Answer:
Scientists can use the wobble to work the planet's mass and the distance from the star.
Explanation:
Detecting a star's wobble is one way to find out if there are planets orbiting it, this happens because the planet is “tugging” on it, the gravitational force from the star acts to keep the planet in orbit, and the gravitational force from the planet acts to move the star as the planet orbits. Scientists can use the wobble to work the planet's mass and the distance from the star.
Considering this information we can conclude that the correct answer is distance to the planet and mass of the planet.
I hope you find this information useful and interesting! Good luck!
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.
The answer is C. the mobile.
The physical map shows the landforms and bodies of water in specific areas on Earth's surface, the political map hows features humans have created such as the boundaries between states, provinces, territories, and countries. The topographic map shows land elevations. However all of them represent Earth's surface on different way.
