TRANSFORM BOUNDARIES: B. Strike-Slip

Explanation:

A reverse fault happens at convergent boundaries.

A normal fault happens at divergent boundaries

Hope this helps :)

The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.

"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.

Hence, option B is correct.

Answer:

1.) extreme temperature change

2.) living things in that ecosystem.

3.)the smaller herbivore population will decrease.

4.) the loss of a river system due to contamination.

5.) die out in the area.

Explanation:

Just took the QC

What can be considered as an extreme disturbance to any ecosystem is :extreme temperature change.

Whenever, there is a disturbance in terms of fire or toxic chemicals to ecosystem, then : living things in that ecosystem.

In a case, whereby no one hunt deer, then there would be decrease in smaller herbivore population.

loss of a river system due to contamination can be considered as a of a severe disruption to an ecosystem.

When there is  irreversibility destroying of ecosystem, then :species unable to travel or adapt will die out in the area.

We have that Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

From the question we are told

How many moles are present in 10, 0 grams of sodium hydroxide (NaOH )

Generally the equation for the  Molar mass of sodium hydroxide is

[tex](NaOH) = (22.990 + 15.9994 + 1.008) \\\\ {(NaOH)} = 40 g/mol[/tex]

Where

Mass_{NaOH}taken = 10 g.

[tex]Moles\ NaOH =\frac{(mass of NaOH taken)}{(molar mass of NaOH)}\\\\Moles\ NaOH = \frac{10}{(40}\\\\Moles\ NaOH =0.25moles[/tex]

Therefore

Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

The statement that describes how the atmosphere gains energy by convection is :  Air warmed by ground rises ( A )

The rising warm air from the ground into the atmosphere explains the exchange of heat energy from the ground into the atmosphere through convection and this possible due the variation in density and temperature of the ground air and the atmospheric air.

Convection is the transfer of heat energy through the movement of a medium such as air or water from one region to another. convection can occur as :

Magma come out of volcanoes that cools down and later on hardens up into rocks.  

Explanation:

Magma come out of volcanoes that cools down and later on hardens up into rocks.

The existence of magma is essential to comprehending the geology and morphology of the mantle because the majority of the mantle and crust are solid.

Different types of magma form as a result of variations in the mantle's and crust's structural features, pressure, and temperature. Decompression Melting The mainly solid mantle of the Earth moves higher during decompression melting.

Convection causes this hot material to rise to a place with lower pressure.

Therefore, Magma come out of volcanoes that cools down and later on hardens up into rocks.
