What are natural causes of earthquakes that is what are the tectonic features and actions that result in seismic waves?
oksian1 [2.3K]
Anearthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault.
or

An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves.

Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph.

The magnitude of an earthquake is conventionally reported using the Richter scale or a related Moment scale 





An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground.

The strain becomes so great that rocks give way by breaking and sliding along fault planes.

Earthquakes may occur naturally or as a result of human activities.

Smaller earthquakes can also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments.

Explain how the organisms in this forest biome adapt to their environment. Also explain how the parts of the biome work together
raketka [301]

Answer:

In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.

I did the tutorial on edmentum.

A pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. Round pea sha
krok68 [10]

Answer:

1 out of 16 or 1/16

Explanation:

Let:

R = Round seed      r = wrinkled seed

Y = Yellow seed     y = green seed

Starting from the parent generation or the P generation, the genotype of the parents would be:

RRYY x rryy

This is because the cross is between a parents that are "purebred" for specific traits. This means that the parents are homozygous for the traits which in genotype form is represented by either two capital letters or two lower case letters.

Attached is the F1 generation results between a cross between the P generation.

As you can see the genotype of all the offsprings is RrYy.

Now also below is the cross between the F1 generation offsprings.

For recessive traits, it is only expressed when the dominant gene is not in the genotype, or in other words, the genotype is all in small letters. Since we are looking at two traits, you need to look for how many squares out of the total have all lowercase letters.

There is only 1 rryy out of the 16 predictions. So the answer would be 1/16.

Laura pushes on the pedals of her bike
Lelu [443]

Answer: 2

Explanation:- Mechanical advantage is the ratio of the output force to the input force.

Mechanical advantage=\frac{\text {output force}}{\text {input force}}

Given:

Input force = 320 N

output force= 640 N

{\text {Mechanical advantage}}=\frac{640N}{320N}=2
