how does time affect the physical weathering of a rock?
A- rock weathers the most when first exposed, then more slowly
B- the longer the rock has been exposed, the more it has weathered
C- over time, the rock will become flat, slowing the rate of physical weathering
D- time does not affect physical weathering, only chemical weathering
Answer:
D
Explanation:
Time can't do much to a rock, but chemical weathering is more effective
The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.
What is the sedimentary rocks?Sedimentary rocks are near the surface so the only one that works for that is sedimentary rocks are formed with water too, it weathers away at the rocks to form little sediments and metamorphic rocks are in the earths interior and sedimentary are at the exterior, metamorphic rocks are formed through extreme heat and pressure meaning its near the earths interior.
Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.
Therefore, The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.

Which might be considered a limiting factor to the amount fish in a lake *
A)Amount of squirrels in the environment
B)Amount of water in the lake
C)Temperature of the lake
D)Choice 2 and 3
Answer:
D). Choice 2 and 3
Explanation:
Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"
This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.
Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.

Why would an enzyme that is effective with one reaction have no effect on another reaction?
Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.Answer:
