Answer:
Ripple marks are caused by water flowing over loose sediment which creates bed forms by moving sediment with the flow. Bed forms are linked to flow velocity and sediment size, whereas ripples are characteristic of shallow water deposition and can also be caused by wind blowing over the surface.

Your family just moved into a new house. There are three rooms available for you, your brother and sister, but one is larger than the others and has a bigger closet. Your sister has the most clothes and insists she needs the room. Your brother thinks he should get the room because he’s the oldest. You want the extra space for your drum set. It bothered everyone when you practiced in the dining room. Your parents told you to work it out amongst yourselves.
Conflict Scenario:_____________________________________________
Why?
here are the choices
Competition
Avoidance
Accommodation
Compromise
Collaboration
Answer:
Competition/collaborate most likely collaboration
Explanation:
Trust me on this this will be the best and least messy way to handle the problem, first try to see if your sister can give away some of her clothes, does your brother really need the room, and can you find a different place to store your drum set if not, competition. Decide a fair competition, something that no one is better at than the other, decide the rules, no cheating, and whatever the out come try to be mature about it, maybe your parents will reward you and your siblings.

Which of the following shows two vehicles with equal velocities? A- two identical cars traveling at the same speed in different directions. B- two identical cars traveling at different speeds in the same direction. C- a car and a motorcycle traveling at the same speed in opposite directions. D- a car and a motorcycle traveling at the same speed in the same direction
A car and a motorcycle traveling at the same speed in the same direction have the same velocity.
Velocity is the time rate of change in displacement. It is given by:
Velocity = displacement / time
Velocity is a vector quantity, hence it has both magnitude and direction.
Two vehicles are said to have the same velocity if the have the same speed and move in the same direction.

Seattle, Washington and Bismarck, North Dakota experience very different temperatures even though they are at the same latitude. The air temperatures are affected by their surroundings! Which city would be hotter during the day: Bismarck or Seattle? Why?
Answer:
BELOW
Explanation:
Seattle (near water) would have hotter temperatures because it is by a large body of water. Unlike Bismarck which is surrounded by land. Bismarck would get hotter. Seattle would be affected the large body of water which heats more slowly than the continent warming.
Why do you see objects when you shine a flashlight in a dark room?
Answer:

The law of superposition allows geologists to determine _______ timelines.
A.) Relative
B.) Exact
C.) Probability
D.) Coventional
Answer
b exact because The principle of fossil succession states that different types of fossil organisms.
The law of superposition allows geologists to determine relative timelines. Using superposition principle, the relative age of rocks in the earth surface can be determined.
What is super position principle?This law states that, older sedimentary rock layers are positioned below younger sedimentary rock strata according to the law of superposition. scientifically speaking, rocks and silt build up in layers throughout time, with each layer forming in temporal order.
The younger rock layers are found beneath the older rock layers, which form first. In the middle of the 1600s, Nicolaus discovered this idea after examining rock layers and concluding that geological history was obvious.
Applying this to the actual world, the oldest layer of rock would be found at the bottom of a cross-section of a mountain or deep cavern, and each successive layer above it would be younger or newer. It portrays the image of rock strata produced in stacks through the word superposition, which means to set one on top of the other.
Hence, the relative age of rocks and the period of its formation can be determined.

Question
the sun transmits energy to the earth in the form of?A. radiation
B. conduction
C. convection
EXPLANATION:C: Convection Transfer of the Sun's Energy through Earth's SystemsWhen the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.a can of soup is begin heated in a sauce pan. as the soup is heated, the warm fluid becomes less dense and rises, while the cooler part of the soup is more dense and sinks. this current of soup is an example of?.

Explain why an X-linked recessive trait is expressed more commonly in males than in females.
Answer:
X-linked recessive inheritance
A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.

Do you do more work if you go up a mountain at a steep angle versus a gradual angle?
Answer:
For an inclined plane, less force is put into moving an object up the slope than if the object were lifted straight up, so the mechanical advantage is greater than 1. The more gradual the slope of the inclined plane, the less input force is needed and the greater the mechanical advantage.
