Oceanic crust is constantly being recycled by subduction into the mantle at convergent plate zones and creation at mid-ocean ridges. Continental crust is not subducted, therefore its old age.
Areas of underwater ground are called seabeds or ocean floors.
Continents, Islands
Young rivers are straighter and more narrow. Old rivers have many meanders (bends in a rivers channel), and young rivers do not they are fast and have a high gradient, unlike old rivers which are slow and have a shallow gradient.
The land masses that the Earth is divided into are called continents. There are seven continents on Earth: Africa, Antarctica, Asia, Europe, North America, Australia, and South America.
Yes, a young river typically erodes more than an old river because young rivers have a steeper gradient, higher energy, and are still shaping their course. Over time, old rivers tend to have a more established path with reduced erosional power.
Kitts are the young of small felines (the young of large felines are called cubs). And as felines are found on all continents except Antarctica (due in part to man importing them as house pets), kittens are to be found on all continents except Antarctica.
mid-ocean ridges and subduction zones
No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.
The New World are the continents of North and South America while the Old World has the continents Asia, Europe, and Africa.
The original question was too long to copy in. It was: "The sum of the ages of Old and Young is 48. Old is twice as old as young was when old was half as old as young will be when young is three times as old as old was when old was three times as old as young How old is old?" There is a rather strenuous algebraic solution.The answer is :Old is 30, Young is 18When Old was 18, Young was 6; when Old was 27 (1/2 of 54), Young was 15, and Old is twice that.If you change the sum to 32, then the ages become 20 and 12.When Old was 12, Young was 4; when Old was 18 (1/2 of 36), Young was 10.In each case, Old is always 5/3 as old as Young and 5/8 of the sum.
Africa, Europe and Asia.
The opposite of old is young.
The antonym for old is young.
* To get a numerical answer, you would need to know the sum of their ages, which was given as 48 in the original form of this question, where Old is 30, Young is 18.When Old was 18, Young was 6; when Old was 27 (1/2 of 54), Young was 15, and Old is twice that.If you change the sum to 32, then the ages become 20 and 12.When Old was 12, Young was 4; when Old was 18 (1/2 of 36), Young was 10.In each case, Old is 5/3 as old as Young and 5/8 of the sum of their ages.---Old = 2 * Young when Old was 1/2 [3 * (3 * Young)](see the related link for one solution)
Areas of underwater ground are called seabeds or ocean floors.
The algebraic solution gives the age of Old as 5/3 Young, so there is no integer answer. The original form gave a sum of 48, which gives the integral solution Old = 30, Young = 18 Using 49, you get Old = 245/8 years (30.625) Young = 147/8 years (18.375)
4 years young...
