Assuming that the South Atlantic began forming 135 million years ago, and has been spreading steadily ever since, calculate the full seafloor spreading rate in cm/yr at Buenos Aires (35º S latitude) (4,000 km away from the Mid-Atlantic Ridge).

Answers

Answer:

The seafloor spreading has been at a rate of 2.96 cm per year.

Explanation:

To get to the result, or rather the rate of seafloor spreading at Buenos Aires, we need to convert the km into cm as that is what is required as a unit.

1 m = 100 cm

1,000 m = 1 km

100 x 1,000 = 100,000 cm

4,000 x 100,000 = 400,000,000 cm

Now we need to divide the amount of cm with the amount of years in question (135 million).

400,000,000 / 135,000,000 = 2.96 cm/y

We get to a result that the average seafloor spreading rate at Buenos Aires in the last 135 million years has been 2.96 cm.

Mountain
Plains

Answers

Answer:

The hills are the landform that has general folds in the crust, making them slightly higher than their surroundings.

Explanation:

Mountian is not correct because the mountains are landforms that have major folds in the crust and stick out significantly in their surroundings.

Plains are not correct because they are relatively flat areas.

Hills are correct because they are landforms that have general folds, and they slightly stick out in their surroundings.

Plateaus are not correct, as they are high areas of relatively flat areas, but surrounded by mountains that are dominating the landscape.

If a polygon is rotated, which of the following characteristics of the polygon will always be the same? Select ALL that apply.
Side Lengths
Angle Measures
I Area
Perimeter
Coordinates

Answers

Answer:

Side lengths

Angle measures.

Explanation:

Polygon refers to two dimensional shapes that is created by straight line segments connected to form polygonal circuits. When rotated they have the same lengths and angle measures because it is equilateral and equiangular and rotated at 360 degrees.

This means that it has equal side lengths and equal measure angles.

The number of lines of reflection symmetry is the same as the side of polygon because it has the same length.

For example, Pentagon is a five sided polygon, when rotated, it has five lines order of symmetry. The angle of rotation is 360 degrees, therefore 369 degree is divided by the five lines of symmetry which is 72 degrees.

When Polygon is rotated, what stays the same are the side lengths and angle measures.

In all rotations of the polygon or the movement of polygon itself, the rotated image will have the same side lengths and angle measures as the main polygon.

Moving the center of rotation or altering the measure of the angle of rotation will not be transformed or changed. For rotation symmetry, the way of any regular polygon is the number of sides.

Conclusively, a polygon is known to be of a rotational symmetry

1. What is the importance of magma composition?
2. How magma is formed? Illustrate your answer.

Answers

Answer:

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.

Explanation:

. What is the importance of magma composition?

Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways.

How magma is formed?

Magma forms from partial melting of mantle rocks. As the rocks move upward (or have water added to them), they start to melt a little bit.As they rise, gas molecules in the magma come out of solution and form bubbles and as the bubbles rise they expand.

What is Air mass?

An air mass is a large volume of the air which could be as big as the two US states and also has consistent pressure and temperature throughout the region.

Air masses are identified based on whether they form over the land area or over the water surface. Maritime air masses form over the water body and are humid. The continental air masses form over the land area and are dry. Therefore, an air mass which develops over the northern Canada region is called a continental polar air mass and is usually cold and dry.

Therefore, the correct option is C.
