Where the land is flat, ________ exerts a minimal influence on topographic development. where the land is flat, ________ exerts a minimal influence on topographic development. gravity water mechanical weathering chemical weathering biological weathering?

Answers

The correct answer is - gravity.
The gravity with it's pulling force puts pressure on the objects by pulling them downwards, which with the help of few other factors makes the objects break and fall, and thus change the relief forms. But this is only when there's something in a position that means that it can fall downwards, but this is lacking on a flat land because there's nowhere where the object can be pulled and fall down.

Earth can be called a "spaceship" because it takes up volume in space.
a. True

What danger is there when hail diminishes or stops entirely?

Answers

Hail often diminishes or ceases right before the arrival of a tornado.

Answer:

The danger of the possibility of a tornado arises when hail diminishes or stops entirely.

Explanation:

When there an updrafting of supercells of thunderstorms, hail is most likely to take place. It is observed many times that a tornado follows a hail. Especially when the hail diminishes or stops entirely all of a sudden after hailing for a short period of time. This happens because a tornado and a hail are both generated through a similar process called the updraft.

On a geologic map, strike represents the directional orientation of a fault.

Answers

This is TRUE

Strike is a way of representing the 3D orientation of a planar surface on a 2D map. Fault can be characterized by brittle deformation in rocks. These faults can be oriented at any direction (Strike). Shear stresses can produce faults where movement can occur in strike direction.



Answer:

The statement that says 'on a geologic map, strike represents the directional orientation of a fault' is false.

Explanation:

If it is considered that the given geologic map is of a horizontal plane, then the 'direction of the rock' present on this horizontal plane would be represented by a strike on the given geologic map. To represent a fault on the 'geologic map', the symbol of a thick line inclined towards the right is used.

What is the Northern European Plain's excellent soil is called?

Answers

One of the greatest uninterrupted expanses of plain on earth's surface
Answer:

Northern European Plain's excellent soil is called loess.

Explanation:

The European continent has varying deposits of loess soil from few decimeters to thick tens of meters. The Northern European countries whose soil predominantly loess are France, Poland, Germany, and northern Ukraine.  

The soil in this area is due to periglacial conditions. Loess results from built-up of wind-blown dust/silt that forms sedimentation. The silt particle is normally 20-50 micrometer in size that consists of less clay and a balanced quantity of sand and silt. It is homogenous soil which is also porous.

Part B in the previous question, how does the weight of the larger prism compare to the weight of the smaller prism

The weight of the larger prism is twice the weight of the smaller
The weight is 4 times the weight of the smaller one
The weight is 16 times the weight of the smaller
The weight is 64 times the weight of the smaller

Answers

A regular pentagonal prism has 9 centimetre base edge. A larger, similar prism of the same material has 36 cm base edge. After comparing, The weight of the larger prism is 64 times the weight of the smaller prism.

Answer: Option B

Explanation:

The relationship between weight and volume is indirect yet relative in nature. The volume of an object is the space that is occupied by the respective object, whereas, the weight of the object is its mass. The smaller and the larger prism are made of the same uniform material.

Given values in ratios as 9:36, it can be written as 1:4. So, then the volume is the cubic value,

                 [tex]1^{3}: 4^{3}[/tex] = 1:64

It is found after comparing the weight of the larger prism to the weight of the smaller prism that the weight of the larger prism is 64 times the weight of the smaller prism.

Answer:

Explanation:

Answer: Option D.

Explanation:

Weight is referred to as the mass of an object. It measures the quantity of matter in an object. Volume is the amount of space being occupied by an object. The smaller and the larger prism have the same uniform material.

The ratios of the smaller to the larger prism is  9:36.  

9/36 = 1/4.

So, then the volume is three times the value of 1/4 which is the cubic value.

1/4 × 1/4 × 1/4 = 1/64.

                 = 1:64

From the calculation, it can be deduced that the weight of the larger prism  is 64 times the weight of the smaller prism.

What happens to the surfaces of bodies without an atmosphere and no erosion?

Answers

If there's no atmosphere and no erosion than the surface of the bodies remains the same, unchanged. The atmosphere causes the erosion, be it mechanical, chemical or organic (indirectly), and all of the erosion types cause the surfaces of the bodies to change their forms over time because they break them apart, either in small or big pieces. So once the atmosphere is non existent, the erosion is automatically non existent as well, thus the surface of the bodies remains as it is.

what kind of fossil aging is used when scientists use the law of superposition?

Answers

When scientists use the law of superposition to determine the age of a fossil, they go by the principle of 'every undisturbed layer of rock is older than the layer above it. This is not the most precise way of determining age, and in fact this method can only reveal the approximate age, but not the exact one.

Answer:

When scientists use the law of superposition, the type of fossil aging they use is known as relative aging.

Explanation:

Scientists use different methods of aging to determine the 'age of rock fossils'. One of these techniques is that of relative aging. In this technique, the scientists 'determine the age of the bottom-most rock fossil' first and go by the principle that every new layer of rock superpositioned above the lower rock is comparatively younger than the lower rock.

The answer is - a scarcity of natural resources.

This is not a reason at all for poverty in Brazil. Brazil is a country that has abundance of natural resources, oil, gas, timber, water, minerals, you name it. The problem is the way in which this resources are used, not the lack of them. The way of usage of them is suitable for the rich who take the biggest piece of the 'pie', while the poor population barely sees any benefit from them.

Secondary seismic waves (s waves) ______. are the slowest seismic waves travel through solids, liquids, and gases

Answers

the answer to this question for this question is what we call a sS wave

Secondary seismic waves or s waves are the slowest seismic waves that travel through solids, liquids and gasses.

What are seismic waves?

A seismic wave is a wave of acoustic energy that travels through the Earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy.

Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones or accelerometers. Seismic waves are distinguished from seismic noise which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources.

The propagation velocity of a seismic wave depends on the density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle but drops sharply going from the mantle to Earth's outer core.

Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocenter. In geophysics, the refraction or reflection of seismic waves is used for research into Earth's internal structure.

Scientists sometimes generate and measure vibrations to investigate shallow, subsurface structures.

Tidal ranges will be greatest when the earth and the moon are at

Answers

Tidal ranges will be greatest when the Earth and the Moon are at their closest distance. 
The Moon with it's gravitational field, pulling force, causes the water on Earth to rise, on the part faced towards the Moon, and to retreat, on the part of the Earth that is not faced towards the Moon. The closer the Earth and the Moon are, the bigger the influence from the Moon and the Earth's surface waters, thus the bigger the tidal range.
