Answer:continental and oceanic crust

Explanation:continental crust is the oldest part of the earth because it is not very active in terms of growing in size the continental crust is approximatly 4.4 billion years old then the moon was newly formed. oceanic crust is constantly renewing itself through divergent boundreis that means the crust is moving apart from one another, the oceanic crust is approximatly 260 million years old but thats the parts farthest away from any fault lines the ones parts choses to the oceanic boundreis are approximatly 200 million in terms of rock this is young compared to the oldest rock which is around 4 billion years old

harina [27]

Human activities such as mining, pollution, minerals processing, landfills, etc have an effect on the flow pattern.

<h3>Effect of pollution</h3>

It should be noted that pollution is usually difficult to control because it is often the result of human infrastructure around a river.

For example, sewage and effluent are discharged into rivers in some areas and this can lower the pH of the water, and hence affect the organisms.

Also, human activities such as mining, pollution, minerals processing, landfills, impact negatively on the quality of water and the flow pattern in the upper reaches of the blood river in Limpopo.

sleet_krkn [62]

Answer:

The correct answer is: a) it relies on testimony from people.

Explanation:

The Mercalli intensity scale, unlike the Richter scale, does not directly measure the energy of an earthquake. Rather, it takes into account the damage and effects that the earthquake caused. When there is little damage, it relies on the testimony of people who felt the earthquake, which may vary and is ultimately subjective to people's perception.

The Mercalli Intensity Scale ranges from "Not felt" to "Catastrophic" going through 12 scale intensities.

Question 5(Multiple Choice Worth 3 points) (02.01 MC) Wegener's theory of continental drift was formulated at a time when eviden
Sergio039 [100]

The correct answer is - Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement.

Harry Hess is one of the people that is most important when it comes to the proving and world wide acceptance of the continental drift theory.

Hess was very interested in the topic, and he was constantly looking for clues that would bring light to it and finally have a definite proof of it. While sailing through the Atlantic and doing some examinations, Hess noticed that there high mountains in the water, having flat peaks, and being arranged in an interesting manner. These underwater mountains, named guyouts, were the highest at a certain point, and than on both sides, as the distance was increasing they were becoming smaller and smaller.

What Hess stumbled upon was the seafloor spreading and how it works, and he recognized that quickly. He immediately went on to share what he discovered, that there's magma coming from bellow, solidifying and spreading, thus creating new crust while pushing the old crust away from the center, which is the reason why the continents are moving.
