When ice cubes cause weathering, what type of weathering is it called?
Answer:
Chemical Weathering
Explanation:
Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals. These minerals are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

Brian's family has a compost pile at home. They put all the weeds they pull up from the garden in it as well as any vegetable waste they gather from the kitchen. If they keep it moist, all this vegetation will
eventually turn into organic soil by the chemical process of decay. Since decay involves a variety of chemical reactions, how might temperature affect the rate at which the compost turns into sol?
Temperatures near freezing would make it speed up.
It would happen faster at warmer air temperatures.
Changing temperatures would not affect the chemical reactions.
Warm summer air temperatures would make it slow down.
Answer:
Option - It would happen faster at warmer air temperatures
Explanation:
The chemical process of converting organic matter such as plants, litter into organic soil, or organic compost called decomposition and perform by decomposers such as fungus or bacteria.
Like all other living organisms, decomposers also live in an optimal range of temperature. The major decomposers normally lie in the range of 30 to 40-degree celsius. Any type of fluctuation in this range might slow down the reaction of decomposition.

Which statement best describes why radioactive atoms can be used to date materials?
A.
Nonradioactive atoms in rocks eventually turn into radioactive atoms.
B.
The Sun interacting with atoms in a rock causes new atoms to form over time.
C.
The ratio of radioactive atoms to other kinds of atoms changes over time.
D.
The number of radioactive atoms in a substance increases over many years.
The ratio of radioactive atoms to other kinds of atoms changes over time. Hence, option C is correct.
What is radioactive decay?In the process of radioactive decay the unstable atom nuclei of the parent nucleus break down and split so as to release the daughter atoms or nuclei along with the release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of the daughter atom increases.
Radioactive atoms can be used to date materials because the radioactive decay occurs at a known rate, and the density of fission tracks for the amount of uranium within a mineral grain can be used to determine its age.
Hence, option C is correct.

what did rutherford's gold foil experiment tell about the atom
Answer:
The alpha particles that were fired at the gold foil were positively charged. ... These experiments led Rutherford to describe the atom as containing mostly empty space, with a very small, dense, positively charged nucleus at the center, which contained most of the mass of the atom, with the electrons orbiting the nucleus.

B. It forms inside the earth.
C. It is made from sediments.
D. It has a fine-grained texture.
Answer:
B
Explanation:
I believe because intrusive stays within the earth
The accurate statement regarding the intrusive igneous rock is that It forms inside the earth.Hence, Option (B) is correct.
What are Intrusive igneous rock ?Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.
The magma cools very slowly over many thousands or millions of years until is solidifies.

How are protons and neutrons the same and how are they different?
Explanation:
Protons, Neutrons and Electrons are the three primary subatomic particles that form an atom.
Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge.
Together the protons and Neutrons make up the mass of the atom.
Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.

A sample of helium gas at a pressure of 0.538 atm and a temperature of 256 °C, occupies a volume of 437 mL. If the gas is cooled at constant pressure until its volume is 316 mL, the temperature of the gas sample will be
Answer:
110 °C
Explanation:
The following data were obtained from the question:
Initial pressure (P1) = 0.538 atm
Initial temperature (T1) = 256 °C
Initial volume (V1) = 437 mL.
Final pressure (P2) = constant = 0.538 atm
Final volume (V2) = 316 mL
Final temperature (T2) =?
Next we shall convert 256 °C to Kelvin temperature. This Can be obtained as follow:
T(K) = T(°C) + 273
Initial temperature (T1) = 256 °C
Initial temperature (T1) = 256 °C + 273 = 529 K
Next, we shall determine the new temperature of the gas as illustrated below:
Pressure = constant
Initial temperature (T1) = 529 K
Initial volume (V1) = 437 mL.
Final volume (V2) = 316 mL
Final temperature (T2) =?
Applying the Charles' law equation, we have:
V1 /T1 = V2 /T2
437/529 = 316/T2
Cross multiply
437 × T2 = 529 × 316
437 × T2 = 167164
Divide both side by 437
T2 = 167164 / 437
T2 = 382.5 ≈ 383 K
Finally, we shall convert 383 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 383 K
T(°C) = 383 – 273
T(°C) = 110 °C
Therefore, the new temperature of the gas is 110 °C
