Fluid basalt flows can extend tens of kilometers from an erupting vent. The leading edges of basalt flows can travel as fast as 10 km/h (6 mph) on steep slopes but they typically advance less than 1 km/h (0.27 m/s or about 1 ft/s) on gentle slopes.
Help plz, answer all
1. What impact did Portugal have on Latin America? Is it still evident today?

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
Answer:C
Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.
B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere
C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.
D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

Evaluate (Two-fifths) cubed. Check all that apply.
The exponent is Two-fifths.
The expanded form is (Two-fifths) (two-fifths) (two-fifths).
The expanded form is StartFraction 2 times 2 times 2 Over 5 EndFraction.
(Two-fifths) cubed = StartFraction 6 Over 15 EndFraction
(Two-fifths) cubed = StartFraction 8 Over 125 EndFraction

Which of the following is an example of balanced forces?
A.
A light bulb filament glows when a current moves through a wire.
B.
A person in a hot air balloon ignites the burner, which makes the balloon rise.
C.
A seesaw remains stationary when two students of equal weight sit on the ends.
D.
A driver slams on the car brake, and the car comes to a stop.
A seesaw remains stationary when two students of equal weight sit on the ends
c
Answer:
the answer is c.
Explanation:
a balanced force is a constant motion, or when the object does not move. because the children have the same weight, they can manage the seesaw to stay still.
