B. mountains
C. coastlines
D. dunes
E. elevation

Answers

Answer:

B,C and D

Explanation:

These are landforms because if you were to travel to the location they were seen on the map they are visible

however Elevation is not a visible mass ( it is a characteristic of a location ) and geosphere is a general term to describe the sections of the earth and atmosphere

Hope this helps!

The three examples of landforms among the options provided are mountains, coastlines, and dunes.

What are landforms?

Landforms are natural features on the surface of the earth, such as mountains, valleys, plains, and coastlines, that have been shaped by various geological processes over time.

Mountains are large natural elevations of the earth's surface, while coastlines are the landforms where the land meets the sea, often characterized by cliffs, beaches, and bays. Dunes are hills of sand that form in deserts or near beaches due to the movement of wind.

The geosphere refers to the solid, rocky part of the earth's surface, which includes the lithosphere (outermost layer of the earth's crust) and the underlying mantle, and is not considered a landform. Elevation is a term that refers to the height of a landform relative to sea level, rather than being a landform itself.

What are some of the posible signals of male quality in widowbirds and what information might they convey? What are the females choosing and why

Answers

Male produces signals of bright red, yellow epaulets and long tails.

Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.

The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.

What can you infer about the position of the galaxies 100 million years
before this telescope photo was taken? How does this relate to the big bang
theory?

Answers

Although the picture for this question is not given, if we have the possibility to view galaxies from 100 million years ago and compare them to the photos we have today, we would see that their positions would be different.

Why would the position of the galaxies have changed?

This has to do with the fact that the universe is always expanding.

The idea of an expanding universe means that galaxies are moving farther away all the time.

However, due to the effects of gravity, some galaxies pull each other in and form groups or clusters.

Therefore, due to the formation of galaxy groups or clusters, the position of galaxies may have changed in relation to others from outside its groups in the last 100 million years, while remaining the same relative to other galaxies in its local group.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement
best describes an environmental consequence of this process for ecosystems?
O Wastewater is contaminated with oil and becomes sludge in landfills
O Water vapor is released into the air, which is considered a greenhouse gas,
Heavy metals are released into surrounding soil, poisoning local vegetation
O Billions of gallons of water are pulled from surrounding areas

Answers

The correct answer is that chemicals added to the liquid can contaminate groundwater.

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.  

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.
