What force makes water flow through a watershed?

Gravity is primarily responsible for causing water to flow through a watershed. As water moves downhill, it follows the path of least resistance, carving out channels and rivers as it flows. Other factors such as topography, soil permeability, and precipitation rates also influence the movement of water in a watershed.

What is a period of little rain?

A period of little rain is known as a drought. This extended period of dry weather can have serious effects on agriculture, water supply, and ecosystems.

Is the effect of grass or dirt surface on the distance a ball can roll?

Yes, the surface of grass or dirt can affect the distance a ball can roll. Grass typically offers more resistance to the ball, causing it to slow down quicker compared to rolling on dirt, which can result in less distance covered. Additionally, the condition of the surface and its firmness also play a role in how far a ball can roll.

Where is annual temperature range least?

The annual temperature range is least near the equator and in tropical regions, where temperatures remain fairly constant throughout the year. This is due to the consistent amount of sunlight and limited seasonal variation in these areas.

What pulls gas molecules in the atmosphere toward the Earth?

Gravity is the force that pulls gas molecules in the atmosphere towards the Earth. The Earth's mass creates a gravitational pull that acts on all objects, including gas molecules, causing them to be attracted towards the Earth's surface.

What are the invisible mixture of gases surrounding the earth?

The atmosphere which is made up of nitrogen (~78 percent) and oxygen (~ 21 percent) with lesser amounts of argon, carbon dioxide, hydrogen, neon, helium, and other gases.

Model of evolution showing rapid change?

A model that demonstrates rapid evolution is punctuated equilibrium. This model suggests that species experience long periods of stability (equilibrium) with sudden bursts of significant change (punctuation) that lead to new species formation. This rapid change occurs in response to environmental pressures, such as natural disasters or new competitive pressures.

What forms of carbon are common in solid earth?

Common forms of carbon in the solid Earth include diamond, graphite, and organic carbon found in rocks and sediments. Additionally, carbonates, such as calcite and dolomite, are prevalent in sedimentary rocks.

When does summer start in Georgia?

Summer anywhere in the Northern Hemisphere begins in June.

Is the core liquid or solid?

There are two parts of the core: Inner and Outer. The outer core is liquid, the inner solid. The inner core is solid due to the pressure exerted on it, despite the excessively high temperature.

Graphite is a mineral that does not leave a clear streak?

well i really don't know sorry. Here are some useful things close to that...

1. Mica shows clear cleavage.

2. Hardness is a measure of how easily a mineral can be scratched.

ill tell you as soon as possible when i figure it out! Thank you

What is a thick question?

A thick question is one that requires deep thought, reflection, and analysis to answer fully. It typically cannot be answered with a simple yes or no, but instead prompts further exploration and discussion on a particular topic. These types of questions often lead to more meaningful and insightful conversations.

Is helium easy to find?

kind of you can find it on the stars and some gas planets and a little bit on earth

What kind of fossil evidence supported wegeners hypothesis?

Fossil evidence supporting Wegener's hypothesis of continental drift included identical fossils found on separate continents, showing that these landmasses were once connected. This supported the idea that continents had drifted apart over time. Additionally, the presence of ancient glacial deposits in regions that are now too warm for glaciers to form suggested that these areas were once located closer to the South Pole.

What is hydrologic response unit?

A hydrologic response unit (HRU) is a spatial unit used to represent different hydrological processes within a watershed. It integrates various land cover, soil type, and topographic characteristics to simulate the runoff and water balance in hydrological models. HRUs help in understanding the complex interactions between land surface and hydrological response.

What is the value of a fake Dorothy ann night and day vase?

The value of a fake Dorothy Ann Night and Day vase would be significantly lower than that of an authentic vase. The value of a fake item is subjective and can vary, but generally, it would be considered a replica or inauthentic piece with little to no significant value to collectors of genuine Dorothy Ann pottery.

What information should be included in a description of a locations climate?

A description of a location's climate should include average temperature ranges, typical weather patterns (e.g., rainy season, dry season), average rainfall amounts, and any extreme weather events that are common in that area. Additionally, information on humidity levels, prevailing wind patterns, and seasonal variations should also be noted.

How is the composition of a meteorite relevant to finding out the composition of the earths core?

Since the belief is that the Earth was formed by an enormous number of collisions of meteors, the iron would have collected at the core due to its mass. Many meteorites are about the same age as the solar system so they may resemble the material at the core.

Are planarians deuterostome?

They are neither a deuterostome or a protostome, since they only have one opening.

Mendel's law of independent Assortment states that alleles for different traits are passed on from one generation to the next independently of each other?

That's correct. Mendel's Law of Independent Assortment states that the inheritance of one trait is not dependent on the inheritance of another trait. This is due to the random alignment of homologous chromosomes during meiosis.

Is the force of the water on the piers the same at the water surface as it is 30m below the surface?

No, it would be less due to compression by weight of the surface area water. Every so many feet (meters) down, another "atmosphere" of pressure is exerted. Ergo, water at the seabed would exert more pressure on the pier than the water at the surface.

Is nickel found in the Caribbean?

Yes, nickel can be found in the Caribbean region. It is mined in countries such as Cuba, the Dominican Republic, and Venezuela. Nickel is often extracted from laterite deposits in these areas.

Why do different plants need different amounts of sunlight?

Different plants have evolved in different environments with various light conditions, leading to variations in their sunlight requirements. Plants have adapted to utilize sunlight for photosynthesis at different rates depending on their species, which determines how much sunlight they need to thrive. Factors such as leaf structure, pigment content, and physiological adaptations also influence a plant's sunlight requirements.

Granite is an example It forms deep underground It needs heat to form What is it?

Granite is an igneous rock that forms deep underground from the cooling of molten magma. It requires heat and pressure to form, typically found in the Earth's crust.
