If previous eruptions had left Mount St. Helens with a different shape, what differences might have influenced the timing of the eruption? CHOOSE ALL THAT APPLY. If the northern slopes had been less steep initially (same height), the eruption would likely have happened later. If the northern slopes had been steeper initially (same height), the eruption would likely have happened later. If the volcano had been significantly taller initially (same steepness), the eruption would likely have happened sooner. If the volcano had been significantly shorter initially (same steepness), the eruption would likely have happened sooner.

"Earth is both the planet we live on and the material we live from" (Suzuki, Chapter 4). From the following multiple choice selections below, which is not a specific statement covered in Chapter 4, Suzuki, Made from Soil. Soil offers far less to attract our attention than a marsh or tidal pool. Soil is a complex mixture of mineral particles, organic material, gases and nutrients. Mechanical and chemical weathering and how it impacts soil destroys all and is a means which ultimately does not produce life. Gaia or Gaea, is the mother goddess from whom everything else came forth. All growth, every harvest, comes from the dark, rich realm of the soil. The profile of fertile soil includes organic matter, air, water, and mineral matter.

What intertidal zone do sea anemones typically inhabit? spray zone upper intertidal middle intertidal lower intertidal

In general, how often do most cinder cones erupt? Most cinder cones erupt seasonally. Most cinder cones erupt several times each decade. Most cinder cones do not erupt. Most cinder cones erupt once. Most cinder cones erupt annually.
Most cinder cones erupt once
There had been many earthquakes in the area prior to this eruption. Why did this last earthquake trigger a massive landslide? Clearing of trees allowed erosion on the mountain slopes. Extensive rain had weakened the mountain slopes. Moving magma had over-steepened the mountain slopes.
Moving magma had over-steepened the mountain slopes
How can increased carbon dioxide uptake, or sequestration, by global forests change climate? Net global forest growth removes carbon dioxide from the atmosphere, thus cooling the earth's climate. As forests expand, carbon dioxide is lost to the atmosphere. Increased carbon sequestration leads to increased tsunami frequency. Carbon dioxide uptake by forests led to the end of the Pleistocene epoch. Increases in forest cover lead to increased flooding.

Why do farmers apply nitrogen to their fields in the spring and fall? Nitrogen prices are cheapest in spring and fall. Nitrogen is depleted through the use of pesticides on fields. Nitrogen is used to eradicate insects that will consume crop seedlings. Nitrogen provides nutrients to the plants for the coming growing season. Nitrogen is used to eradicate weeds and other plants that will compete with crops for soil nutrients.

The practice of leaving crop residue on the field between plantings to help prevent soil erosion is known as no-till agriculture. swidden. slash and burn agriculture. shifting cultivation.
No-till agriculture
Imagine that a fold has been eroded to a flat surface. In general, how would you know if this fold is plunging? Nonplunging folds look like straight lines at the surface, and plunging folds look like wavy lines. Nonplunging folds look like wavy lines at the surface, and plunging folds look like straight lines. Nonplunging folds look like valleys at the surface, and plunging folds look like hills. Nonplunging folds look like hills at the surface, and plunging folds look like valleys.

In which of the following regions would one likely find Spodosols? Tropical rainforests Savannas and grasslands Northern coniferous forests Deserts and semiarid areas
Northern coniferous forests
Why is the northern Gulf of Mexico described as a "dead zone"? Overfishing has disrupted the food chain in the Gulf, resulting in a cascade of localized extinctions Nutrient enrichment starts a chain of events that depletes the water of oxygen, making it difficult for aquatic life to survive. Nutrient enrichment makes ocean water less acidic and more difficult for aquatic life to survive in. The dead zone in the northern Gulf is nothing more than the expansion of an existing dead zone in the southern Gulf. Increased levels of nutrients are poisonous to fish and have resulted in Gulf-wide fish kills.

Which soil type is the most commonly found in the tropical rainy climates of South America? gelisols aridisols ultisols oxisols inceptisols

How will foliation in continental metamorphic rocks formed during subduction be oriented? perpendicular to the direction of plate movement oblique to the direction of plate movement parallel to the direction of plate movement

Based on the video, what can you infer about speciation--the process by which one species splits into two or more species? It is rare for new species to form on islands. Different species are typically very different in appearance, even if they are closely related. Physical separation of populations is often part of the speciation process. New species typically form as a consequence of new parasites or predators in the environment.

What is causing a decline in Antarctica's Chinstrap penguins? An increase in the leopard seal population, who feed on the penguins, Has impacted the penguin population. Warmer temperatures have allowed diseases to spread through the Chinstrap population. Unregulated hunting in the waters off Antarctica has decimated the population of these penguins. Populations of the penguin's major food source are declining because of melting sea ice. The Chinstrap penguins are not able to migrate back to breeding grounds in Antarctica by way of sea ice because the ice is disappearing.

How destructive was the tsunami generated by the earthquake? There was widespread damage along the South American coast and throughout the Pacific Ocean. The tsunami was approximately two meters high and destroyed some fishing boats. There was no damage, as the tsunami was less than one meter high. There was widespread damage along the South American coast. There was limited damage along the South American coast but widespread damage as the tsunami crossed the Pacific Ocean.

Remarkably, there were no deaths and only a few people were injured by falling debris. Approximately 100,000 deaths occurred and up to 3 million people were left homeless.

How do gray whales collect and eat such small organisms? They use their countershading to sneak up on their prey items. They emit high-pitched sounds that drive their prey items into tight masses. They use cooperative behavior to corral them into a group and then swallow their prey items whole. They use a technique called bubble-net feeding. They use their baleen to filter prey items from their environment.
