Why do not all rock types contain fossils?
Excessive heat and pressure can destroy fossils.
Fossils can only be created in certain places around the world.
Fossils cannot be created near volcanoes.
Fossils are too large to be found in igneous and metamorphic rocks.
Answers
Answer:
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.

A valley or depression between continents
A. Ocean Ocean basin.
B. Divergent boundary
C. Transform boundary.
D. Convergent boundary
Answers
A valley or depression between continents is called Ocean basin. Therefore, the correct option is option A.
What is valley?A valley is indeed a long, low region that commonly runs between mountains or hills and has a river and stream that runs through one end to another. Most valleys are produced through long-term erosion of the ground surface by streams or rivers. Some valleys are produced by glacial ice erosion.
These glaciers may persist in valleys in mountainous areas or in polar regions. These glacially produced valleys could have been constructed or extended during ice periods at lower latitudes or elevations, but they are currently ice-free and populated by rivers or streams. A valley or depression between continents is called Ocean basin.
Therefore, the correct option is option A.

What will be the volume occupied by 100 grams of oxygen gas
at STP?
Answers
Answer:70L
Explanation:
The volume occupied by 100g of oxygen gas at STP is 70L.
1 mole of a gas at STP occupies 22.4 L volume.
The same goes for oxygen gas, [tex]O_2[/tex]. 1 mole of [tex]O_2[/tex] occupies 22.4L volume.
Now the molar mass of [tex]O_2[/tex] is = 32g
So the number of moles of [tex]O_2[/tex] in 100g is
n = 100/32
n = 3.125 moles
Volume occupied by 3.125 moles or 100g of [tex]O_2[/tex] is
V = 3.125 × 22.4 L
V = 70 L volume is occupied by 100g of oxygen gas.

If 36 of the compound decomposes in 60 minutes, the half-life of the compound is ________minutes. -5 93 41 -18 39
Answers
Answer: The half-life of the compound is 93 minutes
Explanation:
Expression for rate law for first order kinetics is given by:
[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant =100
a - x = amount left after decay process = (100-36) = 64
a) for completion of 36 % of reaction
[tex]60=\frac{2.303}{k}\log\frac{100}{100-36}[/tex]
[tex]k=\frac{2.303}{60}\log\frac{100}{64}[/tex]
[tex]k=0.0074min^{-1}[/tex]
b) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
[tex]t_{\frac{1}{2}}=\frac{0.693}{k}[/tex]
[tex]t_{\frac{1}{2}}=\frac{0.693}{0.0074min^{-1}}=93min[/tex]
The half-life of the compound is 93 minutes
