Geography
1 answer:
shtirl [24]3 years ago
4 0

Answer:

Explanation:

Hepatitis B is a viral infection. This infection attacks the liver and is a source of acute and chronic disease. It is transmitted by body fluids like blood, and can also be transmitted by sex if one is infected, or by childbirth by the infected mother. It is also transmitted if people are sharing needles or syringes. So prevention would be done by practicing safe sex, testing ourselves before we have kids, and using clean syringes and needles that nobody used before us. Besides these, there is a vaccination that is safe and works.

Most don't report symptoms when infected. But some can experience illness for several weeks and their skin starts yellowing along with the eyes, urine becomes darker, nausea and fatigue along with vomiting or abdominal pain.

Explanation:

How does this action explain the differences between seafloor crust and continental crust?

The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.

Main differences between sea floor crust and continental crusti is that oceanic crust and continental crust are less dense than the mantle, but sea floor crust is denser than continental crust. It also noticed that subduction occurs at ocean trenches, where dense seafloor crust pushes under less dense continental crust, thereby returning seafloor crust to the mantle. The subducting seafloor crust may partially melt, with lower density material melting first and erupting from volcanoes as new continental crust.

Rufina [12.5K]

Answer:

d. Temperate regions have weak thermoclines (moderate in summer, less in winter)

Explanation:

The theromoclines and how strong they are are crucial for the movement and exchange of nutrients between the surface waters and the deeper waters. The nutrients are mostly found in the deeper and colder waters, so they only reach the surface and shallower waters when the thermoclines are weaker. With the movement of the nutrients toward the surface waters, they provide nutrition for the marine organisms, resulting in much larger populations and much more species to be present. The temperate regions are the ones where the theromoclines start to become weaker because the waters become cooler, especially in the winter when the temperatures are much lower and the waters become colder as well.
