The cross symbol on a contour map typically indicates the location of a benchmark, which is a point of known elevation used as a reference for determining the elevation of other points on the map. It serves as a fixed point for surveyors and map users to use as a reference for measuring heights and depths.

Lions are consumers because they obtain their energy by consuming other organisms, typically herbivores like zebra or antelope. They do not produce their own food through photosynthesis, making them a part of the food chain as a secondary or tertiary consumer.

The rock is most likely slate, which is a fine-grained metamorphic rock composed of clay minerals such as muscovite, chlorite, and quartz. Slate's ability to split into thin sheets makes it suitable for shingles, blackboards, and other applications where a flat surface is desired.

Farmers commonly use alfalfa, clover, and ryegrass as fodder for cattle. These plants are rich in nutrients and provide essential proteins and fibers needed for the cattle's diet. Rotation and diversity in fodder help maintain a balanced and healthy diet for the cattle.

An ice block mixed with rocks is commonly referred to as a glacier. Glaciers form when compacted snow turns into ice over time, and they can incorporate rocks and debris as they move and erode the landscape.

A hen sits on the eggs to keep them warm and safe from predators. She turns the eggs regularly to ensure they develop properly. The hen also provides moisture by gently dampening the eggs with her beak.

There are several possible answers: * Natural gas is a mixture of hydrocarbons, mostly methane. * Propane is used instead of natural gas in areas where it does not make economic sense to install natural gas pipelines. * Butane is commonly used in camping stoves.

Yes, a fish fin and a whale flipper are considered analogous structures because they have similar functions (swimming) but are derived from different evolutionary origins. Fish fins are adaptations for movement in water, while whale flippers are modified limbs evolving from a common ancestor with land-dwelling mammals.

Earth takes 1 year for 1 orbit around the sun. So, in 100 years, Earth can orbit the sun 100 times.

No, planets do not share the same orbit. Each planet in our solar system travels along its own distinct path around the Sun. The varying distances and speeds of planets in their orbits prevent them from sharing the same orbit.

yes it , because it emitted its solar radiation upon all humankind and we laa felt it and served with it

The sun's radiant energy is a major factor in processes like photosynthesis, weather patterns, and climate regulation on Earth. It drives the growth of plants, heats the atmosphere leading to air circulation, and influences global temperature patterns.

We retired military, went through (survival training), learned whats called

Kentucky windage. You dont need a weather vein, BUT your finger. Yes your

pointer finger(clean) stick in a salivated mouth/water and the coolness of

which side of finger tells you from direction of wind.

Humans go through incomplete metamorphosis. This means that there is no distinct larval stage in human development, unlike in insects that go through complete metamorphosis with distinct stages like egg, larva, pupa, and adult.

Volcanic activity in the Pacific Northwest has led to the formation of the Cascade Range, including iconic peaks such as Mount St. Helens and Mount Rainier. Volcanic eruptions have played a significant role in shaping the landscape through the deposition of ash and lava flows, as well as creating fertile soils that support diverse ecosystems in the region. Additionally, volcanic activity has influenced the local climate and hydrology of the Pacific Northwest.

It depends on the current phase of the moon. If the moon is progressing from a new moon toward a full moon, it is waxing. If the moon is decreasing from a full moon toward a new moon, it is waning. You can check a lunar calendar or use a moon phase app to determine whether tomorrow's moon is waxing or waning.

In waterlily cells, the function of the vacuole is to store nutrients, water, and waste products. In fish cells, the function of the mitochondria is to produce energy in the form of ATP through cellular respiration. In paramecium cells, the function of the contractile vacuole is to regulate water content by pumping out excess water to maintain internal osmotic balance.

The North and South Poles are magnetically atrractive (allowing one to find North on a compass), and also they are used as "cooling units" for earth, maintaining its temperature. Global Warming may be causing the melting of the Polar Ice Caps due to the pollution of industrial factories, smoke stacks, and power plants, but it also may be a Solar Cycle (ending in 2012 and restarting, according to the Mayans), which would lead to the fact why an Ice Age happens once every 17,000 years.

A star is the object that forms from the contraction of a large sphere of gases, leading to nuclear fusion of lighter elements into heavier elements. This process releases energy in the form of light and heat.

Christian Doppler is best known for his discovery of the Doppler effect, which describes the change in frequency of a wave for an observer moving relative to its source. This effect is widely used in various fields, such as astronomy and medical imaging, to understand motion and velocity. Doppler's work laid the foundation for understanding how sound and light waves can be affected by relative motion.

Sediments form during the erosion and weathering processes that break down rocks into smaller particles. These sediments may then undergo deposition and compaction to form sedimentary rocks in the rock cycle.

The Mojave Desert centipede, also known as Scolopendra heros, is a venomous arthropod found in the deserts of the southwestern United States and Mexico. It can grow up to 6-8 inches long and has a striking coloration of red or orange with black bands. Its venom is used to immobilize prey such as insects, making it a beneficial predator in the ecosystem.

The asthenosphere is estimated to be approximately 100-200 kilometers thick. It is a semi-fluid layer in the upper mantle of the Earth that lies below the lithosphere and plays a crucial role in the movement of tectonic plates.

The inner core of the Earth is primarily composed of iron and nickel. These elements are believed to make up about 85% of the inner core, with the remaining portion likely consisting of lighter elements such as oxygen, sulfur, and silicon.

The treaty ushered in an epoch of peace and goodwill.
