Which example provides scientific data about the earth's interior?
a.
the motion of continents
b.
earth's orbit around the sun
c.
how seismic waves travel
d.
the size of volcanoes on the earth’s surface

The correct answer is C. How seismic waves travel

Explanation:

The Earth is composed of different layers that include the crust, the mantle, the outer core and the inner core, each of these layers and the features of them have been discovered throughout the years by topographers, and other experts mainly by studying seismic waves. This can be explained as seismic waves that occur due to earthquakes, eruptions, explosions and other phenomena, travel through the different layers of Earth and depending on which layer they are they display different features and speed which is the main information scientists used to determine the layers of Earth and other features of Earth's interior. Thus, it is how seismic waves travel the one that provides scientific data about the earth's interior.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
