The correct answers are:
- Faults form in the lithosphere;
- Plates slide in opposite directions;
The transform plate boundaries are plate boundaries where the two or more plates are sliding past each other, moving in opposite directions. Because of the sliding, a lot of pressure is created on the plate boundary, so the earthquakes are a common occurrence. Also, something that is a characteristic of this type of plate boundary are the faults, to be more specific, transform faults. The transform faults are parallel to the plate boundary, and it can be a single one, or multiple faults parallel to one another. Their depth also can vary, from few meters to several tens of meters, or even more.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
The answer is 62 percent. <span>By 1999, after the Clean Water Act had been passed in 1970, the percentage of U.S. surface waters safe for fishing and swimming had increased from 36 percent to 62 percent. </span>
Answer:
Calcium
Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
<span>d. The percentage of the original energy from producers that's available to the consumer is quite small.
The 10% energy rule.
This energy rule states that every energy that is transferred from one organism to the other decreases by 10%. For example, a plant has created food thru photosynthesis gained 1000J and a cow eats it it would receive an energy of 100J and a human eats the cow would receive 10J.</span>
