Question
Moraines are caused by ____________. a. water c. acid rain b. wind d. glaciers
Solution 1
Moraines are parallel ridges of debris deposited along the sides of a glacier. The unconsolidated debris can be deposited on top of the glacier by frost shattering of the valley walls and/or from tributary streams flowing into the valley.

Moraines are caused byÂ D. GLACIERS
Solution 2
Moraines occur through a geomorphological process during a moving glacier. Basically, the glacier motion picks up debris such as rocks, sediments, etc. and deposits them, thus creating moraines. So, your correct choice is D. GLACIERS.Â

Question
How freely water moves into and through soil or rock is called _____. porosity permeability tributary saturation
Solution 1

How freely water moves into and through soil or rock is called permeability. It is true that water will always look for holes in places where it could get in to since it is its nature to be free moving.Â  Permeability, by definition is allowing liquids or gases to pass through

Solution 2

The correct answer is - permeability.

The permeability is the substance's ability to allow another substance pass through it, which in this case would be the water through the rocks.

The unit used for the measuring of the permeability is milidarcies, at least most of the time.

The permeability is directly connected to the porosity of a rock. The more porous a rock is, the bigger the permeability, and the less porous a rock is, the lesser the permeability.

Through this process, the water is able to penetrate deep inside the rocks and into the ground. That results in the creation of water reservoirs from which the springs emerge when they are full and the water is able to come to the surface, or reservoirs of groundwater.

Question
Surface currents are caused by friction between which two elements? a. the ocean surface and wind b. warm air fronts and cold air fronts c. the ocean surface and deep ocean waters d. northern currents and southern currents
Solution 1
A.) The ocean surface and wind

Surface currents are caused by friction between the ocean surface and wind.

Ocean current is the horizontal movement of seawater on the ocean's surface. It is driven by the wind's circulation above the ocean'sÂ surface. Frictional stress found between the ocean's surface and the circulating wind causes the water to move at the direction of the wind.Â Â
Question
In most of Southeast Asia,the soil is poor.What causes the soil in the same areas to be ricker and more productive? With mostly poor soil why does plant growth remain strong throughout most Southeast Asia?
Solution 1
Most of the soil used for agriculture in Southeast Asia is a soil that was once part of a dense tropical forest. This soils are very rich in nutrients, but they weather very fast as well when the forest is cleaned out and they are on an open space, so they are fertile for just few years. In the same area we also have soils that are rich and fertile all the time, these soils are along the banks of the bigger rivers. This rivers flood their surrounding areas every year so enrich the soil, thus making it a fertile alluvial soil.Plant growth still remains strong because there are enough alluvial soils, but most importantly most of the plants that are grown here do not require rich soils to grow and prosper.
Question
We usually get about 10 inches of rain a year. It's raining right now." The first statement is about _____ and the second statement is about _____. climate, weather weather, climate
Solution 1

The answer is: 1.- Climate, and 2.- Weather.

Explanation:

Climate generally refers to what usually happens over a measure of time, for example a year.

Weather, is a weather forecast by cities for today, tomorrow and the next days.

The answer is: 1.- Climate, and 2.- Weather.

Solution 2
The first statement is about CLIMATE and the second is about WEATHER.
Question
Why did scientists not know the 1989 San Francisco earthquake was coming?
Solution 1
It's the simplest reason really, because the earthquakes can not be predicted. Talking about a short term prediction, yes, some occurrences give heads up that an earthquake is coming, though it is never a sure thing, but speaking long term, no earthquake can be predicted. Scientists know which are the places where earthquakes will most likely appear, but very often they are up to a surprise.
Question

Solution 1

"An animal's behavior is based on its instincts." Is a statement most likely coming from an ethologist. Ethology by definition is the scientific and objective study of animal behavior especially under natural conditions alongside its formation and evolution.

Question
________ has a large percentage of voids and is lightweight, so therefore has the ability to float in water.
Solution 1
Sponges are very lightweight, they have large percentage of voids as well, this practically means that they have low density structure. Their density is smaller than the density of the water, so this means that it will float on the water instead of sinking.Â
Solution 2

Pumice stone has a large percentage of voids and is lightweight, so therefore, has the ability to float in water.

Explanation:

• Pumice is one unique type of volcanic rock which resembles a sponge that is artificially made.
• It is made up of volcanic glass and contains a number of voids which act like small packets of air allowing the stone to float on water.
• Its composition makes it light in weight and also mostly light in color.
