Question
1. Look up New Horizons space probe. Where is it heading and where is it right now?
2. Where are the tallest and longest mountain chains on Earth? How were they formed?
3. How do we know that tectonic plates move?
Describe how transform plate boundaries differ from plate boundaries.
What form of geologic activity is exhibited along transform boundaries?
4. On what tectonic plate do you live?
How many adjacent plates are there to the one you live on?
In which direction are these plates moving?
5. If the Mid-Atlantic Ridge opens up at the rate of 5 centimeters per year, how much farther apart will Paris and New York be in 1,000 years (show your work for full credit)?
6. Mount Everest is now approximately 8,850 meters tall, and it has been growing taller at a rate of about 2 centimeters per year. Estimate the approximate age of the mountain.
Explanation / Answer
1)New Horizons is a NASA spacecraft, launched in 2006 headed for the dwarf planet Pluto. It scooted by Jupiter in 2007, and and conducted a six-month-long exploration flyby study of Pluto and its moons in summer 2015, culminating with Pluto closest approach on July 14, 2015. Now the spacecraft is expected to head farther into the Kuiper Belt to examine another of the ancient, icy mini-worlds in that vast region, at least a billion miles beyond Neptune’s orbit.
2) The tallest mountain chain is the Himalaya’s. The highest peak on Earth, Mount Everest is located on this mountain range. The Himalayas include more than one hundred peaks over 7,200 m high. The range extends over 2,400km and was formed from the subduction of the Indian tectonic plate under the Eurasian plate.
The longest mountain range in the world is the Andes, which extends around 7,000 km along the west coast of South America, from Southern Argentina to Venezuela. Mt. Aconcagua, height around 6900 m is the highest peak in this range. The Andes were formed by Nazcan and Antarctic tectonic plates being subducted underneath the South American Plate. However, if undersea mountain ranges are included, then the mid-ocean ridge system becomes the longest mountain range in the world, stretching several times longer than the Andes.
(3) Nowadays,we can use GPS to measure the relative separation of locations on the surface of the Earth. These measurements allow us to track movement even as small as millimeters per year. Mapping out these motions clearly shows the aggregate motion of the underlying plates.
Transform Plate Boundaries are locations where two plates slide past one another. They lack the compressive or tearing forces associated with convergent or divergent boundaries.
Transform boundaries exhibit earthquakes associated with the sliding of the two plates, often resulting in long valleys and other linear features.
(4) To answer this question I require to know your location(country). I am located in the Indian plate.
(5) Mid-Atlantic Ridge opens up at the rate of 5 centimeters per year
So, 5 cm/yr × 1000 yrs = 5000 cm = 50 m
(6)Age of the mountain= (8850 m ×100 cm/m)/2 cm/yr = 442,500 yr
