In which way are glaciers and rivers similar?
A. Both are made of solid water.
B. Both have quickly flowing water.
C. Both transport and deposit material.
D. Both can move large boulders hundreds of miles.
Answer:
c
Explanation:
they both deposit and transport material.
The way by which glaciers and rivers similar are both have quickly flowing water. Thus, option B is correct.
Both glaciers and rivers are natural water systems that play a significant role in the movement and transportation of materials. While glaciers are large masses of ice that flow slowly over land, rivers are bodies of flowing water.
Glaciers and rivers both transport materials from one location to another. Glaciers carry rock debris, soil, and sediment within their icy mass as they move downhill, while rivers carry sediments such as sand, silt, and rocks downstream.
Both glaciers and rivers have the ability to erode the land and transport the eroded materials. Glaciers can scrape and pluck rocks and sediments as they move, causing erosion of the underlying landscape. Similarly, rivers erode the bed and banks of their channels, carrying away loose materials in the process.
Therefore, the correct answer is C. Both glaciers and rivers transport and deposit material.

what is the density to the nearest hundredths, of a metal with a volume of 3.00 cm3 and a mass of 8.13g?
The density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³. Details about density can be found below.
How to calculate density?The density of a substance is a measure of the mass of matter contained by a unit volume and it can be calculated by dividing the mass of the substance by its volume.
According to this question, a metal with a volume of 3.00 cm³ and a mass of 8.13g is given. The density of the metal can be calculated as follows:
Density = 8.13g ÷ 3cm³
Density = 2.71g/cm³
Therefore, the density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³.

Answer:
i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.
ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.
Explanation:
Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.
For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.
In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.
In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.
In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.
In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.
