A Plate Is Moving At A Rate Of $4 \frac{cm}{yr}$ Toward Another Plate That Is $10,000 \, Km$ Away. In How Many Years Will The Plates Collide?A. 250 Million Years B. 2,500 Years C. 25 Thousand Years D. 250,000 Years
Introduction
Plate tectonics is a fundamental concept in geology that describes the movement of the Earth's lithosphere, which is broken into several large plates that float on the semi-fluid asthenosphere below. These plates are in constant motion, sliding over the more fluid asthenosphere below. The movement of these plates can result in various geological phenomena, including earthquakes, volcanic eruptions, and the creation of mountain ranges. In this article, we will explore the concept of plate collision and calculate the time it takes for two plates to collide.
Plate Movement and Collision
The movement of tectonic plates is a slow process that occurs over millions of years. The rate at which plates move can vary greatly, ranging from a few centimeters per year to several meters per year. In this problem, we are given a plate moving at a rate of $4 \frac{cm}{yr}$ toward another plate that is $10,000 , km$ away. To calculate the time it takes for the plates to collide, we need to convert the distance between the plates from kilometers to centimeters.
Conversion of Distance
To convert the distance from kilometers to centimeters, we can use the following conversion factor:
Using these conversion factors, we can convert the distance from kilometers to centimeters as follows:
Calculation of Time
Now that we have the distance between the plates in centimeters, we can calculate the time it takes for the plates to collide using the following formula:
Substituting the values given in the problem, we get:
Simplifying the expression, we get:
Conclusion
In this article, we calculated the time it takes for two plates to collide using the concept of plate tectonics and the formula for time. We converted the distance between the plates from kilometers to centimeters and used the given rate of plate movement to calculate the time. The result shows that the plates will collide in approximately 250 million years.
Answer
The correct answer is A. 250 million years.
Discussion
This problem is a classic example of how plate tectonics can be used to understand geological phenomena. The movement of tectonic plates is a slow process that occurs over millions of years, and the rate at which plates move can vary greatly. In this problem, we used the concept of plate tectonics and the formula for time to calculate the time it takes for two plates to collide. The result shows that the plates will collide in approximately 250 million years.

A Plate is Moving: Q&A =========================
Introduction
In our previous article, we explored the concept of plate tectonics and calculated the time it takes for two plates to collide. In this article, we will answer some frequently asked questions related to plate tectonics and plate collision.
Q: What is plate tectonics?
A: Plate tectonics is a fundamental concept in geology that describes the movement of the Earth's lithosphere, which is broken into several large plates that float on the semi-fluid asthenosphere below.
Q: What causes plate movement?
A: The movement of tectonic plates is caused by convection currents in the Earth's mantle. These convection currents are driven by heat from the Earth's core and cause the plates to move.
Q: How fast do plates move?
A: The rate at which plates move can vary greatly, ranging from a few centimeters per year to several meters per year.
Q: What happens when two plates collide?
A: When two plates collide, they can result in various geological phenomena, including earthquakes, volcanic eruptions, and the creation of mountain ranges.
Q: How long does it take for two plates to collide?
A: The time it takes for two plates to collide depends on the rate at which they are moving and the distance between them. In our previous article, we calculated the time it takes for two plates to collide to be approximately 250 million years.
Q: Can plate collision be predicted?
A: While plate collision can be predicted to some extent, it is a complex process that involves many variables. Scientists use various techniques, including seismic monitoring and plate boundary modeling, to predict when and where plate collision will occur.
Q: What are the consequences of plate collision?
A: The consequences of plate collision can be significant and include earthquakes, volcanic eruptions, and the creation of mountain ranges. In some cases, plate collision can also result in the formation of oceanic trenches and the subduction of one plate beneath another.
Q: Can plate collision be prevented?
A: No, plate collision cannot be prevented. The movement of tectonic plates is a natural process that is driven by convection currents in the Earth's mantle. While scientists can predict when and where plate collision will occur, they cannot prevent it.
Q: What is the significance of plate tectonics?
A: Plate tectonics is a fundamental concept in geology that helps us understand the Earth's surface processes and the formation of geological features. It also has significant implications for natural hazard assessment and mitigation.
