Challenges for growing crops are you don't know if it will be successful, you have to have enough water, the dirt has to be fertile, and the weather may affect how the plant grows.

Growing crops can be difficult because of floods drowning the plants, tornadoes ripping the field apart, and other kinds of storms that can damage the plants. Also, many plants need to be watered on a daily or weekly basis, making it difficult to do other things if you own a large field with many crops that need to be watered.

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

Stolb23 [73]

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.

A Sense of Proportion: Earth orbits 1 AU from the Sun, and the Oort Cloud extends from about 10,000 to 100,000 AU from the Sun.

zysi [14]

Answer: 6.313 miles

Explanation:

The distance is calculated by Simple Rule of Three:

$x = \frac{100000 AU}{1 AU}\cdot 4 in \cdot (\frac{1 mi}{63360 in}) \\x = 6.313 mi$
