Answer:
Convection currents
Explanation:
Convection currents are defined as the vertical movement of heat or moisture(energy) from one location to another primarily due to the temperature changes within the substance. Some of the examples of convection current may include boiling water, convection currents in the atmosphere and in the ocean, weather changes, campfires, etc. Thus, the air that moves in huge circular patterns as a result of temperature differences is known as convection currents.
Does density-dependent usually wipe out entire
populations?
Answer : What are density dependent limits on population?
Density Dependent Limiting Factors
The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.

What do geographers not use to determine absolute location
Answer:
Geographers can describe the location of a place in one of two ways: absolute and relative. Both are descriptives of where a geographic location is.
Absolute location describes the location of a place based on a fixed point on earth. The most common way is to identify the location using coordinates such as latitude and longitude. Lines of longitude and latitude crisscross the earth. Latitude is used to mark the north-south position of a location on the Earth’s surface and ranges from 0 degrees at the equator to 90 degrees at the North and South Poles. There are 180 degrees of latitude and the distance between each degree of latitude is roughly 69 miles (111 km).

B. Magma is less dense than lava
C .Magma is formed deep in earth in lava forms near the surface of earth
D.Magma makes Igneous rocks and lava forms volcanoes
Answer: C
Explanation:
Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
In 2000, a population
of a city is one million
people. If it has a
doubling time of 25
years, when will its
population reach two
million?
Answer:
The population of the city will reach 2 million people in 2025.
Explanation:
The city in question has one million people. The doubling time of the population is estimated at 25 years. Double of one million is two million, and with the population being one million in 2000, 2025 will be the year when the city will have a population of two million since the doubling time is 25 years.
s Doubling of the population in 25 years is not something that happens rarely, but it mostly happens in smaller cities or towns, as the population needed for doubling the preexisting one shouldn't be that large. A city of one million people to double its population in just 25 years is another story. Such a scenario will mean a highly centralized region, with most of the region getting depopulated, while the city in question gets a huge amount of new residents, causing a lot of urbanistic challenges.
