a result of the Earth's rotation every 24 hours.
What are the problems that earth is facing now?
POLUTION is the main problem reflect.....
a simple small dirth can cause a lot of damages
did you already threw a trash not in its proper places?
sure you did many children want to see a SMOG free world
a better and clean world when will you change ? when all the ice had melt
and no animals are living or when you can't breathe because of carbon dioxide?
Where can you find a timeline of the ages of earth?
You can find a timeline of Earth's ages in geological textbooks, scientific publications, or on reputable websites maintained by geological organizations or institutions. These timelines typically outline the major geological time periods, eras, and epochs spanning from the formation of Earth to the present day.
What does planetary common good mean?
Planetary common good refers to the well-being and rights of all individuals and societies on Earth, taking into consideration the sustainability of resources and ecosystems for future generations. It emphasizes cooperation and collective action to address global challenges such as climate change, poverty, and inequality.
What does the rigid crust and uppermost mantle form?
The rigid crust and uppermost mantle form the Earth's lithosphere. This outermost layer is divided into large pieces called tectonic plates that float on the semi-fluid asthenosphere below. The interaction of these plates is responsible for shaping the Earth's surface through processes like earthquakes and mountain formation.
Did socrates say that the earth is round?
Socrates lived in ancient Greece and did not specifically address the shape of the Earth in his writings. The idea that the Earth is round was proposed by other ancient thinkers such as Pythagoras and Aristotle.
Which body exerts the weakest gravitational force on the earth?
We keep getting these questions about one body 'exerting' gravitational force
on other bodies, and we have to emphasize again: That's the least helpful way
to think about it.
Gravitational force always involves two bodies. The strength of the force depends
on the mass of both bodies, the force acts along the line between the centers of
both bodies, and both bodies feel gravitational forces with the same strength.
Whatever force the earth 'exerts' on you that draws you toward it, you exert the
same force on the earth that draws the earth toward you.
The weakest pair of gravitational forces is the pair between the earth and the
smallest mass that's farthest away from the earth. So it has to be something like
the smallest piece of dust on a bookshelf on the farthest planet in orbit around the
farthest star on the far side of the farthest galaxy from us.
How far is the earth from the sun in Yards?
Circumference is a measure around the outside of the circle using a linear measure, such as Feet or Miles. All circles have 360 degrees. The earth is divided into Lattitudes of 24 divisions that represent the 24 hours of a day. As the Earth rotates, the sun makes crosses the 24 lattitudes.
What does algae replenish in the atmosphere?
Algae help replenish oxygen in the atmosphere through the process of photosynthesis, where they take in carbon dioxide and release oxygen as a byproduct. This process is crucial for maintaining the balance of oxygen levels in the atmosphere.
What did the earth look like when it was formed?
The Earth Was a big round ball.Just like it is now. The earth was formed by a big bang.
The Earth Was a big round ball.Just like it is now. The earth was formed by a big bang.
The big bang was formed by a G-D who created all of the universe for us too stare into space and to say how amazing our universe is
How is a fossil like a time capsule?
A time capsule is something that captures a certain characteristic or "thing" from an era. When you ask how a fossil is a time capsule, - It is usually thousands of years old - On it is imprinted something unique from that time period Thats the best i got
On planet earth there is no centrifugal force at the?
At the center of the Earth, the centrifugal force is zero because all mass is evenly distributed around that point, resulting in a gravitational force that is balanced. As you move away from the center, both gravitational and centrifugal forces increase. At the surface of the Earth, the centrifugal force is present due to the rotation of the planet.
What is the Earth's mean temperature?
Currently it is 14.6 °C up from 13.9 °C 100 years ago. This is the average over the whole planet over the entire year.
The average temperature on Earth is about 13oC. Highest recorded has been 56.7oC and lowest -89oC. These temperatures are dry bulb temperatures.
Most of the Earth is subject to heating and cooling by the oceans and the atmosphere. Except for extreme locations on Earth (deserts, poles), the temperature range is compatible with human activities, falling in the range between -40° and +40° C (-40° to 104°F).
Temperatures tend to be hotter near the equator, or when it is summer at a given location. Ocean and air currents also affect the range of temperatures. Climate change scientists estimate that ever-increasing levels of manmade carbon dioxide could raise global temperatures by up to 6 degrees C over the next 50 years.
Core Temperature
The temperature of the Earth is approximately 5500 degrees Celsius at its center and heat continuously flows toward the surface. The temperature of the Earth increased with its increase in mass because the new size triggered an increase in its gravitational force of attraction and caused the Earth to compress. Some of the internal heat comes from radioactive decay.
Very hot in the centre, gradually cooling as you move to the outer layers, pretty cool on the outside, coldest at the top and bottom where the polar bears and penguins live, and nicest for sunbathing right around the fattest part in the middle. Could you be a little more specific?
When did you come on the planet earth and why?
I have been here all of my life, and so were my parents. THEIR parents, however,
came from different far-away places, and settled here because opportunity and
freedom were here, and also because communities of people like them, from their
ancestral homes, already existed here. By definition, they were all aliens when
they arrived, but each of them soon won citizenship.
My mass is always the same, no matter where I am or what I am doing.
My weight, however, depends on other masses in my environment.
You have said that the asteroid is much smaller than Earth, but you haven't
said a thing about its mass, which is roughly just as important as its size.
Most likely, I weigh much less there than I do on Earth, but I can't guarantee
that. If the asteroid has enough mass packed into that slender body, I could
easily wind up weighing more there than on Earth.
How can you take care of the planet?
You can all save the planet, each and every one you, rich and poor, portly and poorly, carefree or careful, in so many ways. You can start by small changes, such as organizing your recycling, make sure the right waste goes in the right bins and dispose of all items properly.
For example, make sure you don't try and recycle polystyrene- the chemicals inside it can mix with other potential waste. Contact a recycling facility in your area that will accept polystyrene. And, when printing paper at work, however much you want your paper to look very nice- always go for a small (but readable,) font, with a small letter-spacing, to use less pages, and print less. Several books have been published on the subject, possibly the best of which a book by Joanna Yarrow '1001 ways to save the planet'. It gives 1001 short, quick and easy fail-safe ways of leaving a small carbon footprint, from giving you advice on proper recycling methods, to things that you can use a composter for, to the most obvious of things, such as, turn things off at the switch at night, and don't ever leave any appliances on standby. Yarrow's book is an inspirational guide-book, that should be read, at all costs, and should be owned by every person in the planet. To top it off, each copy is made from recyclable paper, that can be recycled again when you're done with it. Truly, a book for a book.
What banged in earths big bang?
The "big bang" predated the Earth by about 8 billion years.
The biggest bang that the Earth had was with a sister planet about 4.7 billion years ago which resulted in the formation of the moon (and the rotation of the Earth - i.e. day and night).
