Why did scientists FIRST hypothesize that a meteorite impact caused the extinction at the K-Pg Boundary?

Answer:

They found evidence of an impact crater in Mexico

Explanation:

The K-Pg boundary is the boundary that separates two periods, but also two eras. The two periods that are separated by this boundary are the Cretaceous and the Tertiary, while the two eras are the Mesozoic and the Cenozoic. The boundary is marked by a mass extinction, and the scientists started to hypothesize as to why it happened. There were numerous different theories, but a clue in Mexico, or rather right next to the Yucatan Peninsula, shed new light on it. The scientists found an impact crater, formed either by a large asteroid or a comet. Such an impact would have easily caused sudden and drastic changes on the Earth, killing of the majority of the species. This impact released such a big amount of energy that it killed everything in the surrounding area in seconds. On top of that, it caused an extremely hot wave of air across the whole planet, killing many more organisms. It managed to trigger most of the volcanoes to erupt, as well as the earthquakes, causing also very large tsunamis. The sunlight got blocked for quite some time from all the aerosols in the atmosphere as well. This resulted in a mass extinction of the dominant species, like the dinosaurs, but it opened up the terrain for the evolution of the others, like the mammals.

Lilit [14]

Answer is give below

Explanation:

when any object or spacecraft is located exactly between Earth and Mars.

than Earth gravitational force will be exerted on spacecraft more than the Mars gravitational force.

as we know that gravity on the Mars is less than the gravity on the Earth

so spacecraft will move very slowly toward the Earth.

gravity force on Earth =  9.807 m/s²

gravity force on Mars =   3.711 m/s²

Cultural convergence occurs more rapidly with improved transportation.

<h3>What is cultural convergence?</h3>

Cultural convergence is the phrase used to describe how civilizations tend to alter and adapt when they are frequently exposed to different cultures. Cultures will become more similar the more they interact with one another. Time and points of interaction are two major aspects that affect cultural convergence. Greater commonalities between cultures emerge from longer exposure times, of course. Increased contact rates, accessibility to communication and transportation, and membership in the same groups all speed up the rate of convergence. It will take longer for a civilization to absorb the traditions of another culture if they are just sometimes exposed to it through pop culture media than if they are exposed to their food, language, art, etc.

OlgaM077 [116]

Answer:

The essential element of geography called physical systems focuses on the study of the Earth’s natural environments and the systems that shape them.

<em>Physical geography studies the layers of the Earth and the connection between them. For example, the interaction between the anthroposphere and the biosphere - the way in which the protection of natural environments is achieved, but in which tourist routes, tourist activities are also integrated.</em>

What role does photosynthesis have in the cycling of matter into and out organsms
djverab [1.8K]

Answer:

Photosynthesis play important role in the cycling of matter into and out of the organisms as photosynthesis is the process in which plants utilize carbon dioxide (CO2) and water (H2O) and releases oxygen (O2) and energy in the form of carbohydrate or sugar. Other organisms utilizes these oxygen and energy or carbohydrate for the chemical reaction in their body.

So, photosynthesis take carbon dioxide (CO2) and water (H2O)  from outside as input and gives oxygen (O2) and energy as output.
