Hello!
The garbage patchs are a site with high concentrations of trash. They are formed by the ocean gyre, where the ocean have convergences zones forming a circle of currents. When the garbage join the circle, it can't go out, cause the currents make a kind of a permanent "wall".
We can locate garbages patchs in the South Atlantic Gyre, Indian Ocean Gyre and the South Pacific Gyre.

The general flow of air from the the poles to the equator occurs in the stratosphere.
The Red Sea and the Suez Canal are of strategic value in the region because this is one of the most important transport points for oil in the entire world. Much of the oil that comes from the Persian Gulf travels through the Suez Canal on its way to Europe and the United States. Control and stability of this area is of vital importance to the United States and European governments and markets.
Answer: B. Glaciers are thick sheets of recrystallized ice.
D. Glaciers last throughout the year.
Explanation:
A glacier is a continuously moving ice mass. It is formed over many years in regions where snow falls more quickly than it melts and evaporates. They are not stationary, but move due to their weight.
A high number of glaciers exist in mountainous regions but glaciers are not limited to these areas. They also do form on land.
Glaciers currently cover about 10% of our planet, down from the last Ice age when 32% of land was covered in ice.
Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.
Seismic waves are recorded by a machine called a seismograph, which tells us about the strength and speed of the seismic waves. ... Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.
