1. Where are hurricanes most likely to form?
a Over warm tropical waters
b Over frozen Arctic Waters
c Over a tropical rainforest
d Over cool Atlantic Waters
Answer:
Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. The generic, scientific term for these storms, wherever they occur, is tropical cyclone.

where are the oldest stars on the hr diagram????
Answer: The oldest stars are found on the top right on the HR diagram. Hope this helps!
The oldest stars on the Hertzsprung-Russell (HR) diagram are located in the lower-right region known as the main sequence turnoff, the stars in the universe can se seen and studied in several ways.
The main sequence turnoff represents the point where stars begin to leave the main sequence and enter different stages of evolution. The position of the turnoff depends on the age of the stellar population being observed. Older stellar populations, such as globular clusters or the halo stars of a galaxy, have turnoffs located at lower luminosities and cooler temperatures.

Metal atoms loss electrons while non Metal atoms gain electrons .
When atoms form ions, they usually loose or gain enough electrons to achieve the electronic configuration of a noble gas. Metal atoms loose electrons while nonmetal atoms gain electrons.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Why does the rate of dissolution for a gas decrease as the temperature of a solvent increases?
more space for the solute to escape
less space for the solute molecules
less space between solvent molecules
more collisions between solute and solvent molecules
Answer:
As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return back to the gas phase. As a result, the solubility of a gas decreases as the temperature increases.

Students were asked to describe evidence of Plate Tectonic Theory. Their answers are listed
below.
Student 1: The shape of the continents suggests that they were once connected together.
Student 2: Similar fossils and rock formations have been found across different continents
providing evidence that they were once connected.
Student 3: Glacial evidence indicates that different
continents were once connected near the
South Pole.
Student 4: Magnetic rocks indicate that the sea floor has been growing and spreading over
time.
Which student(s) descriptions listed above accurately describe evidence supporting Plate
Tectonic Theory?
Answer:
One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.
Explanation:
Students were asked to describe evidence of Plate Tectonic Theory.
descriptions listed above accurately describe evidence supporting Plate
Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."
What is plate Tectonic Theory?
The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.
What is the South Pole?The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.
The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.
