Answer:

C. time for weathering of rock and development of the soil horizons

Explanation:

The primary succession is the initial colonization of a previously existing ecosystem that has been totally destroyed by some disastrous event. During this colonization, the organisms that settle in are ones that do not have any particular requirements for their survival, like the lichens and mosses. As they spread all over the area, they slowly start to influence the rocks on which they have grown, little by little weather them and providing them with organic matter. This gives rise to the first soil horizon, but it is very shallow and the soil is not well formed, so lot of time needs until the soil becomes suitable enough for the secondary succession to occur. When the secondary succession occurs it means that there's soil formed in the area, so new organisms move in, and as they do they replace the ones from the primary succession, slowly forming a new ecosystem and well balanced ecological community.

How are earth’s layers interacting in order to form igneous rock?

dmitriy555 [2]

Answer:

At convergent point of plate boundaries, sedimentary rock that is present at ocean floor is pushed down into mantle. Due to the continuous movement of rock into the mantle increase the crust the temperature. Thus after continuous rise of temperature, crust melts down and eventually rise to surface of earth in the form of volcanic eruption. and after cools down gives rise to formation of igneous rock.

Explanation:

Process of igneous rock is given below

You are at 35 N and 175 W; you move to a new location which is 40 south and 60 west of your present position. What are the coord

evablogger [386]

Answer:

The new coordinates are 5S and 125E

Explanation:

Addition of latitudes:

If they are in the same direction, you just have to add the values.

For example, 5N + 10N = 15N.

You have to be careful that we don't have any latitude higher than 90. So, if the result of your sum is higher than 90, we subtract 180 by the result, and the position is in the other hemisphere.

For example

60N + 40N = 100N

100N is larger than 90, so not possible

Subtracting and changing hemisphere

180 - 100N = 80S

When they are in opposite directions, you can just say that one hemisphere is the positive one, and the other is the negative.

In this problem, i am going to say that the North hemisphere is the positive one and the South the negative.

So, currently at 35N moving 40S. The new position is

$P = 35 - 40 = -5$

Since the result is negative, this just means that we are in the Southern Hemisphere, so 5S

Adittion of Longitudes:

They work just like the latitudes, the difference is that we don't have any longitude higher than 180. So, if we have a result higher than 180, we subtract 360 by this value and change the hemisphere.

In this problem.

175W + 60W = 235, higher than 180, so:

360 - 235 = 125E

the average of two number is 55 to subtract from the greater number ratio between number become 1:2 the smaller number is

Thepotemich [5.8K]

Complete question:

The average of two number is 55. If 2 is subtracted from the greater number, the ratio between the numbers become 1:2 . The smaller number is

Answer:

The smaller number is 36

Explanation:

let the smaller number = x

let the greater number = y

$\frac{x + y}{2} = 55\\\\$

x + y = 110

y = 110 - x --------- equation (i)

$\frac{x}{y-2} = \frac{1}{2}\\\\ y-2 = 2x\\\\y = 2x + 2 ------equation(ii)$

Substitute y in equation (ii)

110 - x = 2x + 2

110 - 2 = 2x + x

108 = 3x

x = 108 / 3

x = 36

Therefore, the smaller number is 36
