Answer:
Subducting forces played a crucial role in formation of the islands.
Explanation:
- These are known as the formation of Archipelago. Many thousands of islands that constitute the philippine island are an Icelandic arc and volcanic in origin.
- That is supposed to have been formed after the subduction of plates that collided together such as the Eurasian plate, Philippine Sea, and the Indo Australian plate.
- Being made up of 7,000 island groups. countries situated around the pacific ring of fire. Consist of 11 small islands while the rest are large islands that cover 90% of the surface area of the philippine plate and Luzon alone covers about 40,541 square miles.
- The original Icelandic arcs are known to have been colloidal earlier with the Sundaland forming a series of Archipelago. Melting of molten lava in the earth's crust leads to the formation of a series of chains that are seen today as the philippine islands.
<h3>Peruvian adaptations to their physical environment</h3>
Explanation:
The Peruvians adapted to their natural environment of high altitude mountains like the Andes. The mountains created environmental challenges like low temperature, decreased precipitation, poor thin soil etc.
The Peruvians utilized the mountains in the most sustainable and efficient way both for agriculture as well as irrigation purposes. They followed terrace agriculture along the high mountain regions and built aqueducts to supply water for drinking and irrigation.
The agricultural terraces were constructed in such a way it received a good amount of sunlight even though sunlight was blocked by the surrounding high mountains. The crops were spaced widely to ensure proper sunlight and crop growth.
The irrigation system through aqueducts was constructed to prevent flooding.
Answer:
Erosion breaks existing rocks and turns them into sediments. The sediments can be formed into rocks by the chemical reactions of dissolved seashells ( Calcium Carbonate.) This reaction can form sediments into rocks very quickly like the formation of concrete ( same chemical reaction). Erosion only happens on the earth's surface.
As erosion only happens on the earth's surface, sedimentary rocks are only formed on the earth's surface.
In other words:
Sedimentary rocks only found on or close to Earth's surface because sedimentary rocks are made of materials deposited in layers at the Earth's surface.
Answer:
c. meters
Explanation:
Coordinates are measured as northings and eastings. Northings are measured in meters from the equator.
Answer:
Seismic tomography
Explanation:
Seismic tomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. The data collected can be represented in a 3D image for further investigation.
