Which observation about the mid atlantic ridge region probides the best evidence that the seafloor has been spreading for millions of years?
The fact that there is a series of magnetic 'stripes' on either side of the ridge. They show that the earth's magnetic field has reversed several times during the formation of the rocks, and this only happened about every 5 million years. (There is some evidence that this is speeding up).

Which geological processes were involved in the formation of Iceland?
Iceland was formed by volcanic activity and the movement of tectonic plates. The island sits on the Mid-Atlantic Ridge, where the North American and Eurasian plates are pulling apart, causing magma to rise to the surface and create new land. This process, known as seafloor spreading, has led to the formation of Iceland over millions of years.
Why are Europe and North America further apart today than they were 65 million years ago?
Europe and North America are further apart today due to the process of seafloor spreading. This occurs at mid-ocean ridges, where new oceanic crust is formed as tectonic plates move away from each other. Over millions of years, this continual spreading has pushed Europe and North America farther apart.
Is coal evidence form the past?
Yes, coal is considered evidence from the past because it is a fossil fuel that forms over millions of years from the remains of plants and trees that lived long ago. The presence of coal deposits indicates that there were once lush forests in the area where the coal is found.
Explain the evidence for continental drift?
Evidence for continental drift includes the fit of the continents like a puzzle, similarities in rock formations and fossils across continents, and matching mountain ranges and geologic structures on different landmasses. Additionally, the distribution of certain species and climate indicators supports the theory of continental drift. These pieces of evidence suggest that the continents were once connected and have since moved apart over millions of years.
What did geologists of the late 1700's conclude about Earth's landforms?
that it caused sea floor spreading
How many cases have been tried with circumstantial evidence?
Millions, even cases with good physical/forensic evidence contain some circumstantial evidence and millions of cases are tried daily throughout the world based on circumstantial evidence only.
How many people in the world have Mouth cancer?
Millions of people and there will be more spreading unfortunately
How fast is the Atlantic Ocean getting bigger?
The Atlantic Ocean is widening at an average rate of about 2.5 centimeters (approximately 1 inch) per year due to the process of seafloor spreading at the Mid-Atlantic Ridge. This occurs as tectonic plates move apart, allowing magma to rise and create new oceanic crust. Over millions of years, this gradual expansion contributes to the ocean's overall growth. However, the rate can vary based on geological activity and tectonic movements.
What evidence is given that dinosaurs roamed the earth millions of years ago?
Fossils
If the isochron slope is 0.0077 what is the age in millions of years when first evidence of abundant fossils?
If the isochron slope is 0.0077, the age in millions of years when the first evidence of abundant fossils would be around 129 million years (1/0.0077). This calculation assumes a linear relationship between the isochron slope and time.
What is the voyage across the Atlantic Ocean in which millions of slaves traveled to America known as?
probably the "slave rout"
What do you think would happen if the sun fell in the Atlantic Ocean?
The sun is, of course, millions of times larger than the Atlantic Ocean. The ocean and the earth would be vaporized in minutes.
What does the time scale of life encompass-tens of millions or hundreds of millions of years?
There is evidence for life on earth at least some 3,600 million years ago. So the answer is non of the above but "thousands" of millions of years.
How did Atlantic slave trade affect societies within Africa?
It forced millions of people from their homes and transported them around the world.
Why were mother of millions introduced to Australia?
Mother of millions was most likely introduced to Australia as an ornamental plant for gardens and landscaping due to its attractive appearance. However, it has since become an invasive weed, spreading rapidly and outcompeting native plants in many areas.

Is selling on eBay easy and practical?
Yes it is easy and practical. the evidence is that millions all over the words are doing that.
