Explain how cross cutting principles (intrusions, inclusions, faults) help to determine the relative age of a rock layer.

Answers

Answer:

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. ... So the fault must be the youngest formation that is seen. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers

false

Explanation:

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.

Sb2O3 + 3 C --> 2 Sb + 3 CO

40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO

Answers

Answer: 40.3 L

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]

[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]

According to stoichiometry :

1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]

Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex] of [tex]CO[/tex]

Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]

Thus 40.3 L of CO is produced.

What is responsible for the blue sky?

Answers

Answer:

The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.

Explanation:

Answer:

sun shine

Explanation:

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.

Answers

Answer:

The sound is transmitted through water until it reaches the other whale.

Explanation:

When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.

The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.

How sound may transmit from one place to another?

The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.

In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.

It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.

Therefore, the correct option for this question is A.

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?

- 20 mL
- 259 mL
- 25 mL
- 50 mL

Answers

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

How much money has Sherry raised so far?A) $10B) $20C) $30D) $40 Polina the Polar Bear sat on an ice floe in the Arctic Ocean, north of Alaska. Polina was waiting for her mother, Bearnice, to return hwith some tasty seal blubber for lunch. Bearnice was hunting, waiting for seals to come up for air through holes in the ice, the same way Polar Bears have hunted in the winter for centuries. Except this year there was one big difference.A lot more of the ice had melted last summer, and this winter it hadnt refrozen as usual. A combination of warmer weather and changes in water and air currents was making the ocean warmer than anyone could remember, and Bearnice had to swim farther every day to find a good hunting spot.As Polina waited for her mother to bring food back to her floe, the ice shrank bit by bit until she was sitting on very thin ice. As Polina waited helplessly, the furry white cub heard a deep voice coming from the direction of the sea.Hellooo little bear, it said. Polina had never heard such a deep voice. She lifted her tired head to look out over the water, and was surprised that the voice seemed to come from a dark ice floe just offshore."No, wait!" It had a huge eyeball that was looking directly at her. It wasnt an ice floe it was the largest whale Polina had ever seen. It was also the first whale that had ever spoken to her.They call me Farswimmer,said the whale, because I travel all over the world, having adventures and learning new things. What brings you here alone, Polar Bear? Farswimmer was very old, and he had seen many changes in his years of exploring the oceans. He certainly knew more about the world than most polar bears. Farswimmer seemed like a nice whale, but Polina remembered Bearnice, her mother, and how she hadnt come back from hunting.Farswimmer blew a tall spout to distract Polina and stop her from crying.When Polina told the whale her own story, he said, Im headed north anyway. You could ride on my back, and we can look for your mother. Are you ready for an adventure? The next morning, Farswimmer and Polina charted their course and took off. Polina rode Farswimmers back and sometimes floated behind him, holding his tail. She also stood on his back and pretended she was surfing. It was a blast.They took a break on an ice floe. Soon, they saw something in the distance that looked like another ice floe, but just to be sure, Farswimmer left Polina on the ice and swam to the floating object.It wasnt an object. It was an animal. Farswimmer used his fat nose to push the animal to Polinas icy raft. When they got closer, Polina saw a familiar face.Mommy, she yelped. Bearnice was very tired, but the sound of her cubs voice made her happy. She opened her arms and the two embraced each other in a big bear hug.Read the passage on the left to answer the following questions:1) What is the main conflict in this story?A) Farswimmer cannot find Polina's mother. B) Polina's mother is unable to find any seals to feed Polina. C) Bearnice decides that she wants to let her daughter live alone. D) The ice is melting around Polina, and her mother hasn't returned. 2) Which statement best describes the relationship Polina the Polar Bear and the whale Farswimmer?A) Polina is angry at Farswimmer for being so large and scary. B) Farswimmer has no interest in helping Polina find her mother. C) The whale Farswimmer is kind and helpful to frightened Polina. D) Polina is in love with Farswimmer the whale and wants to run away with her. 3) How is Farswimmer characterized in this story?A) as an unhappy and mean whale B) as a kind and wise old whale C) as an indifferent, cruel creature D) as a simple-minded, innocent creature 4) Which BEST describes the characters in this story?A) Farswimmer is old and Polina is young.
