What does magnetic striping tell us about the age of rocks?
If you know how many stripes away from the mid-ocean ridge the rock is and you know how frequently the earth's poles flip you can use the stripes like rings on a tree to measure the age of that rock.
What happens when you move roks away from the ocan ridge?
When rocks are moved away from the ocean ridge, the gap created is eventually filled by magma rising up from the mantle below. This process is known as seafloor spreading, where new oceanic crust is formed as magma solidifies and creates a new ocean floor. Over time, this continuous spreading and creation of new oceanic crust causes the ocean basin to widen.
What patterns occur in the bands of color on either side of ocean ridge?
The bands of color on either side of an ocean ridge represent the age of the seafloor, with younger rocks closest to the ridge and older rocks further away. These bands typically show a symmetrical pattern, indicating that new crust forms at the ridge due to volcanic activity and then spreads outward. Additionally, variations in color can reflect differences in mineral composition and sedimentation over time. This pattern is crucial for understanding plate tectonics and the dynamics of Earth's lithosphere.
How old is io in years?
I am a digital assistant and do not have a physical form or age.
How did scientists determine the difference in the age of rocks near mid ocean ridges from those farther away from ridges?
Good question: Geologist use these methods to determine the ages of rocks. The absolute age of the rock and relative age of the rock. Now because the mid ocean ridges are place of divergent where plates move apart, the rock farther away from the ridges are older than the younger ones that are just form close to the ride. This is called relative dating. The absolute dating use Isotopes and radiometric dating meaning they have to have a hand sample to determine this. But I think the best method here for situation like this is the Relative ages of the rocks.
What observation has been made about the age of the basalt that forms a mid ocean ridge?
New magma of basalt composition emerges at and near the axis because of decompression melting in the underlying Earth's mantle.
Did the ice age cause salt to form in the oceans?
No. Salt is washed into the ocean from rivers and picked up from rocks.
How many floors are in Dark Crater in Pokemon explorers of time?
dark crater has 15 floors then you are in the middle of the dungeon then its 14 floors to darkrai and i am not sure how much hp darkrai has manuel age 7
What kind of mountains form from hot spots?
Hot spot volcanos. As these age they can become island chains and eventually subsurface seamount arcs if the hot spot is in the ocean.
How does the age of seafloor sediments change the increasing distance from the ocean ridge?
age increases
Where in Miami can I get my hardwood floor refinished?
Hardwood floors are popular for their durability and timelessness. After all, some of the oldest homes in the country, dating back to early colonial times, still have their original hardwood floors. Hardwood floors are probably the only flooring choice that can grow to look better with age.
How does an ice age affect the ocean?
During an ice age, large ice sheets form on land, causing global sea levels to drop. This leads to changes in ocean circulation patterns and can affect marine ecosystems. Additionally, the lower sea levels can expose new areas of the continental shelf, affecting coastal habitats and marine life.
What is the origin of Escrima?
The origin of Escrima a Philippine art form that is believed to have originated in India. It is possible that it started when ocean levels were lower during the last ice age and stayed on the islands when they were created by the rising ocean levels; covering the land bridges and isolating the people.
How old does a penguin have to be travel to the ocean?
age should have to restrictions
During the age the ocean levels were than now?
Lower
When was the earliest discovered use of concrete dated?
5600 bc at Lepenski Vir in Yogoslavia in hut floors of stone age village
What do you think might happen to the ocean if global temperatures decreased?
It is possible that more ice burgs would form, which then would lead to shore line decreasing. If fell enough another ice age
