Warm water rises because it is ............ than cool water.
a) warmer
b) cooler
c) more dense
d) less dense
**Answer and I will give you brainiliest**
Answer:
I'm pretty sure the answer is D.) Less Dense
Explanation:
Answer:
d) less dense
Explanation:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
what plate movements and earth features lead to the Earth Quake Prince William sound? (the Alaska Earthquake)
According to "M9.2 Alaska Earthquake and Tsunami of March 27, 1964",
On March 27, 1964 at 5:36pm local time (March 28 at 3:36 UTC) an earthquake of magnitude 9.2 occurred in the Prince William Sound region of Alaska. The earthquake rupture started approximately 25 km beneath the surface, with its epicenter about 6 miles (10 km) east of the mouth of College Fiord, 56 miles (90 km) west of Valdez and 75 miles (120 km) east of Anchorage. The earthquake lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the M9.5 earthquake in Chile in 1960.
The map shows the epicenter of the 1964 Alaska Earthquake (red star), caused when the Pacific Plate lurched northward underneath the North American Plate.

Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

Under what circumstances would molecular motion stop?
Answer:
All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius.
Explanation:
It is based on molecular motion, with the temperature of 0K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15K, while the boiling point is 373.15K

Which of the following factors are responsible for the annual rise and fall in carbon dioxide levels? (Several choices may be correct.)
A) fallen leaves decaying in autumn
B) consumption of more fossil fuels in the winter
C) plant growth in the spring
D) increase in surface temperature of the earth during summer
PS: I've tried A & D and B & D (they were both wrong)
I believe the answer is
A & C.
Following factors are responsible:-
Fallen leaves decaying in autumn.Plant growth in the springWhat is the reason for carbon dioxide rise in environment?Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over many millions of years.What are the consequences of rise in carbon dioxide?Transpiration is affected by the degree of ground cover.Rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration.Rising carbon dioxide concentrations will decrease leaf stomata. conductance to water vapor.

(PLEASE HELP IF U CAN , 50 POINTS : NEED IT BY 11:59)
Answer:
Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.
Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.
Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".

What is the connection between the liquid state of water and hydrogen bonding?
Answer:
In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. When water is cooled, the molecules begin to slow down. Eventually, when water is frozen to ice, the hydrogen bonds become permanent and form a very specific network.
Explanation:
How are atoms, elements, and compounds related?

Atoms join together to form elements, elements join together to form compounds.

Animals such as foxes and cats often prey on rabbits. Based on the growth curve of the rabbit population, what
might have happened if a group of predators moved into the rabbits habitat during the tenth generation and
began eating the rabbits?
Answer:
If this happened that would affect to amount of food the other predators got, eventually causing decreases in their species.
Explanation:
If a group of predators moved into the rabbit's habitat during the tenth generation and began eating the rabbits, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit's population.
What is a Habitat?A habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In this natural environment, the basic demands of an organism are fulfilled like food, space, mating partner, etc.
When a group of predators starts eating the rabbits, the population of rabbits gradually decreases. Due to this, the other predators of the same species feel the scarcity of food and resources. As a result of this, their number or population also declines slowly or adapted to other species.
Therefore, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit population.

Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
