A gravitational force is the attractive force between two separate bodies. Gravity is related to mass so the more significant the mass, the greater the gravitational force it exerts on other objects. Also, the gravitational force of an object is dependent on distance. Gravity is where all things with mass or energy-including planets, stars, galaxies, and even light are brought toward one another. Another strong force on this earth is the nuclear force.
A strong nuclear force is what keeps the positively charged protons so close together in the nucleus of the atom. It is harnessed in atomic weapons, and to generate electrical energy in nuclear power plants. Force is an entity that pushes or pulls on a mass. Nuclear forces are only observable inside the nucleus of an atom as it holds protons and nucleons together.
The fact that you're here reading this answer could be due to two plausible reasons. First one could be your concern for our mother nature and you volunteer yourself to participate for the greater cause of survival, Or, you're just here lurking from your boring lifestyle out of your slothfulness. If you fall into the second category, you can leave right now. This topic is a global issue and definitely the most trivialized one by the general population around the globe, though certain Organisations are coming forward and educating everyone to contribute to this cause to save our home planet. End of this rant.
Now coming to the main point, You can find so much information about the do's and the dont's on Google. This answer is all about the traits that you need to adopt to make those practical methods work in our favor, check out the following solutions:
PS: There are a number of NGO's working towards this cause, you can volunteer and contribute for the living as long as you're above the ground.
The answer to this is A. it can be confusing to choose the right answer if you would not read the questions carefully. Latitude lines are known as horizontal lines. They will be very helpful in determining the various areas where countries are located. Longitude lines are those that may start from one end of the equator to the other end.
There are times when these lines would meet in certain areas around the world. It can be enough to make people understand the geographical locations of the different places better. Remember to check out the figures and numbers you will acquire to find the exact location of certain areas.
Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere.
The line that divides the earth into two parts in a horizontal manner is the equator. Take note that this is an invisible line. You will not see it if you would look at the Earth from a distance. Do remember that the closer the countries are to the equator, the hotter it gets. The equator usually faces the sun most of the time every year. Take note that those who are in the equator usually experience a consistent temperature all-year round.
It will just depend on their location if they would also experience rainy seasons or not. The countries that are located in the northern and southern parts of the Earth usually experience four seasons. Those that are near the equator do not experience all the seasons. Rather, the climate can just be sunny or rainy.
Trying to figure out how old planets are is a very tricky science. The planets formed billions of years ago so it is difficult to appropriately estimate how old planets are, but scientists have been able to get pretty close. The Earth is about 4.54 billion years old with the age being potentially 50 million years more or less than that estimate. Scientists use the Earth's crust and rocks in order to help determine a rough estimate of the age of the Earth.
Scientists have even used helpful clues from outside sources like the moon or different meteorites to help accurately pinpoint an age for the Earth. When put into perspective in consideration of the entire universe into one year, humans have only been around since the last minute of the last hour of the last day. Pretty cool!
Though Earth and Venus are seldom called Twin Planets, they are very different from each other. Earth is the third planet from the sun in the solar system while Venus is second. Venus has a higher temperature than of the Earth’s surface.
The atmosphere of Venus has no to little water while Earth has. Venus’ atmosphere is composed of 96.5% Carbon Dioxide and 3% Nitrogen while Carbon Dioxide on Earth is mostly stored on rocks that are calcite type. Earth has a rotation of about 24 hours, Venus, on the other hand, rotates in 243 days. Most volcanoes in Venus are very active compared to Earth’s volcanic activities.
This is not the sort of question to put here, where you will get a one paragraph answer. You need a book or at least a long article to describe the process whereby the Earth spawned life around a billion years after it came into existence itself . Even this would be a theory not an established set of facts. There is evidence that some form of living organism existed as long ago as 31/2 million years past.In fact, Billion year old zircon found in Western Australia contained high amounts of a form of carbon typically used in biological processes.
Increasingly complex living forms developed from molecules that could replicate themselves, just as DNA does. There seem to be two main explanations. Most believe that these organisms developed from gradual changes on Earth. Water percolated down rock into seas of iron sulphur causing a hydrogen reaction and carbon dioxide.
Ultimately the chemical that powers living cells enabled amino acids, which are the building blocks of proteins to be formed. They also formed nucleotids, the building blocks for RNA and DNA. When those molecules became able to reproduce themselves the basis for life-forms existed. The other possibility that receives serious consideration is that life forms actually came from another planet. Richard Dawkins has created a credible argument for this.
I do not understand. Doesn't the hydrosphere include ALL of the water on earth?
It takes one year or 365 days or approximately 365 and ¼ days for the Earth to complete its’ orbit around the sun, which is why we have a leap year every four years and February has one extra day. It is a circular orbit, and there is only a small variance between the neighboring and outermost points from the sun throughout the realm. The Earth travels around the sun, and at the same time, it rotates on its axis and is tilted.
The earth’ axis remains tilted in the same direction throughout the year. This means that on the pole will be directed away from the sun at one side of the orbit, and during the other half of the realm, it will be tilted toward the sun. Therefore, we have the seasons, so when the north pole is tilted towards the sun, the northern hemisphere has summer, and when it is away from the sun, we have winter.
